If we set the value as 10, the SNMP manager would receive a number of alarms which is proportional to number of routers.

Authors, Based on the poll-related discussion, it seems that we have consensus (albeit a bit reluctant) on RSVP-TE communicating the Z9 Tunnel_Num to the ingress of a corouted bidirectional LSP to meet the requirements of RFCs 6370 and 6428. Based on the discussion and confusion related to the draft, we ask that you revise your draft to limit its scope (discussion & solution) to just this requirement. Once this revision is made, the WG can then decide how move this work forward.

[SUN] Okay. I would say "connectivity" captures our intention more accurately.

Be noted that the serialization/de-serialization process on the control path are also relevant. In our current definition, the serialization/de-serialization delay of control packets are counted in the overall delay and this seems reasonable to me. On the data path part, the current definition requires a test signal being sent before control messages are sent. So the serialization of data path signals on the sending side will not influence delay measurement. However, we do have a de-serialization delay on the receiver side. In the current definition, we say: "...an error free signal is received..." By this, we intend to define the reception of test signals in a very general way since specific data path technologies are out of scope. However, by this definition, we have included the de-serialization delay into the overall delay in packet interface cases. When very long test frames are sent, the obtained delay will be notably longer than the actual value. To address this concern, I suggest the following text being added in the Discussion section of each metric: The accuracy of this metric is also dependent on the physical layer serialization/de-serialization of the test signal for certain data path technologies. For instance, for an LSP between a pair of low speed Ethernet interfaces, the time needed to serialize/deserialize a large frame may not be negligible. In this case, it is RECOMMENDED that the ingress (or egress) node uses small frames. The average length of the frame MAY be reported. Hope this will address Al's concern.

Isn't this already covered in draft-ietf-ccamp-assoc-ext? I thought both your document and ietf-ccamp-mpls-tp-rsvpte-ext-associated-lsp could use any association object. If you want to ensure this is understood, you can always add something in this document and in draft-ietf-ccamp-mpls-tp-rsvpte-ext-associated-lsp along the lines of: "The Association Types defined in this document MAY be used with any ASSOCIATION object type. For example, the Extended ASSOCIATION object defined in [assoc-ext] can be used when Global ID based identification is desired." or is there something more to it?

Title : Label Switched Path (LSP) Data Path Delay Metrics in Gen= eralized MPLS/ MPLS-TE Networks Author(s) : Weiqiang Sun Guoying Zhang Filename : draft-ietf-ccamp-dpm-06.txt Pages : 33 Date : 2012-06-08 When setting up a label switched path (LSP) in Generalized MPLS and MPLS/TE networks, the completion of the signaling process does not necessarily mean that the cross connection along the LSP have been programmed accordingly and in a timely manner. Meanwhile, the completion of signaling process may be used by applications as indication that data path has become usable. The existence of this delay and the possible failure of cross connection programming, if not properly treated, will result in data loss or even application failure. Characterization of this performance can thus help designers to improve the application model and to build more robust applications. This document defines a series of performance metrics to evaluate the connectivity of data path in the signaling process.

As to some Operation, Administration and Maintenance (OAM) functions, such as Connectivity Verification (CV) [RFC6428], source MEP_ID must be inserted in the OAM packets, so that the peer endpoint can compare the received and expected MEP_IDs to judge whether there is a mis-connnectivity defect [RFC6371], which means that the two MEP nodes need to pre-store each other's MEP_IDs. This document defines the signaling extensions to communicate the local assigned Z9-Tunnel_Num to the ingress LSR (Label Switching Router) of a co-routed bidirectional LSP.

The following are *my notes* from the call as well as one correction based on e-mail from Sergio. This mail is to let others know what was discussed, and to move any subsequent/resulting discussion to this list. Lou Attendees: Sergio Belotti Lou Berger Daniele Ceccarelli Cyril Margaria Khuzema Pithewan Zhangxian (Xian) Topic 1: How to represent TSG? - Authors stated TSG is needed for penultimate hop outgoing interface selection by path computation / loose ERO expansion - This means G-PID is not the right choice - Simply using PT values doesn't work as of the ODU0/OPU1 case (see G.709 Table 7-10) - Agreed upon approach: Have Encoding Type represent AMP & GMP. o Per G.709 Table 7-10, when combined with signal type, can understand TSG. o Existing type 12 (from rfc4328) will represents AMP o A new type will be assigned from IANA (15?) to represent GMP [After the call Sergio pointed out that there is one case where AMP is ambiguous -- ODU2/OPU3 so now considering to per PT values] - Sergio had an open question: Is a type needed to represent both 1.25 & 2.5 TSG, i.e., is there a case where AMP/GMP is changed after LSP establishment? Action: Authors/all to consider question. (presumed answer is no.) Topic 2: How to represent G.709 Payload Types (See Table 15-8)? - Agreed that PT should be represented in G-PID. This follows the approach taken by RFC4328 section 3.1.3. - Lou had an open question: Are there any missing G-PID values based on G.709 (see Table 15-18)? Action: Authors/all to consider question. (Authors must confirm.) Topic 3: ADAPTATION Object - Agreed Type=1 is no longer needed - Agreed Type 2 applies to H-LSPs when H-LSPs/LSPs terminate on same egress. - Authors will add an example in the routing draft for such a case, and will be referenced by signaling draft - Agreed that the draft scope is intra-layer hierarchy, inter-layer is MLN. (Based on discussion on interface selection based on client adaptation.) - Agreed that Mapping field will be replaced by a reserved field - Lou had an open question: Can the Hierarchy TLV be carried in an existing object, e.g., LSP_REQUIRED_ATTRIBUTES Object?

When we agreed on using Exising type 12 for AMP and a new code for= GMP we didn't take into account this MUST from RFC4328. A transit or an egress node (receiving a Path message containing a GENERALIZED_LABEL_REQUEST object) MUST generate a PathErr message, with a "Routing problem/Unsupported Encoding" indication, if the requested LSP Encoding Type cannot be supported on the corresponding incoming interface. I'm not sure we can still use the Encoding type.

Sure, a transit node may not support 1.25 TSG (or GMP) *termination*, but it does support it for transit signals/LSPs. So, I don't see any issue with meeting the encoding requirement on a transit node. BTW transit nodes not supporting termination of an LSP's encoding type is certainly not a new issue/fature for GMPLS...

As I said in my previous mail. Support for transit is not the same as support for termination. Consider the case of an STM-64 carried over a lambda over a WDM network. Nothing precludes the ingress signaling the LSP as SDH encoded, and the WDM network transparently (from the SDH perspective) carrying the signal across the WDM links. As RFC 3471 says: The Generalized Label Request carries an LSP encoding parameter, called LSP Encoding Type. This parameter indicates the encoding type, e.g., SONET/SDH/GigE etc., that will be used with the data associated with the LSP. The LSP Encoding Type represents the nature of the LSP, and not the nature of the links that the LSP traverses. Keep in mind that the control plane just automates setup of the data plane. If the data plane can 'support' something the control plane should also 'support' it. Rather than talking theory, let's try to be specific: What data plane case(s) are you concerned about? What information is missing from the control messages to setup/modify/etc, i.e., 'support', the data plane?

Sure. As I said in my previo= us mail.  Support for transit is not the same as support for terminati= on.  Consider the case of an STM-64 carried over a lambda over a WDM n= etwork.  Nothing precludes the ingress signaling the LSP as SDH encoded, and the WDM network transparently (from the SDH pe= rspective) carrying the signal across the WDM links.

 

[Fatai] I assume that= you are talking about multi-layer scenario. When an SDH LSP is being creat= ed, every node should support SDH encoding type (encoding type =3D5 SDH ITU-T G.707) fro= m SDH layer perspective no matter what server layer will be transmitted ove= r. Regarding SDH over lambda case, if an SDH LSP needs to be carried over a lambda, a lambda LSP(FA-LSP) should be crea= ted with the requested encoding type =3D 8 Lambda (every node along this la= mbda LSP should support lambda encoding) before this SDH LSP (with encoding= type =3D SDH) establishment is completed.

 

As RFC 3471 says:=

 

The Generalized Label Reques= t carries an LSP encoding parameter, called LSP Encoding Type. This paramet= er indicates the encoding type, e.g., SONET/SDH/GigE etc., that will be use= d with the data associated with the LSP.  The LSP Encoding Type represents the nature of the LSP, and not= the nature of the links that the LSP traverses.

 

[Fat= ai] Understood.

&= nbsp;

Keep in mind that the contro= l plane just automates setup of the data plane.  If the data plane can= 'support' something the control plane should also 'support' it.=

 

Rather than talking theory, = let's try to be specific:

 

What data plane case(s) are = you concerned about?

 

What information is missing = from the control messages to setup/modify/etc, i.e., 'support', the data pl= ane?

&= nbsp;

[Fat= ai] Nothing is missed. I think the discussion is about where to carry the o= riginal TSG/PT information. As I said in another email, the TSG/PT informat= ion is the capability of the server layer (FA-LSP that is being created) that exports to its client layer (e.g, an O= DU2 FA-LSP is being created to support subsequent ODU1s with TSG=3D1.25Gbps= ) and it only makes sense to the end points and penultimate hop of the FA-L= SP (ie., TSG/PT should be transparent to the other transit nodes of the FA-LSP). Based on the role of the TSG/PT= information, I suspect the Encoding Type is not the right place to carry t= he equivalent TSG/PT information, because I think Encoding type is an end-t= o-end constraint (at FA-LSP specific layer) (ie., the Encoding type should be supported by all the nodes instea= d of some of the nodes (e.g, end points and of penultimate hop) of the FA-L= SP).

&= nbsp;

Hi all,

 

I think what Fatai = is going to stress is the basic assumption that bring us (as co-authors) to propose another way to carry TSG/PT info .

Also my understandi= ng of Encoding Type was that, how to carry a payload (the sense of Encoding ) has= to be checked along all the path and not only in penultimate/end points.<= /o:p>

As explained by Fat= ai (and described in the g709INFO draft) the TSG/PT  information has a do= uble face: one is the TSG used itself by the server at the creation , the other = is what =A1=B0provided=A1=B1 towards clients.

This information is needed to permit the right correspondence at the end points of the specific adaptation for the client LSP.

So , when the serve= r exports this information ,this information does not need to be checked alon= g the entire path. In the Encoding Field there will be information regarding = =A1=B0his nature=A1=B1 , that is not the type of information as TSG/PT.

 

So, it seems as tho= ugh another type of construct should be more conceivable and correct to carry t= his info.

 

Thanks

 

Sergio

Sure. As I said in my previous mail.  Suppo= rt for transit is not the same as support for termination.  Consider the case= of an STM-64 carried over a lambda over a WDM network.  Nothing precludes= the ingress signaling the LSP as SDH encoded, and the WDM network transparently (from the SDH perspective) carrying the signal across the WDM links.

 

[Fatai] I assume that you are talking about multi-layer scenario. When an SDH LSP is being created, every node should support SDH encoding type (encoding type =3D5 SDH ITU-T G.707) from SDH layer perspecti= ve no matter what server layer will be transmitted over. Regarding SDH over lambd= a case, if an SDH LSP needs to be carried over a lambda, a lambda LSP(FA-LSP) should be created with the requested encoding type =3D 8 Lambda (every node= along this lambda LSP should support lambda encoding) before this SDH LSP (with encoding type =3D SDH) establishment is completed.

 

As RFC 3471 says:

 

The Generalized Label Request carries an LSP enc= oding parameter, called LSP Encoding Type. This parameter indicates the encoding type, e.g., SONET/SDH/GigE etc., that will be used with the data associated with the LSP.  The LSP Encoding Type represents the nature of the LSP,= and not the nature of the links that the LSP traverses.

 

[Fatai] Understood. <= /span>

 

Keep in mind that the control plane just automat= es setup of the data plane.  If the data plane can 'support' something th= e control plane should also 'support' it.

 

Rather than talking theory, let's try to be spec= ific:

 

What data plane case(s) are you concerned about?=

 

What information is missing from the control mes= sages to setup/modify/etc, i.e., 'support', the data plane?

 

[Fatai] Nothing is mi= ssed. I think the discussion is about where to carry the original TSG/PT informatio= n. As I said in another email, the TSG/PT information is the capability of the server layer (FA-LSP that is being created) that exports to its client laye= r (e.g, an ODU2 FA-LSP is being created to support subsequent ODU1s with TSG=3D1.25Gbps) and it only makes sense to the end points and penultimate h= op of the FA-LSP (ie., TSG/PT should be transparent to the other transit nodes of= the FA-LSP). Based on the role of the TSG/PT information, I suspect the Encodin= g Type is not the right place to carry the equivalent TSG/PT information, bec= ause I think Encoding type is an end-to-end constraint (at FA-LSP specific layer= ) (ie., the Encoding type should be supported by all the nodes instead of som= e of the nodes (e.g, end points and of penultimate hop) of the FA-LSP).

This really shouldn't be that hard. As I mentioned in my previous message (and on the call) our control plane representation/modeling should follow the data plane. If TSG is an attribute of signal encoding on *any* link, encoding type is perfectly reasonable place to carry the information. If TSG is purely an issue of adaptation, than I suspect it really is an MLN issue. you said: > [Fatai] Nothing is missed. I think the discussion is about where to > carry the original TSG/PT information. As I said in another email, the > TSG/PT information is the capability of the server layer (FA-LSP that is > being created) that exports to its client layer (e.g, an ODU2 FA-LSP is > being created to support subsequent ODU1s with TSG=1.25Gbps) and it only > makes sense to the end points and penultimate hop of the FA-LSP (ie., > TSG/PT should be transparent to the other transit nodes of the FA-LSP). So, let's try to understand this a bit deeper. What is happening *in the data plane* on the penultimate link that it needs to understand TSG?

So "support" requirements can be completely different for transit nodes than for edge/2nd/penultimate nodes.

Sure. As I said in my previous mail. = Support for transit is not the same as support for termination.  Cons= ider the case of an STM-64 carried over a lambda over a WDM network.  = Nothing precludes the ingress signaling the LSP as SDH encoded, and the WDM= network transparently (from the SDH perspective) carrying the signal acros= s the WDM links.

 

[Fatai] I assume that you are talking a= bout multi-layer scenario. When an SDH LSP is being created, every node sho= uld support SDH encoding type (encoding type =3D5 SDH ITU-T G.707) from SDH= layer perspective no matter what server layer will be transmitted over. Re= garding SDH over lambda case, if an SDH LSP needs to be carried over a lamb= da, a lambda LSP(FA-LSP) should be created with the requested encoding type= =3D 8 Lambda (every node along this lambda LSP should support lambda encod= ing) before this SDH LSP (with encoding type =3D SDH) establishment is comp= leted.

 

JD:  The Encoding Type of =A1=AEP= hotonic=A1=AF is meant to have a special meaning which is that because it i= s transparent, it supports a multiplicity of digital encoding schemes. = ; (One of the early GMPLS RFCs mentions this, but I can=A1=AFt remember whi= ch.)

 

<= span style=3D'font-size:11.0pt;color:#1F497D'>So, if you are dedicating an = entire lambda  to an SDH LSP, there is no need to bring up a hierarchi= cal lambda LSP whose endpoints support SDH switching.  Rather, the SDH= LSP can be directly routed over links (more precisely interfaces) whose En= coding Type is =A1=AEPhotonic=A1=AF and whose =A1=AESwitching Capability=A1= =AF is =A1=AELambda=A1=AF.  This was routinely done when I was at Cali= ent.

And we agreed that non-OTN MLN will be handled as MLN without OTN-specific additions. One of the other authors (Daniele) also mentioned that there is another draft forthcoming on the topic. To me, speaking as a WG contributor, there are really two possible directions to take from the technical perspective: 1) Treat the intra-OTN (hierarchy) case as MLN 2) Bundle some upper OTN hierarchy information as part of a lower H-LSPs I'm conflicted on this point. I/some of us went down the path of 2 in the early days of GMPLS as part of our implementation and, while expedient, it really had long term drawbacks as compared to a clean MLN/hierarchy solution. That said, there seems to be support in the WG for some form intra-OTN "optimization". Assuming we're going down the path of 2, I think the approach from the conference call is a reasonable middle ground, i.e., A) TSG represented in LSP encoding B) higher level OTN (only) information carried when signaling an H-LSP (preferably in an existing object). And this *is* a compromise position. From a GMPLS-purest standpoint, IMO this approach is co-mingling layers. With respect to the concern raised by Fatai on LSP Encoding Type. IMO a node's support for a specific encoding type value has always had to be determined in the context of the node's role (transit vs non-transit/PH) as well as the switching type. This is consistent with fielded GMPLS implementations, the RFC text I previously quoted, and John's mail. You can also make this point explicit in the g709v3 document. So, I do *not* agree that the proposed representation of TSG in LSP Encoding Type is incompatible with the definition of the field. There may be some other issue I missed, if so, please raise it! Otherwise I propose that the WG move forward with the "A+B" approach as the solution for an integrated-OTN "2" direction. Alternatively, and if the author's prefer, I suggest revisiting a more traditional MLN-based solution for intra-OTN hierarchy, i.e., a "1" type direction.

WSON RWA Information draft (http://datatracker.ietf.org/doc/draft-i= etf-ccamp-rwa-info/) and 2. WSON Generic Encoding draft (http://datatracker.ietf.org/doc/draft-= ietf-ccamp-general-constraint-encode/). The authors of the WSON RWA information drat believe that the draft is stab= le and can move forward to WG LC. Please bring up any issues you are aware = of this draft before we are ready to move on. Regarding the WSON Generic Encoding draft, we have a couple of issues we ne= ed to discuss. The first one is how the current generic encoding deals with= flex-grid issue. The second issue is where to put ISCD encoding. * Let's discuss the first issue. As part of the WSON generalization= effort the WSON Info draft and the General Constraints encoding draft repr= esents link resources (spectrum, time slots, etc...) in a general way in th= e. This should is applicable to Flex Grid and other technologies. In section 7.1 of the WSON Info Model we define two important types of link= information "available labels" and "shared backup labels". These fields ar= e used to indicate the availability of link "resources". This is similar to= the notion of the use of the Label Set of RFC3471 (GMPLS signaling). Note = that in MPLS RSVP signaling, RFC3209, there is also the notion of "label ra= nge" restriction (from the old ATM and Frame Relay days). In MPLS, labels = do not represent link bandwidth resources (spectrum, time slot, etc.) while= in most GMPLS technologies they do. From the WSON routing and general cons= traint routing perspective we are concerned with the link "resources" and t= he "available labels" serves this purpose. In section 2.2 of the General Constraint Encoding draft we define a Label S= et field that is then used to represent available resources on a link. Thes= e resources may be time slots within a SONET/SDH or G.709 hierarchy or chun= ks of frequency spectrum in a WDM system. In appendix A.2 of the General Co= nstraint Encoding draft we give examples for the WSON case based upon the l= abel format in RFC6205. However the mechanisms of the Label Set field could= be used with SONET/SDH label encoding of RFC4606. It should be noted that= many pre-standard GMPLS systems from different vendors all used bit maps t= o track SONET/SDH time slots. Flex-grid systems (G.694.1 2012) work with a= n ITU-T grid and center frequency hence one can still use the Label Set fie= ld to represent optical frequency spectrum resources. One could use a new l= abel type as a base or a RFC6205 label type with finer granularity. If one= wishes to restrict the choices used with a particular technology that coul= d be handled in a technology specific OSPF extension. This implies that whe= n flex grid work becomes a viable CCAMP work, the current generic encoding = works very well with the anticipated extension to flex-grid based WSON (SSO= N). Any encoding changes due to flex-grid can be added into technology spec= ific OSPF extension. The development of flex-grid would not and should not = interfere with the current generic encoding draft. * The second issue is where to put the "available labels" and "shar= ed backup labels" information. As we pointed out above these fields were designed to be applicable to mult= iple technologies (TDM, WSON, Flex grid). These are link specific and "dyn= amic" (can change with subsequent LSP addition or removal). It has been sug= gested that this information could be added to the ISCD of RFC4203. This is= somewhat problematic, though maybe not prohibitively so. First the availab= le place for this would be the "Switching Capability-specific information" = field. Currently this field is defined for TDM and for LSC "there is no Swi= tching Capability specific information field present." An alternative woul= d be to define new sub-TLVs of the TE-Link TLV. Are there strong opinions = out there? It seems that trying to use the ISCD has more impact on previous= RFCs.

Hi,

 

Just wanted to reca= p and start a discussion for

 

1.      WSON RWA In= formation draft (http://datatracker.ietf.org/doc/draft-ietf-ccamp-rwa-info/= ) and

2.      WSON Generi= c Encoding draft (http://datatracker.ietf.org/doc/draft-ietf-c= camp-general-constraint-encode/).

 

The authors of the = WSON RWA information drat believe that the draft is stable and can move for= ward to WG LC. Please bring up any issues you are aware of this draft befor= e we are ready to move on.

 

Regarding the WSON = Generic Encoding draft, we have a couple of issues we need to discuss. The = first one is how the current generic encoding deals with flex-grid issue. T= he second issue is where to put ISCD encoding.

 

·         Let’s= discuss the first issue. As part of the WSON generalization = effort the WSON Info draft and the General Constraints encoding draft repre= sents link resources (spectrum, time slots, etc...) in a general way in the= . This should is applicable to Flex Grid and other technologies.<= /o:p>

 

In section 7.1 of the WSON Info = Model we define two important types of link information "available lab= els" and "shared backup labels". These fields are used to in= dicate the availability of link "resources". This is similar to the not= ion of the use of the Label Set of RFC3471 (GMPLS signaling). Note that in = MPLS RSVP signaling, RFC3209, there is also the notion of "label range= " restriction (from the old ATM and Frame Relay days).  In MPLS, labels do not represent link bandwidth resources (sp= ectrum, time slot, etc.) while in most GMPLS technologies they do. From the= WSON routing and general constraint routing perspective we are concerned w= ith the link "resources" and the "available labels" serves this purpose.

 

In section 2.2 of the General Co= nstraint Encoding draft we define a Label Set field that is then used to re= present available resources on a link. These resources may be time slots within a SONET/SDH or G.709 hierarchy or chunks of frequency= spectrum in a WDM system. In appendix A.2 of the General Constraint Encodi= ng draft we give examples for the WSON case based upon the label format in = RFC6205. However the mechanisms of the Label Set field could be used with SONET/SDH label encoding of RFC4= 606.  It should be noted that many pre-standard GMPLS systems from dif= ferent vendors all used bit maps to track SONET/SDH time slots.  Flex-= grid systems (G.694.1 2012) work with an ITU-T grid and center frequency hence one can still use the Label Set field to r= epresent optical frequency spectrum resources. One could use a new label ty= pe as a base or a RFC6205 label type with finer granularity.  If one w= ishes to restrict the choices used with a particular technology that could be handled in a technology specific OSP= F extension. This implies that when flex grid work becomes a viable CCAMP w= ork, the current generic encoding works very well with the anticipated exte= nsion to flex-grid based WSON (SSON). Any encoding changes due to flex-grid can be added into technology specifi= c OSPF extension. The development of flex-grid would not and should not int= erfere with the current generic encoding draft.

 

·         The second issue is where to pu= t the "available labels" and "shared backup labels" inf= ormation.

 

As we pointed out above these fi= elds were designed to be applicable to multiple technologies (TDM, WSON, Fl= ex grid).  These are link specific and "dynamic" (can change with subsequent LSP addition or removal). It has been suggested that this = information could be added to the ISCD of RFC4203. This is somewhat problem= atic, though maybe not prohibitively so. First the available place for this= would be the "Switching Capability-specific information" field. Currently this field is defined for TDM and for L= SC "there is no Switching Capability specific information field presen= t."  An alternative would be to define new sub-TLVs of the TE-Lin= k TLV.  Are there strong opinions out there? It seems that trying to use the ISCD has more impact on previous RFCs.

Greg and Young=

This draft is a work item of the Common Control and Measurement Plane = Working Group of the IETF. Title : Routing and Wavelength Assignment Information Encoding f= or Wavelength Switched Optical Networks Author(s) : Greg M. Bernstein Young Lee Dan Li Wataru Imajuku Filename : draft-ietf-ccamp-rwa-wson-encode-14.txt Pages : 37 Date : 2012-04-24 A wavelength switched optical network (WSON) requires that certain key information elements are made available to facilitate path computation and the establishment of label switching paths (LSPs). The information model described in "Routing and Wavelength Assignment Information for Wavelength Switched Optical Networks" shows what information is required at specific points in the WSON. Part of the WSON information model contains aspects that may be of general applicability to other technologies, while other parts are fairly specific to WSONs. This document provides efficient, protocol-agnostic encodings for the WSON specific information elements. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses. Such encodings can be used to extend GMPLS signaling and routing protocols. In addition these encodings could be used by other mechanisms to convey this same information to a path computation element (PCE).

This draft is a work item of the Common Control and Measurement Plane Work= ing Group of the IETF. Title : ASON Routing for OSPFv2 Protocols Author(s) : Andrew G. Malis Acee Lindem Dimitri Papadimitriou Filename : draft-ietf-ccamp-rfc5787bis-04.txt Pages : 29 Date : 2012-06-19 Abstract: The ITU-T has defined an architecture and requirements for operating an Automatically Switched Optical Network (ASON). The Generalized Multiprotocol Label Switching (GMPLS) protocol suite is designed to provide a control plane for a range of network technologies including optical networks such as time division multiplexing (TDM) networks including SONET/SDH and Optical Transport Networks (OTNs), and lambda switching optical networks. The requirements for GMPLS routing to satisfy the requirements of ASON routing, and an evaluation of existing GMPLS routing protocols are provided in other documents. This document defines extensions to the OSPFv2 Link State Routing Protocol to meet the requirements for routing in an ASON. Note that this work is scoped to the requirements and evaluation expressed in RFC 4258 and RFC 4652 and the ITU-T Recommendations current when those documents were written. Future extensions of revisions of this work may be necessary if the ITU-T Recommendations are revised or if new requirements are introduced into a revision of RFC 4258. This document obsoletes RFC 5787 and updates RFC 5786.

Recent examples can be found in the "Action" announcements for approved documents. The approval announcement contains the following sections: Technical Summary The RSVP ASSOCIATION object was defined in the context of GMPLS (Generalized Multi-Protocol Label Switching) controlled label switched paths (LSPs). In this context, the object is used to associate recovery LSPs with the LSP they are protecting. This object also has broader applicability as a mechanism to associate RSVP state, and this document defines how the ASSOCIATION object can be more generally applied. This document also defines extended ASSOCIATION objects which, in particular, can be used in the context of Transport Profile of Multiprotocol Label Switching (MPLS-TP). This document updates RFC 2205, RFC 3209, and RFC 3473. It also modifies the definition of the Association ID field defined in RFC 4872. Working Group Summary Was there anything in WG process that is worth noting? For example, was there controversy about particular points or were there decisions where the consensus was particularly rough? No. Good support by the WG. Document Quality Are there existing implementations of the protocol? Have a significant number of vendors indicated their plan to implement the specification? Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? If there was a MIB Doctor, Media Type or other expert review, what was its course (briefly)? In the case of a Media Type review, on what date was the request posted? There have been no public statements related to implementations, though significant interest was expressed by the working group. Personnel Who is the Document Shepherd?

Title : OSPF-TE Extensions for General Network Element Constrain= ts Author(s) : Fatai Zhang Young Lee Jianrui Han Greg Bernstein Yunbin Xu Filename : draft-ietf-ccamp-gmpls-general-constraints-ospf-te-03.txt Pages : 14 Date : 2012-06-19 Abstract: Generalized Multiprotocol Label Switching can be used to control a wide variety of technologies including packet switching (e.g., MPLS), time-division (e.g., SONET/SDH, OTN), wavelength (lambdas), and spatial switching (e.g., incoming port or fiber to outgoing port or fiber). In some of these technologies network elements and links may impose additional routing constraints such as asymmetric switch connectivity, non-local label assignment, and label range limitations on links. This document describes OSPF routing protocol extensions to support these kinds of constraints under the control of Generalized MPLS (GMPLS).

As Greg's previous email indicated, the OIC is defined to represent ma= ny fields, some of which are not relevant to WSON signal compatibility (for= example, S field =3D spectral excursion, W =3D span distance, z =3D fiber = type) and FEC is not defined in OIC. Besides, the WSON signal compatibility= needs to include processing capability (e.g., REG capable, and others), wh= ich is not defined by the OIC. The co-authors of the WSON info and encoding do not feel that OIC proposal = has much relevance to the current WSON signal compatibility encoding. We'd = like to close this issue and move on. Regards, Young From: ccamp-bounces@ietf.org [mailto:ccamp-bounces@ietf.org] On Behalf Of G= reg Bernstein Sent: Wednesday, April 18, 2012 2:12 PM To: ccamp@ietf.org Subject: Re: [CCAMP] Optical int class, changes to draft-ietf-ccamp-rwa-inf= o-14 Hi Giovanni, I still don't understand what problem the "Optical Interface C= lass" is addressing. You seem to be replacing something that is well define= d "modulation type" with something less precise, and removing the important= detailed FEC type information. For the non-impairment case in ITU-T G.959.1 where they define various "opt= ical tributary signal classes". This is the basis for the "modulation type"= in the WSON info draft. In GMPLS WSON extensions we are not trying to tak= e on the entire management plane we take a minimal subset needed for connec= tion provisioning. Perhaps if we just rename our "modulation type" to "opti= cal tributary signal class" this will clear up any confusion. Otherwise we= need to know more specifically what you think you need added and why you w= ant to remove the FEC type. ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create "= application codes" which describe link and signal attributes. These applica= tion codes have the form: DScW-ytz(v) where D indicates DWDM applications --> Why do you need or want this? DW= DM and CWDM data planes can't talk, LMP will tell you this S indicates maximum spectral excursion --> Sounds impairment relate= d... c is the channel spacing in GHz --> Wouldn't LMP catch this incompa= tibility?

Hi

 <= /p>

We haven’t heard an= y clarification from those who proposed “optical interface classes (O= IC) ” to replace the current WSON signal compatibility definition. As Greg’s previous email indicated, the OIC is defined to represent man= y fields, some of which are not relevant to WSON signal compatibility (for = example, S field =3D spectral excursion, W =3D span distance, z =3D fiber t= ype) and FEC is not defined in OIC. Besides, the WSON signal compatibility needs to include processing capability (e.g.= , REG capable, and others), which is not defined by the OIC.

 <= /p>

The co-authors of the WSO= N info and encoding do not feel that OIC proposal has much relevance to the= current WSON signal compatibility encoding. We’d like to close this issue and move on.

 <= /p>

Regards,

Young

Hi Giovanni, I still don't understand what problem t= he "Optical Interface Class" is addressing. You seem to be replac= ing something that is well defined "modulation type" with somethi= ng less precise, and removing the important detailed FEC type information.

For the non-impairment case in ITU-T G.959.1 where they define various &quo= t;optical tributary signal classes". This is the basis for the "m= odulation type" in the WSON info draft.  In GMPLS WSON extensions= we are not trying to take on the entire management plane we take a minimal subset needed for connection provisioning. Perhaps if we= just rename our "modulation type" to "optical tributary sig= nal class" this will clear up any confusion.  Otherwise we need t= o know more specifically what you think you need added and why you want to remove the FEC type.

ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create &= quot;application codes" which describe link and signal attributes. The= se application codes have the form: DScW-ytz(v) where
    D     indicates DWDM applications  -= -> Why do you need or want this? DWDM and CWDM data planes can't talk, L= MP will tell you this
    S     indicates maximum spectral excursio= n --> Sounds impairment related...
    c     is the channel spacing in GHz -->= ; Wouldn't LMP catch this incompatibility?
    W    is a letter indicating the span dist= ance (S =3D short haul, L long haul) --> This seems like coarse impairme= nt information
    y     indicates the the highest class of = optical tributary signal supported  --> From ITU-T G.959.1, already= have in WG draft.
    t     is a placeholder letter
    z     indicates the fiber type = --> This seems like very coarse grained impairment information.
    v     indicates the operating wavelength = range in terms of spectral bands --> Already have in more detail

We already explicitly support "y" (our more detailed modulation t= ype list) and "v" (we support the more detailed port wavelength c= onstraint explicitly).

Lyndon and other "Optical Interface Class" co-authors in the bay = area, perhaps we can meet and discuss.

Dear WG,

according to input from Lou here the suggested changes on draft-ietf-ccamp-= rwa-info-14  if the Optical Interface Class is used:

#1  Section 5.2
OLD:
<InputConstraints> ::=3D <SharedInput> [<ModulationTypeList&= gt;]
   [<FECTypeList>] [<BitRateRange>] [<ClientSignal= List>]

NEW:
<InputConstraints> ::=3D <SharedInput> [<OpticalInterfaceCla= ssList>] [<ClientSignalList>]


#2 Section 5.2
OLD:
<OutputConstraints> :=3D <SharedOutput> [<ModulationTypeList= >]
   [<FECTypeList>]

NEW:
<OutputConstraints> :=3D <SharedOutput> [<OpticalInterfaceCl= assList>]


#3 Section 5.3.1
OLD:
      5.3.2. Modulation Type List

      Modulation type, also known as optical tribu= tary signal class,
      comes in two distinct flavors: (i) ITU-T sta= ndardized types; (ii)
      vendor specific types. The permitted modulat= ion type list can
      include any mixture of standardized and vend= or specific types.

      <modulation-list>::=3D
      [<STANDARD_MODULATION>|<VENDOR_MODU= LATION>]...

      Where the STANDARD_MODULATION object just re= presents one of the
      ITU-T standardized optical tributary signal = class and the
      VENDOR_MODULATION object identifies one vend= or specific
      modulation type.

      5.3.3. FEC Type List

      Some devices can handle more than one FEC ty= pe and hence a list
      is needed.

      <fec-list>::=3D [<FEC>]

      Where the FEC object represents one of the I= TU-T standardized
      FECs defined in [G.709], [G.707], [G.975.1] = or a vendor-specific
      FEC.

      5.3.4. Bit Rate Range List

      Some devices can handle more than one partic= ular bit rate range
      and hence a list is needed.

      <rate-range-list>::=3D [<rate-range= >]...

      <rate-range>::=3D<START_RATE><= ;END_RATE>

      Where the START_RATE object represents the l= ower end of the range
      and the END_RATE object represents the highe= r end of the range.



NEW:
    5.3.2 Optical Interface Class List

    <OpticalInterfaceClassList> ::=3D <OPTICAL_INT_= CLASS> ...

    Where the term <OPTICAL_INT_CLASS> is defined by [= xyz].



for the info model, That's all folks
Cheers
G

Hi

 

We haven’t heard any clarification from those who proposed “optical interface classes (OIC) ” to replace the current WSON signal compatibility definition. As Greg’s previous email indicated, the OIC is defined to represent many fields, some of which are not relevant to WSON signal compatibility (for example, S field = spectral excursion, W = span distance, z = fiber type) and FEC is not defined in OIC. Besides, the WSON signal compatibility needs to include processing capability (e.g., REG capable, and others), which is not defined by the OIC.

 

The co-authors of the WSON info and encoding do not feel that OIC proposal has much relevance to the current WSON signal compatibility encoding. We’d like to close this issue and move on.

 

Regards,

Young

Hi Giovanni, I still don't understand what problem the "Optical Interface Class" is addressing. You seem to be replacing something that is well defined "modulation type" with something less precise, and removing the important detailed FEC type information.

For the non-impairment case in ITU-T G.959.1 where they define various "optical tributary signal classes". This is the basis for the "modulation type" in the WSON info draft.  In GMPLS WSON extensions we are not trying to take on the entire management plane we take a minimal subset needed for connection provisioning. Perhaps if we just rename our "modulation type" to "optical tributary signal class" this will clear up any confusion.  Otherwise we need to know more specifically what you think you need added and why you want to remove the FEC type.

ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create "application codes" which describe link and signal attributes. These application codes have the form: DScW-ytz(v) where
    D     indicates DWDM applications  --> Why do you need or want this? DWDM and CWDM data planes can't talk, LMP will tell you this
    S     indicates maximum spectral excursion --> Sounds impairment related...
    c     is the channel spacing in GHz --> Wouldn't LMP catch this incompatibility?
    W    is a letter indicating the span distance (S = short haul, L long haul) --> This seems like coarse impairment information
    y     indicates the the highest class of optical tributary signal supported  --> From ITU-T G.959.1, already have in WG draft.
    t     is a placeholder letter
    z     indicates the fiber type  --> This seems like very coarse grained impairment information.
    v     indicates the operating wavelength range in terms of spectral bands --> Already have in more detail

We already explicitly support "y" (our more detailed modulation type list) and "v" (we support the more detailed port wavelength constraint explicitly).

Lyndon and other "Optical Interface Class" co-authors in the bay area, perhaps we can meet and discuss.

Best Regards
Greg B.

Dear WG,

according to input from Lou here the suggested changes on draft-ietf-ccamp-rwa-info-14  if the Optical Interface Class is used:

#1  Section 5.2
OLD:
<InputConstraints> ::= <SharedInput> [<ModulationTypeList>]
   [<FECTypeList>] [<BitRateRange>] [<ClientSignalList>]

NEW:
<InputConstraints> ::= <SharedInput> [<OpticalInterfaceClassList>] [<ClientSignalList>]


#2 Section 5.2
OLD:
<OutputConstraints> := <SharedOutput> [<ModulationTypeList>]
   [<FECTypeList>]

NEW:
<OutputConstraints> := <SharedOutput> [<OpticalInterfaceClassList>]


#3 Section 5.3.1
OLD:
      5.3.2. Modulation Type List

      Modulation type, also known as optical tributary signal class,
      comes in two distinct flavors: (i) ITU-T standardized types; (ii)
      vendor specific types. The permitted modulation type list can
      include any mixture of standardized and vendor specific types.

      <modulation-list>::=
      [<STANDARD_MODULATION>|<VENDOR_MODULATION>]...

      Where the STANDARD_MODULATION object just represents one of the
      ITU-T standardized optical tributary signal class and the
      VENDOR_MODULATION object identifies one vendor specific
      modulation type.

      5.3.3. FEC Type List

      Some devices can handle more than one FEC type and hence a list
      is needed.

      <fec-list>::= [<FEC>]

      Where the FEC object represents one of the ITU-T standardized
      FECs defined in [G.709], [G.707], [G.975.1] or a vendor-specific
      FEC.

      5.3.4. Bit Rate Range List

      Some devices can handle more than one particular bit rate range
      and hence a list is needed.

      <rate-range-list>::= [<rate-range>]...

      <rate-range>::=<START_RATE><END_RATE>

      Where the START_RATE object represents the lower end of the range
      and the END_RATE object represents the higher end of the range.



NEW:
    5.3.2 Optical Interface Class List

    <OpticalInterfaceClassList> ::= <OPTICAL_INT_CLASS> ...

    Where the term <OPTICAL_INT_CLASS> is defined by [xyz].



for the info model, That's all folks
Cheers
G

Hi Giovann= i,

I don=A1= =AFt know how many people have reviewed =A1=B0draft-martinelli-wson-interfa= ce-class-02=A1=B1, but I have to admit that I don=A1=AFt understand what pr= oblem this draft is trying to resolve after I reviewed it several times.

 = ;

I guess th= e purpose of the OCI is to use a general format to carry all kinds of the s= ignal compatibility information, is this right?  If my understanding is correct, could you tell how to carry all kinds of the necessary signal = compatibility information instead of simply saying as follows? In another w= ay, could you explain and illustrate how to carry the information defined i= n [G.698.1] and [G.698.2]?

Hi Young,

you are right I did not answer yet...

The question I have for you and Greg is: why you want to go and discuss det= ails about ITU application code internals? Is not enough to state that if t= wo interfaces has the same application code they are compatible?

As already stated, the OIC concept get rid of specific parameters you need = to list to assess signal compatibility so we just leverage what ITU decided= to make compatibility assessment. In term of WSON protocols the we think t= he better solution is to provide room to caary compatibility information but not to go into arguing about i= nternal gory details (we are supposed not to have optical knowledge ;-))

[Fatai] Ho= w to get rid of=A1=AD? We must go into the tech details when we design the = protocol encoding. I don=A1=AFt know how people who are supposed not having optical knowledge design the protocol encoding. <= /p>

As Greg=A1=AFs previous email indicated, the OIC is defined to= represent many fields, some of which are not relevant to WSON signal compa= tibility (for example, S field =3D spectral excursion, W =3D span distance,= z =3D fiber type) and FEC is not defined in OIC. Besides, the WSON signal compatibility needs to include processing ca= pability (e.g., REG capable, and others), which is not defined by the OIC.

 

The co-aut= hors of the WSON info and encoding do not feel that OIC proposal has much r= elevance to the current WSON signal compatibility encoding. We=A1=AFd like to close this issue and move on.

Hi Giovanni, I still don't unde= rstand what problem the "Optical Interface Class" is addressing. = You seem to be replacing something that is well defined "modulation ty= pe" with something less precise, and removing the important detailed FEC type information.

For the non-impairment case in ITU-T G.959.1 where they define various &quo= t;optical tributary signal classes". This is the basis for the "m= odulation type" in the WSON info draft.  In GMPLS WSON extensions= we are not trying to take on the entire management plane we take a minimal subset needed for connection provisioning. Perhaps if we= just rename our "modulation type" to "optical tributary sig= nal class" this will clear up any confusion.  Otherwise we need t= o know more specifically what you think you need added and why you want to remove the FEC type.

ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create &= quot;application codes" which describe link and signal attributes. The= se application codes have the form: DScW-ytz(v) where
    D     indicates DWDM applications  -= -> Why do you need or want this? DWDM and CWDM data planes can't talk, L= MP will tell you this
    S     indicates maximum spectral excursio= n --> Sounds impairment related...
    c     is the channel spacing in GHz -->= ; Wouldn't LMP catch this incompatibility?
    W    is a letter indicating the span dist= ance (S =3D short haul, L long haul) --> This seems like coarse impairme= nt information
    y     indicates the the highest class of = optical tributary signal supported  --> From ITU-T G.959.1, already= have in WG draft.
    t     is a placeholder letter
    z     indicates the fiber type = --> This seems like very coarse grained impairment information.
    v     indicates the operating wavelength = range in terms of spectral bands --> Already have in more detail

We already explicitly support "y" (our more detailed modulation t= ype list) and "v" (we support the more detailed port wavelength c= onstraint explicitly).

Lyndon and other "Optical Interface Class" co-authors in the bay = area, perhaps we can meet and discuss.

Dear WG,

according to input from Lou here the suggested changes on draft-ietf-ccamp-= rwa-info-14  if the Optical Interface Class is used:

#1  Section 5.2
OLD:
<InputConstraints> ::=3D <SharedInput> [<ModulationTypeList&= gt;]
   [<FECTypeList>] [<BitRateRange>] [<ClientSignal= List>]

NEW:
<InputConstraints> ::=3D <SharedInput> [<OpticalInterfaceCla= ssList>] [<ClientSignalList>]


#2 Section 5.2
OLD:
<OutputConstraints> :=3D <SharedOutput> [<ModulationTypeList= >]
   [<FECTypeList>]

NEW:
<OutputConstraints> :=3D <SharedOutput> [<OpticalInterfaceCl= assList>]


#3 Section 5.3.1
OLD:
      5.3.2. Modulation Type List

      Modulation type, also known as optical tribu= tary signal class,
      comes in two distinct flavors: (i) ITU-T sta= ndardized types; (ii)
      vendor specific types. The permitted modulat= ion type list can
      include any mixture of standardized and vend= or specific types.

      <modulation-list>::=3D
      [<STANDARD_MODULATION>|<VENDOR_MODU= LATION>]...

      Where the STANDARD_MODULATION object just re= presents one of the
      ITU-T standardized optical tributary signal = class and the
      VENDOR_MODULATION object identifies one vend= or specific
      modulation type.

      5.3.3. FEC Type List

      Some devices can handle more than one FEC ty= pe and hence a list
      is needed.

      <fec-list>::=3D [<FEC>]

      Where the FEC object represents one of the I= TU-T standardized
      FECs defined in [G.709], [G.707], [G.975.1] = or a vendor-specific
      FEC.

      5.3.4. Bit Rate Range List

      Some devices can handle more than one partic= ular bit rate range
      and hence a list is needed.

      <rate-range-list>::=3D [<rate-range= >]...

      <rate-range>::=3D<START_RATE><= ;END_RATE>

      Where the START_RATE object represents the l= ower end of the range
      and the END_RATE object represents the highe= r end of the range.



NEW:
    5.3.2 Optical Interface Class List

    <OpticalInterfaceClassList> ::=3D <OPTICAL_INT_= CLASS> ...

    Where the term <OPTICAL_INT_CLASS> is defined by [= xyz].

Hi Giovanni, I still don't understand what problem t= he "Optical Interface Class" is addressing. You seem to be replac= ing something that is well defined "modulation type" with somethi= ng less precise, and removing the important detailed FEC type information.

For the non-impairment case in ITU-T G.959.1 where they define various &quo= t;optical tributary signal classes". This is the basis for the "m= odulation type" in the WSON info draft.  In GMPLS WSON extensions= we are not trying to take on the entire management plane we take a minimal subset needed for connection provisioning. Perhaps if we= just rename our "modulation type" to "optical tributary sig= nal class" this will clear up any confusion.  Otherwise we need t= o know more specifically what you think you need added and why you want to remove the FEC type.

ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create &= quot;application codes" which describe link and signal attributes. The= se application codes have the form: DScW-ytz(v) where
    D     indicates DWDM applications  -= -> Why do you need or want this? DWDM and CWDM data planes can't talk, L= MP will tell you this
    S     indicates maximum spectral excursio= n --> Sounds impairment related...

    W    is a letter indicating the span dist= ance (S =3D short haul, L long haul) --> This seems like coarse impairme= nt information
    y     indicates the the highest class of = optical tributary signal supported  --> From ITU-T G.959.1, already= have in WG draft.
    t     is a placeholder letter
    z     indicates the fiber type = --> This seems like very coarse grained impairment information.
    v     indicates the operating wavelength = range in terms of spectral bands --> Already have in more detail

We already explicitly support "y" (our more detailed modulation t= ype list) and "v" (we support the more detailed port wavelength c= onstraint explicitly).

Dear WG,

according to input from Lou here the suggested changes on draft-ietf-ccamp-= rwa-info-14  if the Optical Interface Class is used:

#1  Section 5.2
OLD:
<InputConstraints> ::=3D <SharedInput> [<ModulationTypeList&= gt;]
   [<FECTypeList>] [<BitRateRange>] [<ClientSignal= List>]

NEW:
<InputConstraints> ::=3D <SharedInput> [<OpticalInterfaceCla= ssList>] [<ClientSignalList>]


#2 Section 5.2
OLD:
<OutputConstraints> :=3D <SharedOutput> [<ModulationTypeList= >]
   [<FECTypeList>]

NEW:
<OutputConstraints> :=3D <SharedOutput> [<OpticalInterfaceCl= assList>]


#3 Section 5.3.1
OLD:
      5.3.2. Modulation Type List

      Modulation type, also known as optical tribu= tary signal class,
      comes in two distinct flavors: (i) ITU-T sta= ndardized types; (ii)
      vendor specific types. The permitted modulat= ion type list can
      include any mixture of standardized and vend= or specific types.

      <modulation-list>::=3D
      [<STANDARD_MODULATION>|<VENDOR_MODU= LATION>]...

      Where the STANDARD_MODULATION object just re= presents one of the
      ITU-T standardized optical tributary signal = class and the
      VENDOR_MODULATION object identifies one vend= or specific
      modulation type.

      5.3.3. FEC Type List

      Some devices can handle more than one FEC ty= pe and hence a list
      is needed.

      <fec-list>::=3D [<FEC>]

      Where the FEC object represents one of the I= TU-T standardized
      FECs defined in [G.709], [G.707], [G.975.1] = or a vendor-specific
      FEC.

      5.3.4. Bit Rate Range List

      Some devices can handle more than one partic= ular bit rate range
      and hence a list is needed.

      <rate-range-list>::=3D [<rate-range= >]...

      <rate-range>::=3D<START_RATE><= ;END_RATE>

      Where the START_RATE object represents the l= ower end of the range
      and the END_RATE object represents the highe= r end of the range.



NEW:
    5.3.2 Optical Interface Class List

    <OpticalInterfaceClassList> ::=3D <OPTICAL_INT_= CLASS> ...

    Where the term <OPTICAL_INT_CLASS> is defined by [= xyz].

For signal compatibility we need a certain minimal amount of information which includes modulation type (ITU-T's optical tributary class) and FEC type.

Plus all the specific values for those parameters. Every time ITU define a new FEC type, a new modulation format etc. you need to update all your drafts.

For both of these we provide for vendor specific types so can accommodate any special signals/FECs that you want to define.

That's given I'm not complaining about this (although I would love to state that vendor specific does not means private or hidden).

Can you please explain what problem you are trying to solve and how the current drafts do not address this problem. Please remember these drafts are for the non-impairment case.

The problem is that current draft explicit guess what are the interface parameters needed for signal compatibility. There was a mail a while ago on the mailing list where I did propose changes on draft-ietf-ccamp-rwa-info. I will refresh those info proposing changes on current encoding drafts as well.

Hi Young,

you are right I did not answer yet...

The question I have for you and Greg is: why you want to go and discuss details about ITU application code internals? Is not enough to state that if two interfaces has the same application code they are compatible?

As already stated, the OIC concept get rid of specific parameters you need to list to assess signal compatibility so we just leverage what ITU decided to make compatibility assessment. In term of WSON protocols the we think the better solution is to provide room to caary compatibility information but not to go into arguing about internal gory details (we are supposed not to have optical knowledge ;-))

Hi

 

We haven’t heard any clarification from those who proposed “optical interface classes (OIC) ” to replace the current WSON signal compatibility definition. As Greg’s previous email indicated, the OIC is defined to represent many fields, some of which are not relevant to WSON signal compatibility (for example, S field = spectral excursion, W = span distance, z = fiber type) and FEC is not defined in OIC. Besides, the WSON signal compatibility needs to include processing capability (e.g., REG capable, and others), which is not defined by the OIC.

 

The co-authors of the WSON info and encoding do not feel that OIC proposal has much relevance to the current WSON signal compatibility encoding. We’d like to close this issue and move on.

Young

Hi Giovanni, I still don't understand what problem the "Optical Interface Class" is addressing. You seem to be replacing something that is well defined "modulation type" with something less precise, and removing the important detailed FEC type information.

For the non-impairment case in ITU-T G.959.1 where they define various "optical tributary signal classes". This is the basis for the "modulation type" in the WSON info draft.  In GMPLS WSON extensions we are not trying to take on the entire management plane we take a minimal subset needed for connection provisioning. Perhaps if we just rename our "modulation type" to "optical tributary signal class" this will clear up any confusion.  Otherwise we need to know more specifically what you think you need added and why you want to remove the FEC type.

ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create "application codes" which describe link and signal attributes. These application codes have the form: DScW-ytz(v) where
    D     indicates DWDM applications  --> Why do you need or want this? DWDM and CWDM data planes can't talk, LMP will tell you this
    S     indicates maximum spectral excursion --> Sounds impairment related...
    c     is the channel spacing in GHz --> Wouldn't LMP catch this incompatibility?
    W    is a letter indicating the span distance (S = short haul, L long haul) --> This seems like coarse impairment information
    y     indicates the the highest class of optical tributary signal supported  --> From ITU-T G.959.1, already have in WG draft.
    t     is a placeholder letter
    z     indicates the fiber type  --> This seems like very coarse grained impairment information.
    v     indicates the operating wavelength range in terms of spectral bands --> Already have in more detail

We already explicitly support "y" (our more detailed modulation type list) and "v" (we support the more detailed port wavelength constraint explicitly).

Lyndon and other "Optical Interface Class" co-authors in the bay area, perhaps we can meet and discuss.

Best Regards
Greg B.

Dear WG,

according to input from Lou here the suggested changes on draft-ietf-ccamp-rwa-info-14  if the Optical Interface Class is used:

#1  Section 5.2
OLD:
<InputConstraints> ::= <SharedInput> [<ModulationTypeList>]
   [<FECTypeList>] [<BitRateRange>] [<ClientSignalList>]

NEW:
<InputConstraints> ::= <SharedInput> [<OpticalInterfaceClassList>] [<ClientSignalList>]


#2 Section 5.2
OLD:
<OutputConstraints> := <SharedOutput> [<ModulationTypeList>]
   [<FECTypeList>]

NEW:
<OutputConstraints> := <SharedOutput> [<OpticalInterfaceClassList>]


#3 Section 5.3.1
OLD:
      5.3.2. Modulation Type List

      Modulation type, also known as optical tributary signal class,
      comes in two distinct flavors: (i) ITU-T standardized types; (ii)
      vendor specific types. The permitted modulation type list can
      include any mixture of standardized and vendor specific types.

      <modulation-list>::=
      [<STANDARD_MODULATION>|<VENDOR_MODULATION>]...

      Where the STANDARD_MODULATION object just represents one of the
      ITU-T standardized optical tributary signal class and the
      VENDOR_MODULATION object identifies one vendor specific
      modulation type.

      5.3.3. FEC Type List

      Some devices can handle more than one FEC type and hence a list
      is needed.

      <fec-list>::= [<FEC>]

      Where the FEC object represents one of the ITU-T standardized
      FECs defined in [G.709], [G.707], [G.975.1] or a vendor-specific
      FEC.

      5.3.4. Bit Rate Range List

      Some devices can handle more than one particular bit rate range
      and hence a list is needed.

      <rate-range-list>::= [<rate-range>]...

      <rate-range>::=<START_RATE><END_RATE>

      Where the START_RATE object represents the lower end of the range
      and the END_RATE object represents the higher end of the range.



NEW:
    5.3.2 Optical Interface Class List

    <OpticalInterfaceClassList> ::= <OPTICAL_INT_CLASS> ...

    Where the term <OPTICAL_INT_CLASS> is defined by [xyz].



for the info model, That's all folks
Cheers

Hi Young,

you are right I did not answer yet...

The question I have for you and Greg is: why you want to go and discuss details about ITU application code internals? Is not enough to state that if two interfaces has the same application code they are compatible?

 

YOUNG>> First, the ITU-T application code format defined in G.698.1 and .2 cannot be used in WSON case because it is not complete --- FEC types are not defined in the current field: DScW-ytz(v) which Greg’s email already described each field.

So we cannot borrow its code as is today --- there is no way to check FEC compatibility.

[GM] I guess my view is within the other email. Instead of looking at ITU application code internals we make this question: two interfaces having the same application code are compatible?
My answer is yes...

 

Beside, In signal compatibility, we have other fields we are checking such as processing capability (see section 5.6 http://datatracker.ietf.org/doc/draft-ietf-ccamp-rwa-wson-encode/?include_text=1) --- such as reg capability, monitoring and any vendor specific capability).

 

I would keep the signal compatibility separated from processing capability. As suggested by Lou I would send an email with proposed changes on the draft you mention (I did only on info model, encoding changes comes easily but better to highlight)

Cheers
G



More fundamentally, the application code points in the current G.698.1 and .2 were defined in the context of DWDM black links and optical impairment context. As such many data are not relevant to the current WSON non-impairment scope.

 

 

 

 



As already stated, the OIC concept get rid of specific parameters you need to list to assess signal compatibility so we just leverage what ITU decided to make compatibility assessment. In term of WSON protocols the we think the better solution is to provide room to caary compatibility information but not to go into arguing about internal gory details (we are supposed not to have optical knowledge ;-))


Cheers

Hi

 

We haven’t heard any clarification from those who proposed “optical interface classes (OIC) ” to replace the current WSON signal compatibility definition. As Greg’s previous email indicated, the OIC is defined to represent many fields, some of which are not relevant to WSON signal compatibility (for example, S field = spectral excursion, W = span distance, z = fiber type) and FEC is not defined in OIC. Besides, the WSON signal compatibility needs to include processing capability (e.g., REG capable, and others), which is not defined by the OIC.

 

The co-authors of the WSON info and encoding do not feel that OIC proposal has much relevance to the current WSON signal compatibility encoding. We’d like to close this issue and move on.

 

Regards,

Young

Hi Giovanni, I still don't understand what problem the "Optical Interface Class" is addressing. You seem to be replacing something that is well defined "modulation type" with something less precise, and removing the important detailed FEC type information.

For the non-impairment case in ITU-T G.959.1 where they define various "optical tributary signal classes". This is the basis for the "modulation type" in the WSON info draft.  In GMPLS WSON extensions we are not trying to take on the entire management plane we take a minimal subset needed for connection provisioning. Perhaps if we just rename our "modulation type" to "optical tributary signal class" this will clear up any confusion.  Otherwise we need to know more specifically what you think you need added and why you want to remove the FEC type.

ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create "application codes" which describe link and signal attributes. These application codes have the form: DScW-ytz(v) where
    D     indicates DWDM applications  --> Why do you need or want this? DWDM and CWDM data planes can't talk, LMP will tell you this
    S     indicates maximum spectral excursion --> Sounds impairment related...
    c     is the channel spacing in GHz --> Wouldn't LMP catch this incompatibility?
    W    is a letter indicating the span distance (S = short haul, L long haul) --> This seems like coarse impairment information
    y     indicates the the highest class of optical tributary signal supported  --> From ITU-T G.959.1, already have in WG draft.
    t     is a placeholder letter
    z     indicates the fiber type  --> This seems like very coarse grained impairment information.
    v     indicates the operating wavelength range in terms of spectral bands --> Already have in more detail

We already explicitly support "y" (our more detailed modulation type list) and "v" (we support the more detailed port wavelength constraint explicitly).

Lyndon and other "Optical Interface Class" co-authors in the bay area, perhaps we can meet and discuss.

Best Regards
Greg B.

Dear WG,

according to input from Lou here the suggested changes on draft-ietf-ccamp-rwa-info-14  if the Optical Interface Class is used:

#1  Section 5.2
OLD:
<InputConstraints> ::= <SharedInput> [<ModulationTypeList>]
   [<FECTypeList>] [<BitRateRange>] [<ClientSignalList>]

NEW:
<InputConstraints> ::= <SharedInput> [<OpticalInterfaceClassList>] [<ClientSignalList>]


#2 Section 5.2
OLD:
<OutputConstraints> := <SharedOutput> [<ModulationTypeList>]
   [<FECTypeList>]

NEW:
<OutputConstraints> := <SharedOutput> [<OpticalInterfaceClassList>]


#3 Section 5.3.1
OLD:
      5.3.2. Modulation Type List

      Modulation type, also known as optical tributary signal class,
      comes in two distinct flavors: (i) ITU-T standardized types; (ii)
      vendor specific types. The permitted modulation type list can
      include any mixture of standardized and vendor specific types.

      <modulation-list>::=
      [<STANDARD_MODULATION>|<VENDOR_MODULATION>]...

      Where the STANDARD_MODULATION object just represents one of the
      ITU-T standardized optical tributary signal class and the
      VENDOR_MODULATION object identifies one vendor specific
      modulation type.

      5.3.3. FEC Type List

      Some devices can handle more than one FEC type and hence a list
      is needed.

      <fec-list>::= [<FEC>]

      Where the FEC object represents one of the ITU-T standardized
      FECs defined in [G.709], [G.707], [G.975.1] or a vendor-specific
      FEC.

      5.3.4. Bit Rate Range List

      Some devices can handle more than one particular bit rate range
      and hence a list is needed.

      <rate-range-list>::= [<rate-range>]...

      <rate-range>::=<START_RATE><END_RATE>

      Where the START_RATE object represents the lower end of the range
      and the END_RATE object represents the higher end of the range.



NEW:
    5.3.2 Optical Interface Class List

    <OpticalInterfaceClassList> ::= <OPTICAL_INT_CLASS> ...

    Where the term <OPTICAL_INT_CLASS> is defined by [xyz].



for the info model, That's all folks
Cheers

Hi Giovanni,

 

I don’t know how many people have reviewed “draft-martinelli-wson-interface-class-02”, but I have to admit that I don’t understand what problem this draft is trying to resolve after I reviewed it several times.


[GM] assuming you well know how current wson draft deals with the signal compatibility I'm not sure about your statement here above...


 

I guess the purpose of the OCI is to use a general format to carry all kinds of the signal compatibility information, is this right?


[GM] yes


 If my understanding is correct, could you tell how to carry all kinds of the necessary signal compatibility information instead of simply saying as follows? In another way, could you explain and illustrate how to carry the information defined in [G.698.1] and [G.698.2]?


[GM] In current draft the only requirement to assess the signal compatibility is  that two interface having the same OIC value are compatible. So WSON protocols does not need to explicitly list optical parameters and their value. We can probably provide some examples in an appendix about how you can map them but the OIC concept per se does not depend on this.

Hi Young,

you are right I did not answer yet...

The question I have for you and Greg is: why you want to go and discuss details about ITU application code internals? Is not enough to state that if two interfaces has the same application code they are compatible?

As already stated, the OIC concept get rid of specific parameters you need to list to assess signal compatibility so we just leverage what ITU decided to make compatibility assessment. In term of WSON protocols the we think the better solution is to provide room to caary compatibility information but not to go into arguing about internal gory details (we are supposed not to have optical knowledge ;-))

[Fatai] How to get rid of…? We must go into the tech details when we design the protocol encoding. I don’t know how people who are supposed not having optical knowledge design the protocol encoding.

Hi

 

We haven’t heard any clarification from those who proposed “optical interface classes (OIC) ” to replace the current WSON signal compatibility definition. As Greg’s previous email indicated, the OIC is defined to represent many fields, some of which are not relevant to WSON signal compatibility (for example, S field = spectral excursion, W = span distance, z = fiber type) and FEC is not defined in OIC. Besides, the WSON signal compatibility needs to include processing capability (e.g., REG capable, and others), which is not defined by the OIC.

 

The co-authors of the WSON info and encoding do not feel that OIC proposal has much relevance to the current WSON signal compatibility encoding. We’d like to close this issue and move on.

Young

Hi Giovanni, I still don't understand what problem the "Optical Interface Class" is addressing. You seem to be replacing something that is well defined "modulation type" with something less precise, and removing the important detailed FEC type information.

For the non-impairment case in ITU-T G.959.1 where they define various "optical tributary signal classes". This is the basis for the "modulation type" in the WSON info draft.  In GMPLS WSON extensions we are not trying to take on the entire management plane we take a minimal subset needed for connection provisioning. Perhaps if we just rename our "modulation type" to "optical tributary signal class" this will clear up any confusion.  Otherwise we need to know more specifically what you think you need added and why you want to remove the FEC type.

ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create "application codes" which describe link and signal attributes. These application codes have the form: DScW-ytz(v) where
    D     indicates DWDM applications  --> Why do you need or want this? DWDM and CWDM data planes can't talk, LMP will tell you this
    S     indicates maximum spectral excursion --> Sounds impairment related...
    c     is the channel spacing in GHz --> Wouldn't LMP catch this incompatibility?
    W    is a letter indicating the span distance (S = short haul, L long haul) --> This seems like coarse impairment information
    y     indicates the the highest class of optical tributary signal supported  --> From ITU-T G.959.1, already have in WG draft.
    t     is a placeholder letter
    z     indicates the fiber type  --> This seems like very coarse grained impairment information.
    v     indicates the operating wavelength range in terms of spectral bands --> Already have in more detail

We already explicitly support "y" (our more detailed modulation type list) and "v" (we support the more detailed port wavelength constraint explicitly).

Lyndon and other "Optical Interface Class" co-authors in the bay area, perhaps we can meet and discuss.

Best Regards
Greg B.

Dear WG,

according to input from Lou here the suggested changes on draft-ietf-ccamp-rwa-info-14  if the Optical Interface Class is used:

#1  Section 5.2
OLD:
<InputConstraints> ::= <SharedInput> [<ModulationTypeList>]
   [<FECTypeList>] [<BitRateRange>] [<ClientSignalList>]

NEW:
<InputConstraints> ::= <SharedInput> [<OpticalInterfaceClassList>] [<ClientSignalList>]


#2 Section 5.2
OLD:
<OutputConstraints> := <SharedOutput> [<ModulationTypeList>]
   [<FECTypeList>]

NEW:
<OutputConstraints> := <SharedOutput> [<OpticalInterfaceClassList>]


#3 Section 5.3.1
OLD:
      5.3.2. Modulation Type List

      Modulation type, also known as optical tributary signal class,
      comes in two distinct flavors: (i) ITU-T standardized types; (ii)
      vendor specific types. The permitted modulation type list can
      include any mixture of standardized and vendor specific types.

      <modulation-list>::=
      [<STANDARD_MODULATION>|<VENDOR_MODULATION>]...

      Where the STANDARD_MODULATION object just represents one of the
      ITU-T standardized optical tributary signal class and the
      VENDOR_MODULATION object identifies one vendor specific
      modulation type.

      5.3.3. FEC Type List

      Some devices can handle more than one FEC type and hence a list
      is needed.

      <fec-list>::= [<FEC>]

      Where the FEC object represents one of the ITU-T standardized
      FECs defined in [G.709], [G.707], [G.975.1] or a vendor-specific
      FEC.

      5.3.4. Bit Rate Range List

      Some devices can handle more than one particular bit rate range
      and hence a list is needed.

      <rate-range-list>::= [<rate-range>]...

      <rate-range>::=<START_RATE><END_RATE>

      Where the START_RATE object represents the lower end of the range
      and the END_RATE object represents the higher end of the range.



NEW:
    5.3.2 Optical Interface Class List

    <OpticalInterfaceClassList> ::= <OPTICAL_INT_CLASS> ...

    Where the term <OPTICAL_INT_CLASS> is defined by [xyz].



for the info model, That's all folks
Cheers

ITU application does *not only* deal with impairments, for sure they deal with some other physical parameters and they *guarantee* wson interfaces compatibility (which is our current sub-case).
I'm wondering  we need some official statement from from ITU on this topic through the usual communication flows ccamp has with ITU (but I guess thisi to wg chairs to decide). 

From CCAMP side, I would say that draft are not related to impairments but I would prefer a solution that will simplify both problems: RWA only (i.e. signal compatibility), RWA-IV (signal compatibility + some others parmeters).

Keep in mind that ITU application code is one instance of the optical interface class. The OIC per-se is a container and draft-martinelli-wson-interface-class-02 propose how the ITU application can map on the OIC .

 
For signal compatibility we need a certain minimal amount of information which includes modulation type (ITU-T's optical tributary class) and FEC type.

Plus all the specific values for those parameters. Every time ITU define a new FEC type, a new modulation format etc. you need to update all your drafts.

For both of these we provide for vendor specific types so can accommodate any special signals/FECs that you want to define.

That's given I'm not complaining about this (although I would love to state that vendor specific does not means private or hidden).

Can you please explain what problem you are trying to solve and how the current drafts do not address this problem. Please remember these drafts are for the non-impairment case.

The problem is that current draft explicit guess what are the interface parameters needed for signal compatibility. There was a mail a while ago on the mailing list where I did propose changes on draft-ietf-ccamp-rwa-info. I will refresh those info proposing changes on current encoding drafts as well.

Hi Young,

you are right I did not answer yet...

The question I have for you and Greg is: why you want to go and discuss details about ITU application code internals? Is not enough to state that if two interfaces has the same application code they are compatible?

As already stated, the OIC concept get rid of specific parameters you need to list to assess signal compatibility so we just leverage what ITU decided to make compatibility assessment. In term of WSON protocols the we think the better solution is to provide room to caary compatibility information but not to go into arguing about internal gory details (we are supposed not to have optical knowledge ;-))

Hi

 

We haven’t heard any clarification from those who proposed “optical interface classes (OIC) ” to replace the current WSON signal compatibility definition. As Greg’s previous email indicated, the OIC is defined to represent many fields, some of which are not relevant to WSON signal compatibility (for example, S field = spectral excursion, W = span distance, z = fiber type) and FEC is not defined in OIC. Besides, the WSON signal compatibility needs to include processing capability (e.g., REG capable, and others), which is not defined by the OIC.

 

The co-authors of the WSON info and encoding do not feel that OIC proposal has much relevance to the current WSON signal compatibility encoding. We’d like to close this issue and move on.

Young

Hi Giovanni, I still don't understand what problem the "Optical Interface Class" is addressing. You seem to be replacing something that is well defined "modulation type" with something less precise, and removing the important detailed FEC type information.

For the non-impairment case in ITU-T G.959.1 where they define various "optical tributary signal classes". This is the basis for the "modulation type" in the WSON info draft.  In GMPLS WSON extensions we are not trying to take on the entire management plane we take a minimal subset needed for connection provisioning. Perhaps if we just rename our "modulation type" to "optical tributary signal class" this will clear up any confusion.  Otherwise we need to know more specifically what you think you need added and why you want to remove the FEC type.

ITU-T G.698.1 and G.698.2 reference G.959.1 and other documents to create "application codes" which describe link and signal attributes. These application codes have the form: DScW-ytz(v) where
    D     indicates DWDM applications  --> Why do you need or want this? DWDM and CWDM data planes can't talk, LMP will tell you this
    S     indicates maximum spectral excursion --> Sounds impairment related...
    c     is the channel spacing in GHz --> Wouldn't LMP catch this incompatibility?
    W    is a letter indicating the span distance (S = short haul, L long haul) --> This seems like coarse impairment information
    y     indicates the the highest class of optical tributary signal supported  --> From ITU-T G.959.1, already have in WG draft.
    t     is a placeholder letter
    z     indicates the fiber type  --> This seems like very coarse grained impairment information.
    v     indicates the operating wavelength range in terms of spectral bands --> Already have in more detail

We already explicitly support "y" (our more detailed modulation type list) and "v" (we support the more detailed port wavelength constraint explicitly).

Lyndon and other "Optical Interface Class" co-authors in the bay area, perhaps we can meet and discuss.

Best Regards
Greg B.

Dear WG,

according to input from Lou here the suggested changes on draft-ietf-ccamp-rwa-info-14  if the Optical Interface Class is used:

#1  Section 5.2
OLD:
<InputConstraints> ::= <SharedInput> [<ModulationTypeList>]
   [<FECTypeList>] [<BitRateRange>] [<ClientSignalList>]

NEW:
<InputConstraints> ::= <SharedInput> [<OpticalInterfaceClassList>] [<ClientSignalList>]


#2 Section 5.2
OLD:
<OutputConstraints> := <SharedOutput> [<ModulationTypeList>]
   [<FECTypeList>]

NEW:
<OutputConstraints> := <SharedOutput> [<OpticalInterfaceClassList>]


#3 Section 5.3.1
OLD:
      5.3.2. Modulation Type List

      Modulation type, also known as optical tributary signal class,
      comes in two distinct flavors: (i) ITU-T standardized types; (ii)
      vendor specific types. The permitted modulation type list can
      include any mixture of standardized and vendor specific types.

      <modulation-list>::=
      [<STANDARD_MODULATION>|<VENDOR_MODULATION>]...

      Where the STANDARD_MODULATION object just represents one of the
      ITU-T standardized optical tributary signal class and the
      VENDOR_MODULATION object identifies one vendor specific
      modulation type.

      5.3.3. FEC Type List

      Some devices can handle more than one FEC type and hence a list
      is needed.

      <fec-list>::= [<FEC>]

      Where the FEC object represents one of the ITU-T standardized
      FECs defined in [G.709], [G.707], [G.975.1] or a vendor-specific
      FEC.

      5.3.4. Bit Rate Range List

      Some devices can handle more than one particular bit rate range
      and hence a list is needed.

      <rate-range-list>::= [<rate-range>]...

      <rate-range>::=<START_RATE><END_RATE>

      Where the START_RATE object represents the lower end of the range
      and the END_RATE object represents the higher end of the range.



NEW:
    5.3.2 Optical Interface Class List

    <OpticalInterfaceClassList> ::= <OPTICAL_INT_CLASS> ...

    Where the term <OPTICAL_INT_CLASS> is defined by [xyz].



for the info model, That's all folks
Cheers

OSPF-TE is already advertising the SRLGs associated with each TE-link (AFAIK= this includes LSPs that are modeled as TE-links). So each node in the netwo= rk already has the information on the set of SRLGs a TE link belongs to. Each node can compute a path through the network and the path would typicall= y be computed using a path computation algorithm that uses the topology info= rmation distributed by OSPF-TE (or any other equivalent routing protocol). O= nce the path is computed (source routing), then the TE-links used by the pat= h is known at the head-end. Once TE-links are known, SRLG information is als= o known (from above). So where does the need to carry the SRLG info the RROs arise?

Hi Giovann= i,

 = ;

<snippe= d>


[GM] In current draft the only requirement to assess the signal compatibili= ty is  that two interface having the same OIC value are compatible. So= WSON protocols does not need to explicitly list optical parameters and the= ir value. We can probably provide some examples in an appendix about how you can map them but the OIC concept per= se does not depend on this.

[Fatai] How magic the OIC i= s. I really want to see how this magic would happen if there is no need to list optical parameters and their value. <= /p>

 


Cheers
G

Thanks
