If yes, it would be good to mention it. The = document states requirements multiple times. Abstract : The abstract is really short, would be good to enhance it with what is exac= tly described. In Section 1, there should be an issue with the XML file as the hypertext l= ink is missing at : "We discuss two different approaches to provide ..., in= Section 3". Hyperlink missing for "Section 3". In Section 2, It would be good to state in the example that the paths must not be protect= ed by any local repair techniques. Example : "The two paths are made disjoi= nt using the SPRING architecture and must not be protected by any local rep= air techniques". As a requirement, the two paths must be disjoint (link or node, or srlg), t= his has some impacts on the path expression : using a node-SID would be a b= ad idea as there is no guarantee. It would be good to mention that the solu= tion must take care of this. It would be easier to state that path T1 is primary and T2 is backup instea= d of : "When T1 is up, the packets of the PW are sent on T1". Why not using the following text : "T1 is programmed as primary forwarding entry while T2 is a backup entry. I= n nominal state, PW traffic is carried over T1. When T1 fails, the PW traff= ic is switched on T2". Before telling that the solution for end-to-end liveness is out of scope, i= t would be good to state that it is mandatory to have such mechanism to mak= e the solution work. Is it a SPRING path liveness check or service liveness= check ? It would be good to tell who is in charge of the detection and pa= th switchover ? is it LSP ingress, is it a node outside SPRING network ? If= there are multiple options, please tell it. I would propose to change the last sentence to highlight the two requiremen= ts in case we need SPRING path liveness check : "From a SPRING viewpoint, the SPRING architecture MUST provide end-to-end l= iveness check of SPRING based LSPs. In addition, it MUST provide a way to c= reate LSPs that must not be protected by local repair techniques." Globally this section looks confusing to me. End to end protection could be= achieved in multiple ways, for example : - Having a dumb network that only provides disjoint non protected path and = having end-to-end probes at service level that would help an external compo= nent to switchover traffic. Provider network is not aware of the protection= done. In your figure we can add A' and Z', and we establish two disjoint L= SPs (A->Z and A'->Z'). Customer is dual meshed to A/A' and Z/Z' and is mana= ging liveness check and switchover (network is not involved). - Having primary/backup like approach : two disjoint LSPs from A->Z , A pro= grams one in FIB. A provides OAM on the LSP. When primary LSP fails, the se= cond one is installed in FIB. - Having FRR like approach : two disjoint LSPs from A->Z , A programs both = in FIB in a FRR like fashion. A provides aggressive OAM on the LSPs to enab= le traffic switchover in a very short time. The current text is not really clear on the proposed approach. Maybe anothe= r one ? Section 3 s/the backup path computation should/the backup path computation SHOULD/ s/in any topology/in any topology./ s/by the IGP/by the IGP./ Section 3.1 "ending at the protected nexthop", that's true only for link protection, bu= t not possible in case of node protection. This sentence is a generic one a= nd is not specific to link protection case. I cannot parse : "so as to bypass the failed component ..." I would propose something like : "One way to provide local repair is to enforce a failover along the shortes= t path around the protected component. In case of link protection, the poi= nt of local repair will create a bypass avoiding the protected link and mer= ging back to primary path at the nexthop. In case of node protection, the b= ypass will avoid the protected node and merge back to primary path at the n= ext-nexthop." What about SRLG case ? "In our example, C protects Z", protects for what ? link / node /srlg failu= re ? proposed text : "In our example, C protects destination Z for a failur= e CD link" "that it initially reaches via CD", yes and also using CH because of ECMP, = it would be better to change the example to disable ECMP. There are multipl= e ECMPs that would not help the reading. Even A as ECMP to Z. Section 3.2 "providing a repair for the destination based on shortest path state for th= at destination". Why using "state" ? Again : "In our example, C protects Z", protects for what ? link / node /sr= lg failure ? You have again ECMP starting from A, and at other nodes that complexifies t= he example. Why not talking about pros/cons between approaches ? Section 4. SRLG was mentioned as a requirement in Section 3. So why considering it as = a more high level constraint ? If SRLG is management-free, please change your example with another constra= int type (bandwidth for example). You can refer to RFC7916 as an example of managed computation. Similar appr= oach can be used here. Section 4.1 Is the path {CG,GH,HD} computed automatically or putted manually ? Please b= e clear on what must be done. Section 4.2 This case is a bit strange. The goal is to use shortest path protection to = the destination but here we enforce a non shortest path, so the name is no = more applicable. It is more a per-destination protection tweaking. Again ho= w is it done, configured manually per destination or group of destinations = ? Do you have requirements here ? Section 5 First sentence is hard to read (it works but hard to read). Is it possible = to make it simpler ? For example, "when a topology change occurs in a netwo= rk, transient inconsistencies of router FIBs can occur." Could you point to relevant RFCs/drafts on microloops to help readers that = are interested by more information on the subject. You could tell that those micro-loops are breaking local repair techniques = preventing 50msec restoration. Could you provide an example on how SPRING can prevent loops ? (as you done= for protection cases) Section 6. Could you rename the title to be more explicit : co-existence of what ? Section 8. You also provide requirements, and you have example of manageability requir= ements (revert ability for path protection, managed path) ... Please state clearly that the manageability requirements provided in this d= ocument must be addressed by the solution documents. Could you summarize th= e manageability requirements here ?

Subject: [spring] Shepherd review of draft-oetf-spring-resiliency-us= e-cases

 

Hi,

 

I have been selected as Shepherd for this document, = and as part of my review I have several comments that you will find below :=

 

General :

Is it a requirement document ? If yes, it would be g= ood to mention it. The document states requirements multiple times.

 

 

Abstract :

The abstract is really short, would be good to enhan= ce it with what is exactly described.

 

In Section 1, there should be an issue with the XML = file as the hypertext link is missing at : “We discuss two different = approaches to provide …, in Section 3”. Hyperlink missing for &= #8220;Section 3”.

 

In Section 2,

It would be good to state in the example that the pa= ths must not be protected by any local repair techniques. Example : “= The two paths are made disjoint using the SPRING architecture and must not = be protected by any local repair techniques”.

 

As a requirement, the two paths must be disjoint (li= nk or node, or srlg), this has some impacts on the path expression : using = a node-SID would be a bad idea as there is no guarantee. It would be good t= o mention that the solution must take care of this.

 

It would be easier to state that path T1 is primary = and T2 is backup instead of : “When T1 is  up, the packets of th= e PW are sent on T1”.

Why not using the following text :

“T1 is programmed as primary forwarding entry = while T2 is a backup entry. In nominal state, PW traffic is carried over T1= . When T1 fails, the PW traffic is switched on T2”.

Before telling that the solution for end-to-end live= ness is out of scope, it would be good to state that it is mandatory to hav= e such mechanism to make the solution work. Is it a SPRING path liveness ch= eck or service liveness check ?  It would be good to tell who is in charge of the detection and path switchove= r ? is it LSP ingress, is it a node outside SPRING network ? If there are m= ultiple options, please tell it.

 

I would propose to change the last sentence to highl= ight the two requirements in case we need SPRING path liveness check :=

“From a SPRING viewpoint, the SPRING architect= ure MUST provide end-to-end liveness check of SPRING based LSPs. In additio= n, it MUST provide a way to create LSPs that must not be protected by local= repair techniques.”

 

Globally this section looks confusing to me. End to = end protection could be achieved in multiple ways, for example :=

- Having a dumb network that only provides disjoint = non protected path and having end-to-end probes at service level that would= help an external component to switchover traffic. Provider network is not = aware of the protection done. In your figure we can add A’ and Z’, and we establish two disjoint LSP= s (A->Z and A’->Z’). Customer is dual meshed to A/A’= ; and Z/Z’ and is managing liveness check and switchover (network is = not involved).

- Having primary/backup like approach : two disjoint= LSPs from A->Z , A programs one in FIB. A provides OAM on the LSP. When= primary LSP fails, the second one is installed in FIB.

- Having FRR like approach : two disjoint LSPs from = A->Z , A programs both in FIB in a FRR like fashion. A provides aggressi= ve OAM on the LSPs to enable traffic switchover in a very short time.<= /o:p>

 

The current text is not really clear on the proposed= approach. Maybe another one ?

 

 

Section 3

s/the backup path computation should/the backup path= computation SHOULD/

s/in any topology/in any topology./

s/by the IGP/by the IGP./

 

Section 3.1

“ending at the protected nexthop”, that&= #8217;s true only for link protection, but not possible in case of node pro= tection. This sentence is a generic one and is not specific to link protect= ion case.

I cannot parse : “so as to bypass the failed c= omponent …”

I would propose something like :

“One way to provide local repair is to enforce= a failover along the shortest path around the protected component. In case= of link protection,  the point of local repair will create a bypass a= voiding the protected link and merging back to primary path at the nexthop. In case of node protection, the bypass will a= void the protected node and merge back to primary path at the next-nexthop.= ”

What about SRLG case ?

 

“In our example, C protects Z”, protects= for what ? link / node /srlg failure ? proposed text : “In our examp= le, C protects destination Z for a failure CD link”

 

“that it initially= reaches via CD”, yes and also using CH because of ECMP, it would be = better to change the example to disable ECMP. There are multiple ECMPs that= would not help the reading. Even A as ECMP to Z.

 =

 =

Section 3.2

“providing a repai= r for the destination based on shortest path state for that destinationR= 21;. Why using “state” ?

Again : “In= our example, C protects Z”, protects for what ? link / node /srlg fa= ilure ?

 

You have again ECMP starting from A, and at other no= des that complexifies the example.

 

Why not talking about pros/cons between approaches ?=

 

 

Section 4.

SRLG was mentioned as a requirement in Section 3. So= why considering it as a more high level constraint ?

If SRLG is management-free, please change your examp= le with another constraint type (bandwidth for example).

You can refer to RFC7916 as an example of managed co= mputation. Similar approach can be used here.

 

Section 4.1

Is the path {CG,GH,HD} computed automatically or put= ted manually ? Please be clear on what must be done.

 

Section 4.2

This case is a bit strange. The goal is to use short= est path protection to the destination but here we enforce a non shortest p= ath, so the name is no more applicable. It is more a per-destination protec= tion tweaking. Again how is it done, configured manually per destination or group of destinations ? Do you have= requirements here ?

 

Section 5

First sentence is hard to read (it works but hard to= read). Is it possible to make it simpler ? For example, “when a topo= logy change occurs in a network, transient inconsistencies of router FIBs c= an occur.”

Could you point to relevant RFCs/drafts on microloop= s to help readers that are interested by more information on the subject.

 

You could tell that those micro-loops are breaking l= ocal repair techniques preventing 50msec restoration.

 

Could you provide an example on how SPRING can preve= nt loops ? (as you done for protection cases)

 

Section 6.

Could you rename the title to be more explicit : co-= existence of what ?

 

Section 8.

You also provide requirements, and you have example = of manageability requirements (revert ability for path protection, managed = path) …

Please state clearly that the manageability requirem= ents provided in this document must be addressed by the solution documents.= Could you summarize the manageability requirements here ?

This draft provide a way of how to use SR to scale MPLS network. It is NOT about restrict what operators should do.

Thanks, Chris -----Original Message----- From: spring [mailto:spring-bounces@ietf.org] On Behalf Of Chris Bowers Sent: Wednesday, August 3, 2016 9:24 AM To: spring@ietf.org Subject: [spring] clarification of text in draft-ietf-spring-segment-routin= g-09 SPRING WG, The following paragraph in section 3.2.1 of draft-ietf-spring-segment-routi= ng-09 is confusing. The ingress node of an SR domain validates that the path to a prefix, advertised with a given algorithm, includes nodes all supporting the advertised algorithm. In other words, when computing paths for a given algorithm, the transit nodes MUST compute the algorithm X on the IGP topology, regardless of the support of the algorithm X by the nodes in that topology. As a consequence, if a node on the path does not support algorithm X, the IGP-Prefix segment will be interrupted and will drop packet on that node. It's the responsibility of the ingress node using a segment to check that all downstream nodes support the algorithm of the segment. I interpret the first, third, and fourth sentences in this paragraph as say= ing that an ingress node should make sure that transit nodes on a path inst= all transit forwarding entries for prefix-SIDs for a given algorithm by loo= king that=20 the SR-Algorithm (sub)-TLV advertised by the transit nodes before sending t= raffic on that path. =20 However, the second sentence in the paragraph confuses this interpretation.= =20 "In other words, when computi= ng paths for a given algorithm, the transit nodes MUST compute the algorithm X on the IGP topology, regardless of the support of the algorithm X by the nodes in that topology." This sentence could be interpreted as saying that transit nodes must comput= e all algorithms advertised by any node in the topology, even if the transi= t node doesn't support the algorithm. This sentence doesn't make sense to = me.=20 A simple solution would be to delete this second sentence. However, other = clarifying text would be another solution.

This draft is a work item of the Source Packet Routing in Networking of the IETF. Title : Segment Routing Centralized BGP Peer Engineering Authors : Clarence Filsfils Stefano Previdi Ebben Aries Daniel Ginsburg Dmitry Afanasiev Filename : draft-ietf-spring-segment-routing-central-epe-02.txt Pages : 18 Date : 2016-09-13 Abstract: Segment Routing (SR) leverages source routing. A node steers a packet through a controlled set of instructions, called segments, by prepending the packet with an SR header. A segment can represent any instruction topological or service-based. SR allows to enforce a flow through any topological path and service chain while maintaining per-flow state only at the ingress node of the SR domain. The Segment Routing architecture can be directly applied to the MPLS dataplane with no change on the forwarding plane. It requires minor extension to the existing link-state routing protocols. This document illustrates the application of Segment Routing to solve the BGP Peer Engineering (BGP-PE) requirement. The SR-based BGP-PE solution allows a centralized (SDN) controller to program any egress peer policy at ingress border routers or at hosts within the domain.

Stefano, Chris and all,
I have to admit that I am complete= ly confused:
  &= nbsp;- to the best of my understanding, Chris has asked whether a policy tha= t puts a limit on max. number of ECMP next hops is not compatible with the S= trict SPF algorithm
&= nbsp;  - Stefano says that "Yes, this policy is a good example when Str= ict SPF algorithm can be advertised".

SPRING WG,
The current text in draft-ietf-spring-segment-routing-09 regarding= the
"Strict Shortest Path" algorithm reads as follows.

 o  "Strict Shortest Path": T= his algorithm mandates that the packet is
  &nb= sp; forwarded according to ECMP-aware SPF algorithm and instruct any
    router in the path to ignore any po= ssible local policy overriding
    SP= F decision.  The SID advertised with "Strict Shortest Path"
<= /blockquote>
    algorithm ensures that the path the packet i= s going to take is the
    expected, an= d not altered, SPF path.

One example of= a local policy that overrides the ECMP-aware SPF
algorit= hm decision is a limit on the number of ECMP next-hops.  The
text above implies that if a router places any limit on the number o= f
ECMP forwarding next-hops then it would be wrong for it= to advertise the =E2=80=9CStrict Shortest Path=E2=80=9D algorithm capabilit= y.

Is this the intended interpretation?<= /span>
<= br>

well, yes. Your example is a good one for the =E2= =80=9Cstrict-SPF=E2=80=9D behavior.

s.

If not, what is the i= ntended interpretation?

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 22 Sep 2016 14:53:55 -0000 Hi Stefano, Thanks for the explanation, I have got a bit of different view on the use o= f algorithm logic.=20 PBR is orthogonal to what an IGP does and IMO its presence should not be si= gnaled. More logical would be to use 0 when only metric is taking into consideratio= n when computing a path and other value otherwise, which is indeed deviation= from the strict-SPF. Please let me know what you think. =20 Cheers, Jeff =20 On 9/22/16, 06:57, "Stefano Previdi (sprevidi)" wrote: =20 > On Sep 19, 2016, at 3:28 PM, Alexander Vainshtein wrote: >=20 > Stefano, > I think life would be simpler if you could provide a meaningful examp= le of behavior that is "SPF" (defined as the default algorithm) but not "St= rict SPF=E2=80=9D. =20 =20 algorithm 0 is what you use by default. You compute your=20 segment list with SIDs representing segments which are=20 portion of shortest paths. However, you don=E2=80=99t know if in=20 each node along the path you computed the behavior is=20 exactly the one you intended. =20 Strict-SPF allows you to be sure that the path you=20 computed (and instantiated into a segment list) is=20 exactly what each node will honor. =20 Here=E2=80=99s an example:=20 =20 Assume following topology: . AG and GF links have metric of 20 . All other links have metric of 10 =20 _________G_________ | | A---B---C---D---E---F---Z | | H---I---J =20 . Shortest path from A to Z is AGFZ. . There=E2=80=99s a policy in router A in order to send traffic to Z through the desired path: ABCDEFZ. The reason could be a better delay . Router A computes the path using its LSDB. We assume that TE metric is available in the LSDB and representing the delay of each link so to allow router A to compute a delay-based shortest path. . Router A figures out that it needs segment list EZ in order to steer traffic along ABCDEFZ path. . Router A sends traffic with segment list (label stack): EZ . Now, assume router E has also a local policy in order to send traffic to Z through the desired path: EHIJZ. This may be due to some BW constraint that instructs router E to split part of the traffic towards a different path. . Therefore, router E imposes segment list (label stack) IZ to traffic for Z. . When a packet sent by A (with label stack EZ) arrives in E, the label stack is now Z and router E swaps it with IZ . Now the packet travels through path EHIJZ while router A _thinks_ the packet would travel through path ABCDEFZ. =20 Therefore, there=E2=80=99s a need for router A to instruct any router in the path NOT to alter the shape of the path that router A initially computed for that packet. =20 Strict-SPF SID will do the job. A compliant implementation will install the Strict-SPF SID and nexthop regardless any local policy for that prefix. =20 Now, regarding the ECMP use case, given that ECMP limitations=20 still result in the use of paths all of which are IGP=20 shortest-paths such limitations do not violate the definition=20 of strict-spf behavior. =20 Hope this helps. =20 s. =20 =20 =20 >=20 > IMHO and FWIW Chris has tried to make such an example, but it does no= t look as valid to some people (me included).=20 >=20 > Without any such examples it is not clear why the "Strict SPF" algori= thm is needed. >=20 > Regards, > Sasha >=20 > Office: +972-39266302 > Cell: +972-549266302 > Email: Alexander.Vainshtein@ecitele.com >=20 >=20 > -----Original Message----- > From: Stefano Previdi (sprevidi) [mailto:sprevidi@cisco.com]=20 > Sent: Monday, September 19, 2016 4:17 PM > To: Alexander Vainshtein ; Jeff Tan= tsura ; Chris Bowers > Cc: spring@ietf.org > Subject: Re: [spring] meaning of "Strict Shortest Path" algorithm in = draft-ietf-spring-segment-routing-09 >=20 > Chris, Jeff, Alex, >=20 > strict-SPF behavior has been intended as the forwarding of the packet= according to spf, without any form of policy.=20 >=20 > It is true that ecmp is a matter of local implementation so we could = extend the behavior description to: >=20 > forwarding of the packet according to spf,=20 > without any form of policy and according=20 > to ecmp capability of the node. >=20 > Now, if you intentionally (through configuration) reduce the number o= f ecmp members, isn=E2=80=99t this fit the definition of a policy ? >=20 > The strict-spf behavior has been defined for exactly that purpose: al= low an instruction to override any policy decision. >=20 > Note well, I=E2=80=99m not opposed to relax the constraint and allow ecmp d= ifferences in the =E2=80=9Cstrict-spf=E2=80=9D behavior.

I'm not aware of any problemwith the current state of the document. And there already is an implementation report. The document should be sent to the IESG. The only reason not to do so might be to abandon SPRING usecase documents at all. But since we have bee asked to produce usecase documents and went along that track so far, we should IMHO proceed by promoting this document as well.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 26 Sep 2016 17:17:26 -0000 Hello Bruno, thanks for the detailed reply and apology for my late response. First, let me re-phrase what I propose. Realized that I never explained=20 exactly what I had in mind and using the "ignore" keyword was just a bad id= ea=20 too. Will avoid "ignore" as this keyword has been used in different ways=20 already. So what I propose is: if a prefix has conflicting mapping information -=20 prefix or SID conflict - then keep this prefix unlabeled. [1] I don't see that draft-ietf-spring-conflict-resolution is exactly covering= =20 this idea. Then: > But I'm not sure that you are really calling for the network operator to= =20 > have this flexibility. I actually do expect requests from network operators to implement their=20 specific view on how to operate the network into the conflict algorithm. Th= e=20 protocol design should allow for it. But there are also network operators who prefer to keep the network=20 relatively "dumb" and implement their operational logic into their OSS=20 systems. I don't see why vendors would want to impose the more complex logi= c=20 on customers not asking or not wanting it. Which is why I argue against the= =20 idea to make the preference algorithm "the" standard. (yes, "simple" or "dumb" allows for interpretation. I'm sure you get the=20 point though) Saying all this, of course we should support the request from Orange and=20 others for the preference algorithm. We do have the "algorithm" field, e.g.= =20 draft-ietf-isis-segment-routing-extensions, that could carry the=20 SPF+conflict+... algorithm required. There was also a misunderstanding about my "solving a problem that should b= e=20 rare" statement. I said it with a qualifier "with the quoted rule above" an= d=20 the rule was "Local configuration conflicts can be prevented before they are advertis= ed" If implementations check for a conflict between what they want to advertise= =20 and what is already advertised by others in the network then we filter out= =20 conflicts from config change that is happening after a time window of e.g.= =20 several seconds since the last SR config change in the network. Not saying= =20 this is a fool-proof algorithm but it puts a perspective on the problem. > Basically, what I propose is to keep it safe, and not introduce new risks sorry but I disagree. I cannot name customers but there are network operato= rs=20 who consider code complexity that they don't need a risk. To summarize: I see your point for the preference algorithm but I disagree= =20 that this should be "the" standard behaviour of Segment Routing=20 implementations. Rather we should allow for different algorithm. To have=20 basic interoperability I propose the algorithm [1] above as a starting poin= t.=20 Other algorithm can be defined within IETF if network operators are=20 interested in - we obviously have one algorithm with interest already :-) Best regards, Marc On Tue, 30 Aug 2016 17:08:24 +0000, bruno.decraene@orange.com wrote: > Hello Marc, >=20 > Speaking as an individual contributor, and network operator. >=20 > Please see inline. >=20 >> From: Marc Binderberger [mailto:marc@sniff.de] > Sent: Tuesday, August 0= 9,=20 >> 2016 9:56 AM >>=20 >> Hello Bruno and spring list experts, >>=20 >> jumping late into the discussion (sorry). >=20 > Thanks for the feedback. > =20 >>=20 >> I would see any kind of preference list to handle a conflict to be an >> somewhat arbitrary decision. >=20 > Agreed. > St=E9phane has proposed the addition of a "preference" field attached to= =20 > mapping server (advertisements) to allow a network operator to control th= is=20 > preference decision, depending on SP rules or current network status (e.g= .=20 > migrations) > To increase this capacity for customization, I guess that an option would= =20 > be to extend this preference to other SID advertisements. > But I'm not sure that you are really calling for the network operator to= =20 > have this flexibility.

I have some minor comments= and possible syntax corrections for the authors. Minor: ------ In my opinion, the document should further explain if it's proposing a new = system or outlining what must be there in existing systems. Do we want to i= mplement such a data plane validation or enhance/reuse BFD for that purpose= ? Note in Page 5: Why will the PMS host not be part of MPLS domain? Isn't it = given because a) solution applies to IGP and host will be part of IGP, and = b) The top label is for path from PMS to LER I so there is an MPLS path the= re Paragraph 1, Page 8: "The PMS further could be enabled to send MPLS OAM pac= kets with the label stack and address information identical to those of the= monitoring packets to any node of the MPLS domain". Can you please clarify= this? I don't understand the use case. Section 6 mentions the applicability of this solution for LDP but leaves ou= t RSVP-TE tunnels. Won't it also be beneficial in monitoring active RSVP-TE= tunnels as well? Syntax: ------- Paragraph 2 on Page 3 should read "This document describes a system of usin= g MPLS data plane pat monitoring capabilities" instead of "This document de= scribes illustrates a system of using MPLS data plane pat monitoring capabi= lities" Paragraph 2, Page 3: Change "The use case introduced here" to "The use case= s introduced here" Paragraph 5, Page 3: Shouldn't it read "pre-Segment Routing (SR) based tech= nology" instead of "pre-Segment based Routing (SR) technology"? Paragraph 5, Page 3: Change "domains complete MPLS topology" to "domain's c= omplete MPLS topology" Paragraph 5, Page 3: Change "domains forwarding plane" to "domain's forward= ing plane" Paragraph 2, Page 4: Change "recongise an execute" to "recognise and execut= e" Paragraph 4, Page 4: Change "The MPLS path monitoring system may be a any s= erver" to "The MPLS path monitoring system may be at any server" Paragraph 2, Page 5: Change "monitor the path of it to LER j and then recei= ve the packet back" to "monitors its path to LER j and then receives the pa= cket back" Bullet 3, Page 7": Remove "to" from "The path LER j to PMS to must be avail= able" Regards, Faisal Iqbal -----Original Message----- From: spring [mailto:spring-bounces@ietf.org] On Behalf Of Martin Horneffer Sent: Monday, September 26, 2016 8:02 AM To: spring@ietf.org Subject: Re: [spring] WGLC for draft-ietf-spring-oam-usecase Hello everyone, speaking as co-worker of one of the editors: From my own viewpoint I think = this document makes a lot of sense and is in a good state.

Regards, Ruediger -----Urspr=FCngliche Nachricht----- Von: spring [mailto:spring-bounces@ietf.org] Im Auftrag von Faisal Iqbal (f= aiqbal) Gesendet: Dienstag, 27. September 2016 06:13 An: bruno.decraene@orange.com; spring@ietf.org Cc: spring-chairs@ietf.org Betreff: Re: [spring] WGLC for draft-ietf-spring-oam-usecase Hi, This is a useful and very well-written document. I have some minor comments= and possible syntax corrections for the authors. Minor: ------ In my opinion, the document should further explain if it's proposing a new = system or outlining what must be there in existing systems. Do we want to i= mplement such a data plane validation or enhance/reuse BFD for that purpose= ? [RG] The outlined system works with MPLS as is today. BFD could be implemen= ted as part of a PMS to monitor a path. I'll add text to state that (in tha= t case, scalability has to be regarded and determination of the failing pat= h).=20 Note in Page 5: Why will the PMS host not be part of MPLS domain? Isn't it = given because a) solution applies to IGP and host will be part of IGP, and = b) The top label is for path from PMS to LER I so there is an MPLS path the= re. [RG] It is just one option that the PMS is not part of the MPLS domain (the= latter is the best option for a realization). It should be part of the IGP= domain. But a design with a PMS neither being part of the MPLS domain, nor= being part of the IGP domain is possible. I'll clarify that. Paragraph 1, Page 8: "The PMS further could be enabled to send MPLS OAM pac= kets with the label stack and address information identical to those of the= monitoring packets to any node of the MPLS domain". Can you please clarify= this? I don't understand the use case. [RG] I'll add some text. MPLS OAM allows to detect routing of packets along= ECMP paths. So there are choices, if a path between LERi - LSRx/LSRy - LER= j is to be monitored: either detect a desired path crossing, say, LSRx to = be used=20 - by MPLS OAM and only send the monitoring packet with Label LERy and a sui= table IP dest address from LERj or - use a Label stack (LSRx) and LSRj (PHP will have removed the former). Section 6 mentions the applicability of this solution for LDP but leaves ou= t RSVP-TE tunnels. Won't it also be beneficial in monitoring active RSVP-TE= tunnels as well? [RG] Let's add a "possibly also RSVP-TE" here, I don't know for sure. Deuts= che Telekom developed such a system for an LDP signaled MPLS domain. I can'= t discuss how to build it for RSVP-TE signaled tunnels (and don't want to b= e obliged to do that). Syntax: [RG] will be picked up for the next version.... ------- Paragraph 2 on Page 3 should read "This document describes a system of usin= g MPLS data plane pat monitoring capabilities" instead of "This document de= scribes illustrates a system of using MPLS data plane pat monitoring capabi= lities" Paragraph 2, Page 3: Change "The use case introduced here" to "The use case= s introduced here" Paragraph 5, Page 3: Shouldn't it read "pre-Segment Routing (SR) based tech= nology" instead of "pre-Segment based Routing (SR) technology"? Paragraph 5, Page 3: Change "domains complete MPLS topology" to "domain's c= omplete MPLS topology" Paragraph 5, Page 3: Change "domains forwarding plane" to "domain's forward= ing plane" Paragraph 2, Page 4: Change "recongise an execute" to "recognise and execut= e" Paragraph 4, Page 4: Change "The MPLS path monitoring system may be a any s= erver" to "The MPLS path monitoring system may be at any server" Paragraph 2, Page 5: Change "monitor the path of it to LER j and then recei= ve the packet back" to "monitors its path to LER j and then receives the pa= cket back" Bullet 3, Page 7": Remove "to" from "The path LER j to PMS to must be avail= able" Regards, Faisal Iqbal -----Original Message----- From: spring [mailto:spring-bounces@ietf.org] On Behalf Of Martin Horneffer Sent: Monday, September 26, 2016 8:02 AM To: spring@ietf.org Subject: Re: [spring] WGLC for draft-ietf-spring-oam-usecase Hello everyone, speaking as co-worker of one of the editors: From my own viewpoint I think = this document makes a lot of sense and is in a good state.
