To facilitate tracking of these spring-related drafts, we would really appr= eciate it if "-spring-" is included somewhere in the name of the document..= obviously after the adopting WG name. For drafts not targeted at spring that have already been published without = "-spring-" in the title, please send a note to the WG to let us know which = ones they are. Thanks! Alvaro.

All,

we just submitted, in 6MAN, draft-previdi-6man-segment-routing-header-00 which consists of the ipv6 dataplane instantiation of segment routing
(through the definition of a new routing header type).

We also submitted, in SPRING, draft-martin-spring-segment-routing-ipv6-use-= cases-00
which illustrates the use cases for the Segment Routing Header.

Segment Routing is defined in draft-filsfils-rtgwg-segment-routing-01
and draft-filsfils-rtgwg-segment-routing-use-cases-02 currently discussed in SPRING WG (a rename of the drafts will happen soon so to reflect the
WGs where they are worked out).

Thanks.

Hey Stefano,

 <= /p>

If I extrapolate the link= overhead from the SP data that I got and presented at the last IETF the 4 = x larger per segment overhead for this header translates into a 24% increase in link utilization for the PW mobile backhaul link da= ta that I have and a 7% approx overhead for the remainder of the SP links (= assuming only 3 hops). This is compared to a 7% and 2% overhead respectivel= y for MPLS (also 3 hops).

 <= /p>

http://www.ietf.org/pro= ceedings/88/slides/slides-88-spring-4.pdf  (last chart).

 <= /p>

I am not sure what kinds = of overheads are acceptable but I suspect that 5% is ‘sort of accepta= ble’ but getting into the high teens is ‘less so’.

 <= /p>

We may need to consider s= ome kind of compression. For example it would be possible to store shorter = or even variable sized segment id’s. If for example the header included a segment id size field the segment list could even be sma= ller than the MPLS segment list in some circumstances. Of course then you&#= 8217;d need to indirect to get the IPV6 addresses.

Hi Stefano= and Peter,

I have the= same concern as Peter here, 128-bit segment SID seems too large. IMHO, we = could use a shorter SID (32-bit SID) , just as originally proposed in the SR architecture draft, and then using a mapping mechanisms= to translate the 32-bit SID to an IPv6 address at each SR-capable router. =

This is compared to a 7% and 2% overhead = respectively for MPLS (also 3 hops).

 = ;

http://w= ww.ietf.org/proceedings/88/slides/slides-88-spring-4.pdf  (last chart).

 = ;

I am not s= ure what kinds of overheads are acceptable but I suspect that 5% is ‘= sort of acceptable’ but getting into the high teens is ‘less so= ’.

 = ;

We may nee= d to consider some kind of compression. For example it would be possible to= store shorter or even variable sized segment id’s. If for example the header included a segment id size field the segment list could= even be smaller than the MPLS segment list in some circumstances. Of cours= e then you’d need to indirect to get the IPV6 addresses.

Of course t= hen you=92d need to indirect to get the IPV6 addresses. variable size segment identifiers is an appealing solution but it comes with other challenges. However, I agree with you, there are efficient compression techniques=20 we could use, especially if the scope of a SR-IPv6 deployment is=20 within an operator infrastructure (i.e.: single domain). One being the=20 use of a common prefix within the domain and allocated to SR and you'd specify only the host bits (as SID). Keeping in mind that using v6 address requires no specific signaling=20 for SR (prefixes are advertised anyway).

Of course the= n you'd need to indirect to get the IPV6 addresses. variable size segment identifiers is an appealing solution but it comes wit= h other challenges.

Since there are a small finite number of values of M that we care about the= encoding can be very simple. For example I imagine {8,16,32,48,64,..128} w= ould likely be a fairly complete set so we only need ~four bits to encode '= M' in the header.=20 Something along those lines would give very compact encodings for small net= works and be flexible to 'just the right size' for bigger networks and is o= f course fairly simple to implement quickly in hardware.

I=B9m assuming when the full SID list needs to be put in the header, it is possible to aggregate the data into a larger MTU packet within the core. So you may have higher overhead on small data packets (that aren=B9t a significant amount of traffic), but you could be much more efficient with large data packets which make up the majority of traffic (i.e..video).

However, this is not WG last call, but WG adopti= on. IMO, adopting draft-previdi-isis-segment-routing-extensions is the best= way to have the IETF ISIS WG helps refining this document. I really don't think it's too early. IIRC, the doc is 1 year old now (since= Orlando), and multiple implementations are underway. IMHO the more we woul= d wait, the less chance for the IETF participants (including you) to be abl= e to contribute and influence the document, because once implementations ar= e done, people are more reluctant to make non compatible /significant chang= es. Regarding your doubt about scalability, - if they concern this document (ISIS extension), it would be useful if you= could provide a more specific feedback about this. - if they do not concern this ISIS document, but rather a/some Segment Rout= ing uses cases, it would probably be better to raise them in the spring wor= king under a thread topic specific to the related draft/use case. In partic= ular, if you believe that the FRR use case or solution raise "scalability i= ssue" or "doubt about future deployment" I would be interested in the topic.

The server can not preserves MPLS label. The MPLS = labels get lost when the packets pass through the service node. Can you ple= ase name a commercial service node or application can preserves MPLS labels= ? And do you think SR-MPLS is pure networking job and it is extra requireme= nt for an application to preserves MPLS labels? Normally PE or P strips MPL= S labels before the application receive them.=20 DPI can decide next services for this packet (like pass through or bypass f= irewall) but it is burden to decide the exact route (label stack). The whol= e route for this packet depends on some other requirements like latency, ba= ndwidth, jitter, reliability, traffic load, policy, cost and so on, in addi= tion to the next services. If DPI decision is label stack, that means the e= xact route, isn't it? Is the requirement for DPI too high? How does to use SR to realize service chaining compares with to use SDN to = realize service chaining? Looks SDN is more flexible in this case and does = not put extra requirements on service nodes. Do you think SR service chaini= ng is interim solution until SDN becomes a general practice?

In "5. Service chaining" example, is there risk that the segmen= t header gets lost along the service chain when passing through a Service N= ode like D?

Hello Zhang,

You are perhaps right that MPLS header is lost at your service node. Howeve= r I do think that IPv6 header would not be lost therefor SR could still be = used just fine to either pass through such service node or get redirected v= ia standard redirection mechanism .. usually new encapsulation or forwardin= g via different directly connected interface or tee like behavior.=A0

It really does not matter if you are = stuck to using MPLS for some reason if the label comes from the far away ed= ge or magic SDN controller imposing it on the return traffic from your serv= ice node. As a matter of fact you can do the same operation on the edge con= necting your vanilla service node. But I would rather use IPv6 encapsulatio= n ;)

Best,

Hi Stefano

Thanks for the reply.

I have only one service node with DPI and Content Filtering function in my = lab and I gave it a try. The server can not preserves MPLS label. The MPLS = labels get lost when the packets pass through the service node. Can you ple= ase name a commercial service node or application can preserves MPLS labels= ? And do you think SR-MPLS is pure networking job and it is extra requireme= nt for an application to preserves MPLS labels? Normally PE or P strips MPL= S labels before the application receive them.

DPI can decide next services for this packet (like pass through or bypass f= irewall) but it is burden to decide the exact route (label stack). The whol= e route for this packet depends on some other requirements like latency, ba= ndwidth, jitter, reliability, traffic load, policy, cost and so on, in addi= tion to the next services. If DPI decision is label stack, that means the e= xact route, isn't it? Is the requirement for DPI too high?

How does to use SR to realize service chaining compares with to use SDN to = realize service chaining? Looks SDN is more flexible in this case and does = not put extra requirements on service nodes. Do you think SR service chaini= ng is interim solution until SDN becomes a general practice?

Thanks
Yuantao

that specific example assumes that the application preserves/ignore either = the label stack (SR-MPLS) or the IPv6 Segment Routing Header (SR-IPv6).

yes.

DPI would maintain state (configuration/policy?) based on what services are= to be applied to which flow. This is orthogonal to the method you use (or = could use) in order to implement service chaining.

E.g.: in segment routing, the outcome of the DPI decision would be a label = stack (SR-MPLS) or a IPv6 segment routing header (SR-IPV6).

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 12 Mar 2014 18:56:15 -0000 A clear problem statement is needed before protocol extensions can be defined. For example: 1. If node protection of SR paths is desirable, then it may be necessary to advertise SRLG. 2. If lack of Entropy Label capability (ELC) on a subset of interfaces is common, then ELC advertised per LSP is needed. 3. etc. Not yet knowing the set of requirements, it is not possible to define the protocol solution. Therefore I don't think this should become a WG until work in the spring WG progresses further. It is still fine to discuss the quality of this document as an individual submission, but for now it defines a TLV container for which spring WG has not decided on the content. There are major differences between the topologies of DC (fat tree) and the topologies of SP (mesh, commonly interconnected meshes, each mesh generally sparsely physically connected, but each mesh fully connected by MPLS). General type of topology has a major impact on scalability. Spring WG problem statement should also be clear about which of these problem spaces spring resides in. If both, solutions must be stable in both. Once there is a problem statement and framework, it makes more sense to discuss scalability.

Please refer to following my reply. 1. Regarding concern about the scalability issues and the future deployment, I have explained in the link http://www.ietf.org/mail-archive/web/spring/current/msg00559.html. 2. Regarding the segment routing for FRR, I agree that it is truly a useful usecases and I also read the draft "draft-francois-segment-routing-ti-lfa-00" carefully. 1) My concern is still from "4.4. Connecting distant P and Q nodes along post-convergence paths". Since this will cause deeper label stacks, I wonder if your can provide the research result on how often the case will happen in a normal network just like the MRT for which Alia, Chris Bowers, etc., provides detailed algorithm analysis based on different typical topologies. 2) In addition, I still concern about two scenarios about the segment routing for FRR: -- For the scenarios to be compatible with the existing MPLS LDP network, even if the segment routing path is used, LDP remote peer has to be set up which will have much effect on the practical deployment. -- For the scenarios only using segment routing path, since the primary path uses the segment routing path with a list of segments, even if there are not many segments in the backup path, the segments in the primary path plus the segments in the backup path maybe cause deeper label stacks. Regarding my concern about scenarios in 1) and 2), I wish the detailed analysis and reasonable solutions from you would help convince us. On the other hand we will also do the similar research on the topic. 3. Regarding the ISIS extensions, I need some clarification to help understand the protocol extensions design: 1) From my point of view, for better compatibility, I hope all the label allocation can use "SID/Label Binding TLV" instead of affect many exiting ISIS TLVs. Current ISIS extensions for segment routing will have effect on many existing TLVs besides the new TLV "SID/Label Binding TLV", is it just for convenience? 2) Regarding the label allocation, in my presentation in IETF89 ISIS WG for draft-li-isis-mpls-multi-topology-00, I explain my opinions: -- Decouple segment and label. In Sec 2.1 "SID/Label Sub-TLV", the segment and label are mixed together. And it depends length to differentiate. I do not think it is a good way. In addition, for the scalability, it is better that the label stack should be defined here like label BGP in RFC 3107 instead of only one label for the TLV. If so, the length is not a good way to differentiate. -- For the global label allocation method, I explained my concern in http://www.ietf.org/mail-archive/web/spring/current/msg00559.html about the upgrading issues for the reseved SRGB. If the method cannot convince us enough or maybe centrol control is a better way to allocate global label, it is early to define the prototol extensions. I think segment routing will have much effect on the existing network and the future network. Until now, there are still existing and mature solutions for the usecase proposed for segment routing which may be not perfect as claimed comparing with segment routing. On the other hand, more research work should be done for segment routing to prove it is truly a good alternative. My concern is listed as above, both for segment routing's use cases and ISIS extensions for SR. I hope the discussion would help determine a better solutions and protocol extensions.

However, this is not WG last call, but WG adoption. IMO, adopting draft-previdi-isis-segment-routing-extensions is the best way to have the IETF ISIS WG helps refining this document. I really don't think it's too early. IIRC, the doc is 1 year old now (since Orlando), and multiple implementations are underway. IMHO the more we would wait, the less chance for the IETF participants (including you) to be able to contribute and influence the document, because once implementations are done, people are more reluctant to make non compatible /significant changes. Regarding your doubt about scalability, - if they concern this document (ISIS extension), it would be useful if you could provide a more specific feedback about this. - if they do not concern this ISIS document, but rather a/some Segment Routing uses cases, it would probably be better to raise them in the spring working under a thread topic specific to the related draft/use case. In particular, if you believe that the FRR use case or solution raise "scalability issue" or "doubt about future deployment" I would be interested in the topic.

Hi!

We're going to start a WG Adoption Call for these use case drafts:


To accelerate the process, the call for adoption will go out for each = draft individually, but the expectation is that they will be merged into on= e WG document.

Authors:  There is already some overlap in the author lists, so i= t will be left up to you do elect an editor (or set of editors) for the com= bined draft.  All other authors can of course be listed as Contributor= s.

In parallel with the call for adoption, an IPR claims question will al= so go out.  We require that all authors/contributors re= ply before we can progress the document.

If anyone wants to contribute more significant use cases, please publi= sh them as soon as possible.

Please use this thread to address any process questions.

Thanks!

Alvaro.

Hi!

This message officially starts the call for adoption for draft-previdi-spring-problem-statement.

Please indicate your position about adopting this use cases draft by end-of-day on March 27, 2014.

Some additional background:  We had issued a call for adoption for draft-filsfils-rtgwg-segment-routing-use-cases-02 back in November.  From both the discussion at the meeting in Vancouver and on the list, there was consensus to adopt.  The authors published draft-previdi-spring-problem-statement-00 as a revision to the original draft without the solution being present in the use case description.


Thanks!

Hi!

We're going to start a WG Adoption Call for these use case drafts:


To accelerate the process, the call for adoption will go out for each draft individually, but the expectation is that they will be merged into one WG document.

Authors:  There is already some overlap in the author lists, so it will be left up to you do elect an editor (or set of editors) for the combined draft.  All other authors can of course be listed as Contributors.

In parallel with the call for adoption, an IPR claims question will also go out.  We require that all authors/contributors reply before we can progress the document.

If anyone wants to contribute more significant use cases, please publish them as soon as possible.

Please use this thread to address any process questions.

Thanks!

Alvaro.

Adjacency-SID The Adjacency-SID identifies a given interface. In the SR architecture a node may advertise one or more Adj-SIDs allocated to a given interface so to force the forwarding of the packet (when received with that particular Adj-SID) into the interface, regardless the routing entry for the packet destination. The same is defined for SR-IPv6: a node may advertise a given IPv6 prefix which is associated to the SR semantic of "send out the packet to the interface this prefix is allocated to". Here also, the SID is in fact the IPv6 prefix. --- my interpretation of the *changed* 'Adjacency-SID' semantics above is = that it is not possible any longer to do 'strict explicit routing' like we = used to do in the MPLS incarnation of SR. i.e. in SR-MPLS an 'adjacency-SID' represents a forwarding action that will = drop traffic at a specific neighbor using a specific link - no matter what. in SR-IPv6 an 'adjacency-SID' represents a forwarding action that will = drop traffic at a specific neighbor using *the most specific IP6 hop-by-hop* = forwarding path. (to spoil the party - consider injecting a more specific route for the = remote-end of the link) may i ask the reasoning for giving up strict explicit routing in the = SR-IPv6 dataplane ? my understanding of one of the values that SR does bring is 'strict = explicit routing' and as such i am worried about consistency between the two data planes; playing a bit devils advocate: one could argue that you can build the = same (loose source routing plus indicator where a packet does came from) = using nested IP tunnels ... /hannes On Mar 6, 2014, at 11:21 AM, Stefano Previdi (sprevidi) wrote: > All, >=20 > here below you'll find the pointers to: > draft-martin-spring-segment-routing-ipv6-use-cases-00 > draft-previdi-6man-segment-routing-header-00 >=20 > that have been submitted today. >=20 > Any comment, contribution, suggestion, flames,... are welcome. >=20 > s. >=20 >=20 > Begin forwarded message: >> A new version of I-D, = draft-martin-spring-segment-routing-ipv6-use-cases-00.txt >> has been successfully submitted by Roberta Maglione and posted to the >> IETF repository. >>=20 >> Name: = draft-martin-spring-segment-routing-ipv6-use-cases >> Revision: 00 >> Title: IPv6 Segment Routing Use Cases >> Document date: 2014-03-06 >> Group: Individual Submission >> Pages: 12 >> URL: = http://www.ietf.org/internet-drafts/draft-martin-spring-segment-routing-ip= v6-use-cases-00.txt >> Status: = https://datatracker.ietf.org/doc/draft-martin-spring-segment-routing-ipv6-= use-cases/ >> Htmlized: = http://tools.ietf.org/html/draft-martin-spring-segment-routing-ipv6-use-ca= ses-00 >>=20 >>=20 >> Abstract: >> Segment Routing (SR) leverages the source routing paradigm.

Hi!

This message officially starts the call for adoption for draft-previdi-spring-problem-statement.

Please indicate your position about adopting this use cases draft by end-of-day on March 27, 2014.

Some additional background:  We had issued a call for adoption for draft-filsfils-rtgwg-segment-routing-use-cases-02 back in November.  From both the discussion at the meeting in Vancouver and on the list, there was consensus to adopt.  The authors published draft-previdi-spring-problem-statement-00 as a revision to the original draft without the solution being present in the use case description.


Thanks!

Alvaro.

I received a couple of comments related to what I wrote below.. >Please keep in mind that this specific draft is targeted at 6man; it is >great that spring is being cc'd, but the discussion should really happen >in 6man. ..so I want to clarify. It is great that the discussion about this draft (and any other for that matter) is occurring on the list! However, this draft is targeted at 6man -- that WG will have to make any decisions around it. The more information 6man has about the draft itself, the requirements, any concerns, etc. the better the decision they will be able to make, so please make sure that they are also part of the discussion. The point that I tried to make above was not about moving the discussion elsewhere and not including spring. Quite the opposite: please make sure that spring is cc'd when the related drafts are discussed in other WG lists. That will keep everyone in sync and will avoid the need to potentially have discussions twice. Just a quick reminder (this is from a message I sent to the list on March/6): =3D=3D=3D=3D=3D As was discussed in yesterday's meeting, the RTG ADs have provided guidance about spring-related drafts in other WGs. In short, other WGs may adopt the drafts as long as (1) they are discussed in spring as well, (2) WGLC takes place in both the adopting WG and spring, and (3) the WGLC takes place after spring has adopted an architecture and corresponding use case. =3D=3D=3D=3D=3D I realize that 6man is not in the RTG area, but the general principle of discussing the drafts in both the adopting WG and spring still applies.

Alvaro,

 

Merging draft-prevedi-spring-problem-statement with = draft-martin-spring-segment-routing –ipv6-uses-cases might result in = a document that is at cross purposes with itself. Draft-prevedi is a proble= m statement document. Its goal is to identify problems that will be solved by SPRING. Draft-martin is a solution documen= t. It assumes one particular solution, ignoring the possibility of other so= lutions that may or may not be related to IPv6.

RFC 791 defines their sem= antics as follows: [Strict] "This option is a strict source route because the gateway or host IP must send the datagram directly to the next address in the source route through only the directly connected network indicated in the next address to reach the next gateway or host" specified in the route. [Loose] "This option is a loose source route because the gateway or host IP is allowed to use any route of any number of other intermediate gateways to reach the next address in the route." According to RFC 2460, "The Routing header is used by an IPv6 source to lis= t one or more intermediate nodes to be "visited" on the way to a packet's d= estination. This function is very similar to IPv4's Loose Source and Recor= d Route option." IPv6 never had anything like a strict source routing option. If you want a = strict source routing semantic, you should consider the following: - Updating RFC 2460. The above quoted text will need to be changed - Adding a flag to the SRH that indicates whether strict or loose source ro= uting is intended - Specifying which address types are allowed in the segment list when loose= source routing is specified (global unicast? ULA? LLA?) - Specifying which address types are allowed in the segment list when stric= t source routing is specified (global unicast? ULA? LLA?) I don't think that the interface identifier bits of the IPv6 address will h= elp much. Recall that the nodes in a routing header represent "intermediate= nodes to be "visited" on the way to a packet's destination", not outbound = interfaces.=20 Ron -----Original Message----- From: spring [mailto:spring-bounces@ietf.org] On Behalf Of Stefano Previdi = (sprevidi) Sent: Monday, March 17, 2014 4:58 PM To: Hannes Gredler Cc: spring@ietf.org; Clarence Filsfils (cfilsfil) Subject: Re: [spring] SR-IPv6 drafts / strict explicit routing concerns Hi Hannes, On Mar 17, 2014, at 4:49 PM, Hannes Gredler wrote: > hi stefano, >=20 >=20 > thanks for submitting the document(s). > had a look at 'draft-previdi-6man-segment-routing-header' and i have=20 > concerns about section 4.2.2 - specifically: >=20 > --- > 4.2.2.

you're right and the text needs to be changed.

The adj-sid/ipv6 address must be used in order to forward the packet onto t= he link, no matter what routing says.

After all, ipv6 has defined bits in the address as "interface identifi= er"
so, also there, we have a natural v6 property for the adj-sid.

Hi Alvaro,

I think that merging draf= t-francois-spring-resiliency-use-case with the rest of listed documents may= not be the best  course. Perhaps, instead of merging this document, which I support to be adopted by SPRING WG, be expanded to addre= ss applicability of various mechanisms that enable survivability within Seg= ment Routing domain.

Hi!

 

We're going to start a WG A= doption Call for these use case drafts:

 

 

To accelerate the process, = the call for adoption will go out for each draft individually, but the expe= ctation is that they will be merged into one WG document.=

 

Authors:  There is alr= eady some overlap in the author lists, so it will be left up to you do elec= t an editor (or set of editors) for the combined draft.  All other authors can of course be listed as Contributors.

 

In parallel with the call f= or adoption, an IPR claims question will also go out.  We require that all authors/contributors reply before we can progress the docum= ent.

 

If anyone wants to contribu= te more significant use cases, please publish them as soon as possible.

 

Please use this thread to a= ddress any process questions.

 

Thanks!

you're right and the text needs to be changed.

The adj-sid/ipv6 address must be used in order to forward the packet onto t= he link, no matter what routing says.

After all, ipv6 has defined bits in the address as "interface identifi= er"
so, also there, we have a natural v6 property for the adj-sid.

Very close to what Robert suggested.=20 2. advertise a flag in the existing IGP advertisement of the prefix giving= =20 the same semantic as above. Now, this will also incur an update of the initial paragraph of section 4=20 (claiming no additional advertisement is needed). Not a big deal imho. s.

Please observe that nothing prevents you = to insert your peer's interface address (for example advertised as pass= ive into IGP) into routing's header and remove it just before it is advertised outside of the domain.

That way effectively and in line with RFC= 2460 you will only use "intermediate nodes" yet achieve well the= requirement of lookup less forwarding via an exit ASBR.

Stefano,

IPv4 has loose and strict source routing options. RFC 791 defines their sem= antics as follows:

 [Strict] "This option is a strict source route because the gatew= ay or host
        IP must send the datagram directly to the next = address in the
        source route through only the directly connecte= d network
        indicated in the next address to reach the next= gateway or host"

 [Loose] "This option is a loose source route because the gateway= or host
        IP is allowed to use any route of any number of= other
        intermediate gateways to reach the next address= in the route."

According to RFC 2460, "The Routing header is used by an IPv6 source t= o list one or more intermediate nodes to be "visited" on the way = to a packet's destination.  This function is very similar to IPv4&= #39;s Loose Source and Record Route option."

IPv6 never had anything like a strict source routing option. If you want a = strict source routing semantic, you should consider the following:

- Updating RFC 2460. The above quoted text will need to be changed
- Adding a flag to the SRH that indicates whether strict or loose source ro= uting is intended
- Specifying which address types are allowed in the segment list when loose= source routing is specified (global unicast? ULA? LLA?)
- Specifying which address types are allowed in the segment list when stric= t source routing is specified (global unicast? ULA? LLA?)

I don't think that the interface identifier bits of the IPv6 address wi= ll help much. Recall that the nodes in a routing header represent "int= ermediate nodes to be "visited" on the way to a packet's dest= ination", not outbound interfaces.

you're right and the text needs to be changed.

The adj-sid/ipv6 address must be used in order to forward the packet onto t= he link, no matter what routing says.

After all, ipv6 has defined bits in the address as "interface identifi= er"
so, also there, we have a natural v6 property for the adj-sid.

AFAIKS, Hannes' original = comment concerned the forwarding plane. It can be restated as follows: Assume that an SR-aware node receives a packet. The packet's DA is local to= the node, so the nodes examines the IPv6 extension header chain. The IPv6 = extension header chain contains an SRH and the next segment on the SRH is r= eachable. However, the next segment is not directly connected. It is reacha= ble through an intermediate node. If strict source routing semantics are to be enforced, the node should disc= ard the packet. If loose source routing semantics are to be enforced, the n= ode should forward the packet through the intermediate node. By looking at = the packet, how does the IPv6 forwarder know whether to enforce strict or l= oose source routing semantics? Here, I assume that SPRING/IPv6 supports both strict and loose source routi= ng semantics, as does SPRING/MPLS.=20 Ron -----Original Message----- From: Stefano Previdi (sprevidi) [mailto:sprevidi@cisco.com]=20 Sent: Wednesday, March 19, 2014 9:58 AM To: Ronald Bonica Cc: Hannes Gredler; spring@ietf.org; Clarence Filsfils (cfilsfil) Subject: Re: [spring] SR-IPv6 drafts / strict explicit routing concerns Ron, thanks for the info, I have to admit I'm not very familiar with rfc791 ;-) >From a practical perspective I see the following options: 1. advertise, in the IGP, a prefix with the semantic "forward to the link=20 this prefix is assigned to".

IPv4 has loose and strict source routing options. RFC 791 defines their sem= antics as follows:

 [Strict] "This option is a strict source route because the gatew= ay or host
        IP must send the datagram directly to the next = address in the
        source route through only the directly connecte= d network
        indicated in the next address to reach the next= gateway or host"
        specified in the route.

 [Loose] "This option is a loose source route because the gateway= or host
        IP is allowed to use any route of any number of= other
        intermediate gateways to reach the next address= in the route."

According to RFC 2460, "The Routing header is used by an IPv6 source t= o list one or more intermediate nodes to be "visited" on the way = to a packet's destination.  This function is very similar to IPv4's Lo= ose Source and Record Route option."

IPv6 never had anything like a strict source routing option. If you want a = strict source routing semantic, you should consider the following:

- Updating RFC 2460. The above quoted text will need to be changed
- Adding a flag to the SRH that indicates whether strict or loose source ro= uting is intended
- Specifying which address types are allowed in the segment list when loose= source routing is specified (global unicast? ULA? LLA?)
- Specifying which address types are allowed in the segment list when stric= t source routing is specified (global unicast? ULA? LLA?)

I don't think that the interface identifier bits of the IPv6 address will h= elp much. Recall that the nodes in a routing header represent "interme= diate nodes to be "visited" on the way to a packet's destination&= quot;, not outbound interfaces.

you're right and the text needs to be changed.

The adj-sid/ipv6 address must be used in order to forward the packet onto t= he link, no matter what routing says.

After all, ipv6 has defined bits in the address as "interface identifi= er"
so, also there, we have a natural v6 property for the adj-sid.

The behavior is determined by the SID. Each node advertises its SIDs. Each SID is associated with a semantic (strict or loose). In SR-MPLS you=20 advertise labels as: . Prefix/Node-SIDs: these have the "loose" semantic. . Adjacency-SIDs: these have the "strict" semantic. In SR-IPv6 we do the same: . IPv6 prefix: "loose" semantic. . IPv6 prefix with a (new) flag: "strict" semantic. Example:=20 . NodeA and NodeB are connected through interface X which has prefix P . NodeA and NodeB advertise prefix P with a flag (in SR subTLV) stating the "strict" semantic is used if such prefix is found in the segment=20 list as active segment. . Any node in the network can now send a packet with following segment=20 list: . NodeA-loopback-address . prefix-P The packet will first arrive (loose) in NodeA which will examine the=20 next segment and find prefix-P. The semantic of prefix-P bing "forward=20 to the interface this prefix is allocated to" NodeA will forward the=20 packet accordingly (strict).

If we are talking about i= nterface addresses (128 bits), my original question remains unanswered. How= does the IPv6 forwarding plane know whether to enforce strict or loose source routing semantics?

 

However, you do bring up = another interesting question. Do you really want to include link-local addr= esses in the segment list? You clearly can’t do this when loose source routing semantics are enforced. It might not even be a good i= dea with strict source routing. This is because a node might have two neigh= bors, attached through different interfaces, that coincidentally (or not so= coincidentally) have the same link-local address.

We may be taking past one= another. In your message below, which of the following did you mean:

 

-          You can insert the peer’s interface= address (i.e., 128 bits) into the SRH

-          You can insert the peer’s interface= identifier (i.e., less than 128 bits, as defined in Section 2.5 of RFC 429= 1) into the SRH

 

I believe that Stephano a= nd I are talking identifiers, not interface addresses. Is that also what you are talking about?

Please observe that nothing prevents you = to insert your peer's interface address (for example advertised as pass= ive into IGP) into routing's header and remove it just before it is advert= ised outside of the domain.

That way effectively and in line with RFC= 2460 you will only use "intermediate nodes" yet achieve well the= requirement of lookup less forwarding via an exit ASBR.

Stefano,

IPv4 has loose and strict source routing options. RFC 791 defines their sem= antics as follows:

 [Strict] "This option is a strict source route because the gatew= ay or host

        source route through only the directly connecte= d network
        indicated in the next address to reach the next= gateway or host"

 [Loose] "This option is a loose source route because the gateway= or host
        IP is allowed to use any route of any number of= other
        intermediate gateways to reach the next address= in the route."

According to RFC 2460, "The Routing header is used by an IPv6 source t= o list one or more intermediate nodes to be "visited" on the way = to a packet's destination.  This function is very similar to IPv4&= #39;s Loose Source and Record Route option."

IPv6 never had anything like a strict source routing option. If you want a = strict source routing semantic, you should consider the following:

- Updating RFC 2460. The above quoted text will need to be changed
- Adding a flag to the SRH that indicates whether strict or loose source ro= uting is intended
- Specifying which address types are allowed in the segment list when loose= source routing is specified (global unicast? ULA? LLA?)
- Specifying which address types are allowed in the segment list when stric= t source routing is specified (global unicast? ULA? LLA?)

I don't think that the interface identifier bits of the IPv6 address wi= ll help much. Recall that the nodes in a routing header represent "int= ermediate nodes to be "visited" on the way to a packet's dest= ination", not outbound interfaces.

you're right and the text needs to be changed.

The adj-sid/ipv6 address must be used in order to forward the packet onto t= he link, no matter what routing says.

After all, ipv6 has defined bits in the address as "interface identifi= er"

Hello,

I have been following this list on Segment routing for some time now, yet today I dare to write this message because I have a question regarding the work done on the OSPF routing extension and on IPv6 segment routing use case.

From my understanding, IPv6 has been suggested as a dataplane technology for segment routing in a draft, and some OSPF extensions have been drafted in order for routers to exchange node or segment IDs. Yet, the OSPF draft only mentions adaptations to perform to OSPFv2. So, I am wondering if an extension to OSPFv3 is planned for the next future. As the focus now is on clarifying the problem statement and use cases, this might be a bit early, but as extensions have already been suggested for OSPFv2, maybe some members on the list are already working on this.

Thanks in advance for your answers,

Antoine Fressancourt

Originally, sr extensions for v6 have been d= ocumented in
draft-psenak-ospf-segment-routing-ospfv3-extension-01.

However, draft-previdi-6man-segment-routing-header-00 describes how
sr can be used over v6 dataplane and makes no use of explicit SIDs
anymore (which means you 'could' use sr-ipv6 without any extensions= ).

Note that recently, with the help of Hannes and Ron, we found out that
we may still want to advertise some bits in case of the adj-sid for
ipv6.

However, it is inferred from the SID. The= FIB entry for the SID includes a new attribute that determines whether sou= rce routing to this SID is loose or strict. Do I have this much right? If so, are any other new attributes included in the FIB entry? For example,= is the keying material required to authenticate the MAC also included?

AFAIKS, Hannes' origina= l comment concerned the forwarding plane. It can be restated as follows: >=20 > Assume that an SR-aware node receives a packet. The packet's DA is local = to the node, so the nodes examines the IPv6 extension header chain. The IPv= 6 extension header chain contains an SRH and the next segment on the SRH is= reachable. However, the next segment is not directly connected. It is reac= hable through an intermediate node. >=20 > If strict source routing semantics are to be enforced, the node should di= scard the packet. If loose source routing semantics are to be enforced, the= node should forward the packet through the intermediate node. By looking a= t the packet, how does the IPv6 forwarder know whether to enforce strict or= loose source routing semantics? ok, now I see your point. Sorry for being slow. The behavior is determined by the SID. Each node advertises its SIDs. Each SID is associated with a semantic (strict or loose). In SR-MPLS you ad= vertise labels as: . Prefix/Node-SIDs: these have the "loose" semantic. . Adjacency-SIDs: these have the "strict" semantic. In SR-IPv6 we do the same: . IPv6 prefix: "loose" semantic. . IPv6 prefix with a (new) flag: "strict" semantic. Example:=20 . NodeA and NodeB are connected through interface X which has prefix P . No= deA and NodeB advertise prefix P with a flag (in SR subTLV) stating the "strict" semantic is used if such prefix is found in the segment list as active segment. . Any node in the network can now send a packet with following segment list: .

I don't think the fib needs to know anything about loose or strict. the router does: .advertise in isis/ospf a SID assigned to an interface: the adj-sid=20 .create a fib entry for that sid. The fib "outgoing interface" is the=20 interface the adj-sid is assigned to. when a packet is received with an active sid being the adj-sid, it is=20 forwarded to the interface of the fib entry. The result is that the=20 adj-sid allows you to forward to an interface regardless your shortest=20 path tree. s. =20 > If so, are any other new attributes included in the FIB entry?

Section 2.3 (IPv6 Segment Routing in the Data Center) of draft-martin-spring-segment-routing-ipv6-use-cases talks about using Segment Routing for service chaining. Please note that the SFC WG charter calls for the SFC WG to determine the data plane behavior and the requirements on the control plane in support of service chaining. Therefore, until the SFC WG determines the data plane behavior and the control component requirements for service chaining, presenting service chaining as a use case for IPv6 Segment Routing header is premature.

Section 3 of draft-previdi-spring-problem-statement presents IGP-based MPLS tunnels as a use case for SPRING. Since SPRING is about source/explicitly routed tunnels, then the use case of IGP-based tunnels is outside the scope of SPRING. After all, these IGP-based tunnels are *not* source/explicitly routed.

To illustrate this point just look at Section 5 of the draft: Section 5 - Traffic Engineering. The SPRING architecture should support traffic engineering, including: o loose or strict options o bandwidth admission control o distributed vs. centralized model (PCE, SDN Controller) o disjointness in dual-plane networks o egress peering traffic engineering o load-balancing among non-parallel links o Limiting (scalable, preferably zero) per-service state and signaling on midpoint and tail-end routers. o ECMP-awareness o node resiliency property (i.e.: the traffic-engineering policy is not anchored to a specific core node whose failure could impact the service. The SPRING use case document has to elaborate each use case in sufficient details that we could each read it and agree on how the functionality would be accomplished, but without describing the actual solutions. This applies not just to Section 5, but to the whole document. Yakov.

This draft covers more than just use cases, but describes a solution. E.g., in section 2: This is achieved by resetting the B-flag in the related AdjSID's as per the IGP extensions defined in [3]. and in section 3: An SR solution aimed at supporting these requirements is defined in [2]. and in section 5: Let us illustrate this for adjacency segments with the following example. o Node C is configured with 3 adjacency segments for the connected interface to D: AdjSID(CD1), AdjSID(CD2) and AdjSID(CD3) o SR Flow F1: from A to E over segment list {NodeSID(C), AdjSID(CD1), NodeSID(E)} o SR Flow F2: from F to I over segment list {NodeSID(C), AdjSID(CD2), NodeSID(I)} o SR Flow F3: from G to Z over segment list {NodeSID(C), AdjSID(CD3), NodeSID(Z)} o Node C is configured with a distinct protection technique for each adjacency segment. AdjSID(CD1) is configured without protection, AdjSID(CD2) is configured to benefit from management-free local protection and AdjSID(CD3) is configured for managed local protection over the path {AdjSID(CH), AdjSID(HD)} Such a co-existence is partially supported by the SR IGP extensions [ref tbd] o Multiple adjacency segments can be advertised for the same adjacency o The non-protected property of AdjSID(CD1) is signalled by a reset B flag. o The protected property of AdjSID(CD2) and AdjSID(CD3) are signalled by a set B flag. The SR IGP extension should be extended to discreminate between AdjSID(CD2) and AdjSID(CD3). A single flag could be defined (managed path vs fully automated). The SPRING resiliency use case document has to elaborate each use case in sufficient details that we could each read it and agree on how the functionality would be accomplished, but without describing the actual solutions.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 24 Mar 2014 19:20:25 -0000 I disagree. There is nothing wrong to present a use case for service chaining either in SPRING WG with draft-martin-spring-segment-routing-ipv6-use-cases or for that matter in IDR with draft-patel-raszuk-bgp-vector-routing-01 or draft-rfernando-l3vpn-service-chaining-03 at present time. Holding work and proposals till SFC WG will deliver a new data plane encapsulation and new control plane solution while existing or shipping protocols are already providing or can be easily extended to provide service chaining seems rather like artificial politics and not a real technical IETF argument. IMO it would be much better if we would all focus on technical details of the use cases documents and proposed protocol extensions rather then enforcing serialization delay of work between various WGs.

The definition of "source routing" states that source routing is the ability which allows a sender of a packet to partially or completely specify the route the packet takes through the network Let's notice that it says nothing about the src of such information. Such source of this information can be coming from various sources or routing protocols including IGPs. Charter says: " Full explicit control (through loose or strict path specification) can be achieved in a network comprising only SPRING nodes, however SPRING must inter-operate through loose routing in existing networks and may find it advantageous to use loose routing for for other network applications." The above quite directly allows SPRING WG to work on "loose paths" and "loose routing" therefor IGPs can be used just fine to propagate such explicit control information. Thx, R.

Without explicitly mentioning who/how many they are. We have some operators as co-authors, but not all the operators we have bee= n working with participate at the IETF.

I tend to agree with you and my first approach was to take the=20 segment routing use cases draft, spoil it from any solution=20 description, and publish it as spring-use-case-prolem-statment.

In such scenarios a non-MPLS based solution would be required. The above assumes that the already available technology, MPLS, "may not be available or deployable for lack of support on network elements", yet a brand new technology, a new IPv6 Segment Routing header, will be available, deployable, and supported on network elements. The authors should elaborate on what makes them think so. Wrt "for an operator's design choice", the draft should present a rational explanation for such choice. Otherwise, the draft should just say that its use cases are the folks who go into anaphylactic shock at the mention of MPLS. More from section 2: 4. There is a need to connect millions of addressable segment endpoints, thus high routing scalability is a requirement. IPv6 addresses are inherently summarizable: a very large operator could scale by summarizing IPv6 subnets at various internal boundaries. This is very simple and is a basic property of IP routing. MPLS node segments are not summarizable. Where is the use case that illustrates application of summarizable Node-SIDs ? To reach the same scale, an operator would need to introduce additional complexity, such as mechanisms described in [I-D.ietf-mpls-seamless-mpls] Perhaps before claiming "additional complexity" in [I-D.ietf-mpls-seamless-mpls] the authors of the draft should count the number of times the word "simple" or "simplicity" occurs in [I-D.ietf-mpls-seamless-mpls] (which btw has one of its authors the same as one of the authors of draft-martin-spring-segment-routing-ipv6-use-cases).

The authors should elaborate on what makes them think so. Let's observe that in order to encapsulate traffic in MPLS in 1000 node network and steer it north and south 1000 nodes need to be able to support MPLS (or for that matter RSVP-TE and IGP extensions - let's leave aside inter-area problems). Contrary if the desire is to steer traffic via north and south nodes from given ingress node to egress node only those 4 out of those 1000 nodes need to support segment routing. Non of the transit nodes needs to be SR aware. I think this makes the deployment and operational difference very clear. r.

Yakov,

The topic here is traffic controll and traffic steering. In = MPLS to the best of my knowledge the only tool to accomplish that is MPLS T= E.

That in turn requires RSVP-TE and pretty heavy IGP extension= s.

I=A0 am not aware of any deployments of the above MPLS contr= ol planes over GRE nor I am aware of using those when only subset of nodes = in your domain supports required extensions.

If however you are pointing out that to replace LDP one can = use GRE I completly agree.

Thx,
R.

The ability to carry MPLS over transit nodes that are not MPLS aware
is an already solved problem - it is called MPLS-over-GRE (rfc4023).
Implemented by multiple vendors. Known to be interoperable.

Alvaro,

 

Section 3 of draft-previdi-spring-problem-statement presents as follows:=

 

"  The source-based routing model, applied to the MPLS datapla= ne, offers
   the ability to tunnel services (VPN, VPLS, VPWS) from an ingre= ss PE
   to an egress PE, without any other protocol than IGPs (ISIS or= OSPF).
   LDP and RSVP-TE signaling protocols are not required."

 

In my opinion, now the IP network is alway to bear multiple services inc= luding unicast and mulitcast. Then LDP does not only mean RFC 5036, but RFC= 5036 and mLDP. RSVP-TE does not only mean RFC 3209, but RFC 3209 and P2MP = TE. If SR path does not cover multicast, "LDP and RSVP-TE signaling protocols are not required" is just t= o mislead.  

 

 

Regards,

Zhenbin(Robin)

To me this paragraph above is the real justification for use of IPv6.

On the one hand as far as I know the MPLS data plane has not been depl= oyed in home networks -- although to be fair just how my digital cable box = and my digital telephone box talk with the network is a detail that I don't= need to know and in my role as a homeowner I don't want to know. Also the = data speeds needed in the home network might be slow enough that purely sof= tware forwarding might be appropriate (at least for now).=20 Section 2.2 ("IPv6 Segment Routing in the Access Network") seems to me to b= e a perfectly reasonable explanation for why SPRING is useful in the access= network, along with a statement along the lines of the paragraph above (th= at some might just not want to use an MPLS data plane).=20 The same could be said for sections 2.3, 2.4 and 2.5, which contain perfect= ly reasonable explanations for why SPRING might be useful in Data Centers, = Content Delivery Networks, and Core Networks. However, why the data centers= , content delivery networks, and core networks might want to use SPRING, an= d whether they choose to use an MPLS forwarding plane or an IPv6 forwarding= plane, seem like independent issues. Given that a SPRING control plane sho= uld be able to work just fine with either data plane, the choice of data pl= ane might come down to issues such as what products get built and what perf= ormance can be achieved at what cost.

Alvaro,

 

Section 3 of draft-previdi-spring-problem-statement presents as follows:=

 

"  The source-based routing model, applied to the MPLS datapla= ne, offers
   the ability to tunnel services (VPN, VPLS, VPWS) from an ingre= ss PE
   to an egress PE, without any other protocol than IGPs (ISIS or= OSPF).
   LDP and RSVP-TE signaling protocols are not required."

 

In my opinion, now the IP network is alway to bear multiple services inc= luding unicast and mulitcast. Then LDP does not only mean RFC 5036, but RFC= 5036 and mLDP. RSVP-TE does not only mean RFC 3209, but RFC 3209 and P2MP = TE. If SR path does not cover multicast, "LDP and RSVP-TE signaling protocols are not required" is just t= o mislead.  

 

 

Regards,

Zhenbin(Robin)

Alvaro,

 

Section 2 of draft-francois-spring-resiliency-use-case presents as = follows:

 

" 
   From an SR viewpoint, we would like to highlight the following=
   requirement: the adjacency segments used to support the tunnel= s T1
   and T2 MUST NOT benefit from local protection.  This is a= chieved by
   resetting the B-flag in the related AdjSID's as per the IGP    extensions defined in [3].
"

 

It is too detailed to define like "This is achieved by resetti= ng the B-flag in the related AdjSID's as per the IGP   extensions= defined in [3]". The use case should be defined well instead of = protocol procedures.

Hi Robin,

Please notice that mLDP and LDP have nothing in common as fa= r as protocol itself. So those are two separate protocols.

The name may be confusing ;)

Section 3 of draft-previdi-spring-problem-statement presents as follows:=

=A0

"=A0 The source-based routing model, applied to the MPLS dataplane,= offers

In my opinion, now the IP network is alway to bear multiple services inc= luding unicast and mulitcast. Then LDP does not only mean RFC 5036, but RFC= 5036 and mLDP. RSVP-TE does not only mean RFC 3209, but RFC 3209 and P2MP = TE. If SR path does not cover multicast, "LDP and RSVP-TE signaling protocols are not required" is just t= o mislead. =A0

Alvaro,

 

Section 2 of draft-martin-spring-segment-routing-ipv6-use-cases pre= sents as follows:

 

"

     4.  There is a need to connect millions of= addressable segment
       endpoints, thus high routing scalabili= ty is a requirement.  IPv6
       addresses are inherently summarizable:= a very large operator
       could scale by summarizing IPv6 subnet= s at various internal
       boundaries.  This is very simple = and is a basic property of IP
       routing.  MPLS node segments are = not summarizable.  To reach the
       same scale, an operator would need to = introduce additional
       complexity, such as mechanisms describ= ed in
       [I-D.ietf-mpls-seamless-mpls]

"

 

Comments is as follows: 

1. I wonder why here mention the comparison with seamless MPLS. The= y are totally different scenarios. Do authors think that if the whole = seamless MPLS network changes to only use IPv6, there will not be addtional= complexitiy comparing with seamless MPLS?

2. MPLS label can also be allocated to the subnet IP address. In my opin= ion, it is summarizable. MPLS is not summarized because the service need th= e LSP to host IP address. But this does not mean MPLS are not summarizable.= Could you please clarify what it mean "MPLS node segments are not summarizable"?

 

Regards,

Zhenbin(Robin)

How do you summarize subnet 10.1.1.0/24 with label 1001 through subnet 10.1.254.0/24 with label 1254 at any given point in the network ? What is the resulting label for 10.1.0.0/16 ? And how does the resulting label lookup provides sufficient information for swap operation without additional IP lookup ? That's what industry means by stating that MPLS scaling is limited due to inherent lack of summarization. Best, R.

So those are two separate protocols. To put some reality check on your claim, and especially on the part that "mLDP and LDP have nothing in common as far as protocol itself", let me point out the following from Section 1 of rfc6388 ("Label Distribution Protocol Extensions for Point-to-Multipoint and Multipoint-to-Multipoint Label Switched Paths"): This document describes extensions to LDP for setting up point-to-multipoint (P2MP) and multipoint-to-multipoint (MP2MP) LSPs.

Please notice that mLDP and LDP have nothing in common as f a= > r as protocol itself. So those are two separate protocols.

Hi Robert,=

 = ;

I think Ya= kov=A1=AFs point could be interpreted as =A1=B0you can use MPLS-SR in conju= nction with MPLS-over-GRE to realize the goal that you have mentioned, i.e., only those 4 out of those 1000 nodes need to support segment routing= . None of the transit nodes needs to be SR aware=A1=B1. For more details, p= lease see http://tools.ietf.o= rg/html/draft-xu-spring-islands-connection-over-ip and http://www.ietf.org/proceedings/89/slides/slides-89-spring-0.pptx

Yakov,

The topic here is traffic controll and traffic stee= ring. In MPLS to the best of my knowledge the only tool to accomplish that = is MPLS TE.

That in turn requires RSVP-TE and pretty heavy IGP = extensions.

I  am not aware of any deployments of the abov= e MPLS control planes over GRE nor I am aware of using those when only subs= et of nodes in your domain supports required extensions.<= /p>

If however you are pointing out that to replace LDP= one can use GRE I completly agree.

Thx,
R.

The ability to carry MPLS over transit nodes that are not MPLS aware
is an already solved problem - it is called MPLS-over-GRE (rfc4023).
Implemented by multiple vendors. Known to be interoperable.

Yakov.

But what does this buy you if you already have dual stack network which most operators already do for years ? For clarity I do not consider as sufficient reason fear from one going into anaphylactic shock at the mention of IPv6 as a valid one. Cheers, R.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 28 Mar 2014 09:21:51 -0000 Hi Yakov, If we are to talk real - let's do it. mLDP is effectively subset of PIM control plane enhanced to carry MPLS labels over LDP transport. Unicast LDP control plane procedures have as I said in my former mail in vast majority nothing in common with mLDP and vice versa. And I am talking about real implementations and not RFCs. If you call using completely different protocol and stuffing it under LDP umbrella as (LDP extension) that's clearly your choice. But for the SPRING WG point what matters is that when one can use segment routing to remove need of unicast LDP it does not mean that segment routing also needs to artificially rename and assimilate PIM to claim both unicast and multicast coverage. In IP networks multicast has already number of practical solutions on the table to control construction of its distribution trees that I do not think "extensions" of segment routing are required in this space at least in this point of time. Perhaps it would be productive to check with others in SPRING WG both operators and vendors on their opinion in this matter. Yours, Robert.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 28 Mar 2014 09:49:34 -0000 Hi Xu, Today MPLS over GRE support in most implementations I am familiar with has been supported for applications using MPLS labels as demux to VRFs (example L2 or L3 VPNs). It is not directly obvious that one can claim support for transport MPLS as SID over GRE on existing deployed hardware without requirement to change existing data plane. I mean of course line rate support in line cards rather then punting it to slow path. After all the switching path needs to support following sequence of operati= on: - Decapsulation of GRE header - POP - Lookup subsequent MPLS label as SID in global table - Encapsulation in GRE + MAC rewrite Clearly software upgrade is needed anyway to support SR, but I think you are making a claim that v6 data plane support will be much harder then the above. I think the answer really depends on the particular hardware used. Regards, R.

This draft is a work item of the Source Packet Routing in Networking Working Group of the IETF. Title : SPRING Problem Statement and Requirements Authors : Stefano Previdi Clarence Filsfils Bruno Decraene Stephane Litkowski Martin Horneffer Ruediger Geib Rob Shakir Robert Raszuk Filename : draft-previdi-spring-problem-statement-01.txt Pages : 19 Date : 2014-03-28 Abstract: The ability for a node to specify a forwarding path, other than the normal shortest path, that a particular packet will traverse, benefits a number of network functions. Source-based routing mechanisms have previously been specified for network protocols, but have not seen widespread adoption. In this context, the term 'source' means 'the point at which the explicit route is imposed'. This document outlines various use cases, with their requirements, that need to be taken into account by the Source Packet Routing in Networking (SPRING) architecture. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-previdi-spring-problem-statement/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-previdi-spring-problem-statement-01 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-previdi-spring-problem-statement-01 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

We will rework the segment routing use cases draft in order not to have duplicated text. Hope this will increase the substantial consensus=20 draft-previdi-spring-problem-statement already has.

Please note that the reason why "the operator AS1 can not apply" the traffic-engineering policy listed above is due to the assumptions made above. To allow the operator of AS1 to apply the traffic-engineering policy listed above, all you need is to revise the assumptions as follows: C in AS1 learns about destination Z of AS 4 via two BGP paths (AS2, AS4) and (AS3, AS4) C does not set next-hop-self before propagating the paths within AS1 (next-hop is still D or E) C propagates all the paths to Z within AS1 (add-path). C originates into AS 1 BGP route to D with C as next-hop and label L1 C originates into AS 1 BGP route to E with C as next-hop and label L2 Both A and B have a hop-by-hop LSP to C (signaled with either LDP or RSVP-TE); A uses label L-A-C, B uses label L-B-C No MPLS outside of AS1 is needed (no MPLS on C-D and C-E links) With these assumptions the policy mentioned above is implemented as follows: Steer 60% of the Z-destined traffic received at A via AS2 and 40% via AS3: By A using label stack for 60% of the Z-destined traffic, and label stack for 40% of the Z-destined traffic Steer 80% of the Z-destined traffic received at B via AS2 and 20% via AS3: By B using label for 80% of the Z-destined traffic, and label stack for 20% of the Z-destined traffic With this in mind the authors of the draft should also document the revised assumptions, as well as the conclusion based on these revised assumptions.

Nor we have much of deployments of IPv6 only control + data plane which supports MPLS. And IPv6 only networks are real not imaginary. So there are two options: - add minor extensions to IPv6 dataplane which can provide control and encapsulation in a very smooth and gradual way for a number of applications - rework, implement and deploy entire load of MPLS control plane to support IPv6 bearing in mind that MPLS does not have real NNI so at best it's applicability is limited to closed domains under same administration At least to me the above choice is clear.

I am of the opinion that this is a question of having hardware complaint to RFC6564 recommendation of IPv6 Extension Header Format which has been around for few years as IETF standards track document. Clearly if your hardware is not complaint with recommended format of any new EH your claim is true. However it seems to me (no matter how great IPv4+MPLS data plane feature richness is today) that freezing support for current and future enhancements in IPv6 is a dead end street for both vendors and operators. I guess it is ok for market to decide, but it does not seems to be ok for IETF politics to make such call. > just curious - whats wrong with BGP-LU, BGP-LS as a NNI protocol ? Nothing wrong, but those are limited to a same trust domain. While BGP SAFI 2/1 is a bit of much wider deployment scope. Cheers, R.

Well looking from the side at this I think perhaps both parties are a bit too far. As example one side is defending LDP unicast like it's of any practical value, while the other side dismisses use of simple GRE encapsulation and proposes in place SR. Looking at the bigger picture it needs to be observed that networks are becoming simpler and are moving to carry less state while more and more services are becoming overlays. With that in mind keeping use of entire load of MPLS control plane state is not aligned with network re-architecture trend. Example: Peter's TeraStream ... look how much MPLS control plane state he is carrying in the Croatia network and draw your own conclusions ;) Of course in the case of SR shifting the state to centralized controllers responsible for inserting proper headers in the packets does not come for free and there is still a lot to be done on the management, monitoring and troubleshooting side, but if we rather then working on this will continue to argue about MPLS and it's signalling being the only multi-protocol data plane forever we may not get far I am afraid - but maybe that's the point ..... > | Nothing wrong, but those are limited to the same trust domain.

In theory it is not, however in practice it is sufficient to observe how many tier1s, tier2s or even tier3s ISPs and IX-es run 3107 peering sessions today to answer your dilemma. Cheers, R.

As you know the IP6 header chaining has not been designed for making hardware lookups efficient. it may well be that because of the potential 100s of additional routing header bytes the firewall relevant data cannot be accessed hy the lookup engine, which typically has got a limited view on the header bytes. this is a example of "not telling the full truth" ... (again no insult) it may be that you can do the routing lookups, but can you do all together at *scale* ? 1) processing large routing headers 2) firewall lookups 3) at line rate 4) more than one chipset family 5) differwnt chipset generations | > just watch your installed base in your co-authoring SP networks (core, edge, DC) | > and ask yourself if the hardware upgrade in support of v6-sr is | > zero cost or > zero-cost and then look how big the upgrade cost is | > and then it becomes obvious that this cannot be glossed over. | | | do you really think we didn't do the exercise ? i don't know - if i just look at the cost of supporting this on a installed base e.g. two different ASIC families and two different generations thereof, plus teh full feature matrix and senior testers which will squeeze the product i'll get very fast at discomfort. | Also, do you really think we are planning to do a forklift upgrade of all network | elements because of SR-IPv6 ? no usually it works such that you: 1. try to insert this at the edge first (this adds value for an immediate customer requirement) and therbet carefully hiding the future cost of this (at high speed) in the core. 2. when SPs want to enable it at the core / higher speeds / other platforms the true cost unveils. | I think I explained multiple times but | just in case: SR-IPv6 requires the node processing the SRH to be | capable of so, not the entire network. understood, arguable the same (loose source routing) can be achieved e.g. with nested GRE tunnels ... there is no need to add an entirely new dataplane. | Bottom line, we do have HW that does not incur a substantial (nor | significant) penalty because of EHs.

LDP and RSVP-TE signaling protocols are not required." The above claim about the ability to tunnel services "without any other protocol than IGPs" is misleading, as VPN and VPLS services may use p2mp LSPs, and neither ISIS nor OSPF provide any capability for setting up such LSPs. Moreover, the claim about "LDP and RSVP-TE signaling protocols are not required" is misleading as well, as p2mp LSPs are signaled using either mLDP (which is build as an extension to LDP) or RSVP-TE. Zhenbin(Robin) pointed to this in his e-mail (see http://www.ietf.org/mail-archive/web/spring/current/msg00727.html) Furthermore, the above claim is incorrect if the ingress and egress PEs are in different autonomous systems.
