Hey Wim,

 

Thanks for (not 😉 ) reading.

 

Yes, MPLS-SFC was certainly in mind, but we wrote the initial document only for NSH, and so the document is named for that and fully scoped for that.

 

I believe that draft-ietf-mpls-sfc-encapsulation is “only” an interface encapsulation of NSH. Thus if we support NSH (we do, and we describe it), and if we support identifying the interface “tunnel type” (we do because this is a standard extension for BGP and we talk about it in the draft), I think we have that document covered.

 

I haven’t read draft-guichard-spring-nsh-s (yet), but it might be a bit premature to include an applicability discussion of that work before it is adopted by SPRING.

 

BUT, I certainly have no objection to someone (you?) starting one or more applicability documents.

 

Ciao,

Adrian

 

Oh! John just sent almost the same email!

I need to get into more details, but the current draft is written with draft-ietf-mpls-sfc-04 dataplane in mind. I believe that the draft can be useful with other dataplanes like: draft-ietf-mpls-sfc-encapsulation and draft-guichard-spring-nsh-s


So I would like the see the BGP control plane extensions here to become more generic to support multiple data-planes options. I need to go in more detail, but from high level this is my feedback here. I don’t want to stop/block this work as I believe this is a very useful proposal, but if we make it more generic it can serve a bigger purpose.

 

So I would like to see the following:

1.	Protocol draft
2.	Use case drafts for the different data planes.

 

My 2 cents.

Subject: [bess] WGLC, IPR and implementation poll for draft-ietf-bess-nsh-bgp-control-plane

 

Hello Working Group,

    

This email starts a three weeks Working Group Last Call on  draft-ietf-bess-nsh-bgp-control-plane [1]. 

 

This poll runs until *the 4th of February*.

 

We are also polling for knowledge of any undisclosed IPR that applies to this Document, to ensure that IPR has been disclosed in compliance with IETF IPR rules (see RFCs 3979, 4879, 3669 and 5378 for more details).

If you are listed as an Author or a Contributor of this Document please respond to this email and indicate whether or not you are aware of any relevant undisclosed IPR. The Document won't progress without answers from all the Authors and Contributors.

 

We have several IPRs already disclosed.

 

If you are not listed as an Author or a Contributor, then please explicitly respond only if you are aware of any IPR that has not yet been disclosed in conformance with IETF rules.

 

We are also polling for any existing implementation as per [2]. 

    

    Thank you,

    Stephane & Matthew
