Dear DT, Excellent work and many thanks to the design team to come provide the detailed analysis of the 4 proposals and how they match up with the requirements.
>From the analysis it does sound like CSID is the choice by the DT. SRv6 compression & MSD issue is now finally solved! Excellent news!! Now it’s just a matter of moving forward with CSID Adoption poll. >From the analysis it does not seem there is any draft that is in close 2nd place or a close call. >From the analysis draft the two drafts that are combined to create CSID -> I don’t see it on the Spring WG Datatracker? https://datatracker.ietf.org/doc/html/draft-srcompdt-spring-compression-analysis-02 The following mechanisms are proposed to compress the SRv6 SID list: o CSID - [I-D.filsfilscheng-spring-srv6-srh-comp-sl-enc <https://datatracker.ietf.org/doc/html/draft-srcompdt-spring-compression-analysis-02#ref-I-D.filsfilscheng-spring-srv6-srh-comp-sl-enc>] - Describes two new SRv6 SID flavors, a combination of SID flavors from [I-D.filsfils-spring-net-pgm-extension-srv6-usid <https://datatracker.ietf.org/doc/html/draft-srcompdt-spring-compression-analysis-02#ref-I-D.filsfils-spring-net-pgm-extension-srv6-usid>] and [I-D.cl-spring-generalized-srv6-for-cmpr <https://datatracker.ietf.org/doc/html/draft-srcompdt-spring-compression-analysis-02#ref-I-D.cl-spring-generalized-srv6-for-cmpr>] o CRH - [I-D.bonica-6man-comp-rtg-hdr <https://datatracker.ietf.org/doc/html/draft-srcompdt-spring-compression-analysis-02#ref-I-D.bonica-6man-comp-rtg-hdr>] - Requires two new routing header types and a label mapping technique. o VSID - [I-D.decraene-spring-srv6-vlsid <https://datatracker.ietf.org/doc/html/draft-srcompdt-spring-compression-analysis-02#ref-I-D.decraene-spring-srv6-vlsid>] - Defines a set of SID behaviors to access smaller SIDs within the SR header. o UIDSR - [I-D.mirsky-6man-unified-id-sr <https://datatracker.ietf.org/doc/html/draft-srcompdt-spring-compression-analysis-02#ref-I-D.mirsky-6man-unified-id-sr>] - Extends the SRH to carry MPLS labels or IPv6 addresses. Below 2 drafts are combined to create CSID?? https://datatracker.ietf.org/doc/html/draft-filsfils-spring-net-pgm-extension-srv6-usid-10 https://datatracker.ietf.org/doc/html/draft-cl-spring-generalized-srv6-for-cmpr-03 Kind Regards Gyan On Mon, Jul 26, 2021 at 5:53 PM Darren Dukes (ddukes) <ddukes= [email protected]> wrote: > I’ll paraphrase what I said in the call... > > > > Today the design team presented analysis of proposals to compress an SRv6 > SID list. > > They spent a year building the requirements and completing the analysis, > in depth, with unanimous consensus. > > The CSID proposal satisfied all the requirements to the largest degree of > any proposal. > > That proposal has multiple implementations, and interoperability, noted in > the draft. > > That proposal has a large set of SPRING participants working on it already. > > > > The problem of SRv6 SID list compression is solved, CSID is ready for > adoption. > > > > I hope we can conclude this, and choose a single proposal for WG adoption. > > > > Darren > > > > > > > > > _______________________________________________ > spring mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/spring > -- <http://www.verizon.com/> *Gyan Mishra* *Network Solutions A**rchitect * *Email [email protected] <[email protected]>* *M 301 502-1347*
