Hi Gyan, as a DT member, I can answer your analysis draft question. Consistent with the requirement document, proposals were analyzed with 16-bit and 32-bit SID lengths, though several supported additional options. The CSID draft recommended NEXT-C-SID use for 16-bit C-SIDs, and REPLACE-C-SID use for 32-bit C-SIDs. The design team followed this recommendation in its analysis, though the CSID draft notes all flavors support both 16-bit and 32-bit C-SID length. Darren

The C-SID draft has 3 compression solutions below and is a combination of the two drafts below which introduces 2 of the 3 compression solutions with the C-SID draft introduction of yet a 3rd compression solution. Which of the 3 C-SID draft compression solutions was included as part of the DT analysis draft results and conclusion? This is a critical question that needs to be answered for clarification on the C-SID draft solution. As the WG has consensus on a single solution we need to have clarification from the authors which of the 3 compression solutions was included in the analysis. The three solutions are very different and all would yield different analysis results. I understand the authors have called the each solution a endpoint flavor which I see from the IANA codepoint allocations, however each flavor is a different solution. https://www.iana.org/assignments/segment-routing/segment-routing.xhtml So the WG as stated would like a single solution so now we need feedback from the authors which of the three solutions or endpoint flavors was part of the DT analysis draft that the authors would like to put forward as the single compression solution. C-SID is a combination of the two drafts below: Combination of the two drafts below: G-SID - Generalized SID “REPLACE-C-SID” https://datatracker.ietf.org/doc/html/draft-cl-spring-generalized-srv6-for-cmpr-03 SRv6 uSID micro-segment “ NEXT-C-SID” https://datatracker.ietf.org/doc/html/draft-filsfils-spring-net-pgm-extension-srv6-usid-10 Kind Regards Gyan -- [http://ss7.vzw.com/is/image/VerizonWireless/vz-logo-email]<http://www.verizon.com/> Gyan Mishra Network Solutions Architect Email [email protected]<mailto:[email protected]> M 301 502-1347
