Was: Re: [spring] draft-filsfilscheng-spring-srv6-srh-compression-02#section-4.1.1
I’m sending this note to redirect this question to the srcomp DT for an editorial fix, when the team meets next. For the DT: Each proposal, introduced in section 1, discusses how it supports 16-bit and 32-bit SIDs. However, Gyan’s question indicates this could be more clearly stated in the analysis draft to help readers less familiar with a proposal. As such, section 1 can be improved accordingly.

In the analysis document, Tables 1 through 6 and Tables 12 through 15 each contain only one column for the CSID. They do not indicate whether the number in that column were calculated using the NEXT-C-SID, REPLACE-C-SID, or NEXT-AND-REPLACE-C-SID. (That is, the do not indicate whether they were calculated using uSID, G-SID, or a combination of both). Each of these tables should be modified, so that the CSID column is replaced by three columns (NEXT-C-SID, REPLACE-C-SID, and NEXT-AND-REPLACE-C-SID). If the numbers in these columns are different from one another, this may inform our discussion about whether NEXT-C-SID, REPLACE-C-SID, and NEXT-AND-REPLACE-C-SID are different behaviors or different flavors of a behavior.

Be cautious of content] Dear Spring Authors Please respond to this question the WG has related to which of the three SRv6 forwarding mechanisms called flavors was inclusive of the compression analysis draft. The Analysis draft is ambiguous as to which SRv6 forwarding plane flavor was part of the analysis. This is a critical question that has come up by the WG and Chairs, and answering this question will help pave the way to an adoption call for C-SID.

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<https://urldefense.com/v3/__https:/www.iana.org/assignments/segment-routing/segment-routing.xhtml__;!!NEt6yMaO-gk!XJMCrXOtpr7xttMYGJp3u6tAqsuXrjU7AVELZIzIUxBfFYjzkcL6axEYZR-kW_YB$> 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.
