Dear Authors

After having a few discussions on threads related to the SRv6 compression
analysis draft results, as well as WG coming to consensus on a single SRv6
compression solution, a few critical questions have come up related to
C-SID draft that requires clarification by the authors.

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”
