Dear WG,
This revision includes significant text changes following the continuous and very constructive feedback that we received from many WG participants. A summary of the changes is provided below. The authors will also send separate emails with further detail on the most important text changes. - Following feedback from Gyan and others [1], renamed and expanded Sec. 7 (was: Efficient SID-list Encoding; now: SR Source Node) and Sec. 9 (Control Plane) to describe the method by which an SR source node may leverage the SID flavors in this document to encode a compressed SRv6 Segment List in the SRH. - Following offline feedback from WG participants before and during IETF 116, expanded Sec. 4 to specify the C-SID flavors applicability to the other SR intermediate endpoint behaviors in RFC 8986, namely End.T, End.B6.Encaps, End.B6.Encaps.Red, and End.BM. Updated the IANA consideration accordingly. - Following comments from Qiangzhou and other WG participants before IETF116, modified REPLACE-C-SID flavor for End and End.X (argument format and packet processing when the next C-SID value is 0). - Added End.DX* and End.DT* for REPLACE-C-SID flavor. - Following numerous questions from WG participants and implementers, added Sec. 6.4 with guidelines for installing C-SID flavored SIDs in FIBs. - For the same reason, also added the complete pseudocodes for End with NEXT-C-SID and End with REPLACE-C-SID in Appendix B. - Added new implementation reports received by the authors since the last revision (Nokia, Arrcus, Marvell, Broadcom, ZTE, H3C, and Ruijie Network). - NEXT-and-REPLACE-C-SID was removed from this version of the draft due to lack of implementation. - Various editorial fixes and addition of a new contributor. The authors would like once again to thank everyone who provided feedback or contributed text to this document. Thanks, Francois (on behalf of the C-SID co-authors) [1]: https://mailarchive.ietf.org/arch/msg/spring/aw56JRv8hPbRZEByguBaVZSNQBs/ On Fri, Mar 31, 2023 at 11:29 PM <internet-dra...@ietf.org> wrote: > > A New Internet-Draft is available from the on-line Internet-Drafts > directories.
