Good summary. I also have concerns on RFC8663. It was not designed for compression. B.R.

However, the second draft defines the architecture of G-SRv6, while the first draft defines the G-SRv6 for compression as we can see it from the name of the drafts. Therefore, they are a single solution. Also, the third draft describes three types of solutions including G-SRv6, Micro SID and combination. Therefore, they are mainly two proposals in the links you proposed: G-SRv6 and Micro Segment. In summary, we already have multiple proposals as listed below: ・ G-SRv6 (One option in native SRv6 compression) ・ Micro SID(One option in native SRv6 compression) ・ V-SID(draft-decraene-spring-srv6-vlsid) ・ CRH(draft-bonica-6man-comp-rtg-hdr) ・ U-SID (draft-mirsky-6man-unified-id-sr) Thanks, Cheng From: Srcomp [mailto:srcomp-bounces@ietf.org] On Behalf Of James Guichard Sent: Thursday, January 21, 2021 2:25 AM To: Ron Bonica <rbonica=40juniper.net@dmarc.ietf.org>; srcomp@ietf.org Subject: Re: [Srcomp] Compression proposals Hi Ron, There are several. https://www.ietf.org/archive/id/draft-cl-spring-generalized-srv6-for-cmpr-02 .txt https://www.ietf.org/archive/id/draft-cl-spring-generalized-srv6-np-02.txt https://www.ietf.org/archive/id/draft-filsfilscheng-spring-srv6-srh-comp-sl- enc-02.txt Jim From: Srcomp <srcomp-bounces@ietf.org> On Behalf Of Ron Bonica Sent: Wednesday, January 20, 2021 10:03 AM To: srcomp@ietf.org Subject: [Srcomp] Compression proposals Folks, The following are a few compression proposals: - draft-decraene-spring-srv6-vlsid - draft-bonica-6man-comp-rtg-hdr - draft-mirsky-6man-unified-id-sr - draft-filsfils-spring-net-pgm-extension-srv6-usid Can anybody think of any others.
