Hi Jim,

Many thanks for your information! 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

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

Can anybody think of any others.
