Folks,

This reminds me. What happened to REQ-7-24-ipv6-based? Was that dropped unintentionally?

Folks,

Is RFC 8663 really a compression proposal? It requires all of the segment endpoints to be MPLS aware?

                                                                                      Ron

Here is my summary of drafts for reading and analysis:

draft-filsfilscheng-spring-srv6-srh-comp-sl-enc

  *   Documents SRv6 SID behaviors to support  compression, combining SIDs from:

     *   draft-filsfils-spring-net-pgm-extension-srv6-usid (SRv6 uSID)
     *   draft-cl-spring-generalized-srv6-np (SRv6 GSID)

draft-decraene-spring-srv6-vlsid

  *   Documents a new or modified routing header for compression and how to build SRv6 SIDs

draft-bonica-6man-comp-rtg-hdr

  *   Documents new routing headers and a label map to IPv6 address and behavior

draft-mirsky-6man-unified-id-sr

  *   Documents a new or modified routing header with variable length segments and a label map to IPv6 address and behavior

RFC8663

  *   Documents SR MPLS over IP(v6), a label mapped to IPv6 address and behavior.

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
-          draft-filsfils-spring-net-pgm-extension-srv6-usid

Can anybody think of any others.

                                              Ron
