Hi Folks,
We proposed the following draft which provide the mechanism called Compressed SRv6 Network Programming for SRv6 compression:
https://www.ietf.org/internet-drafts/draft-li-spring-compressed-srv6-np-01.txt

The relationship between G-SRv6 and C-SRv6 is explained as follows:
- For G-SRv6, it provides solutions for more scenarios besides SRv6 compression. For SRv6 compression, it provides the complete 
solutions on the basis of encapsulating Compressed SRv6 SIDs and normal SRv6 SIDs in any order in the enhanced SRH called G-SRH.
- For C-SRv6, it provides a light solution for SRv6 compression. That is, it introduces the protocol extensions as less as possible and it is 
only used for compression which only encapsulate the compressed SRv6 SID in the SRH. It can also be seen a special case of G-SRv6 for
SRv6 compression.

Until now we think there are requirements for both solutions and we will promote them together.

Your comments are welcome.

Best Regards,
Zhenbin (Robin)

Abstract:
   Segment Routing can be applied to the IPv6 data plane by leveraging a
   new type of Routing Extension Header, called Segment Routing Header
   (SRH).  However, the overhead introduced by SRH may be a challenge
   for existing hardware, which may influence on the forwarding
   performance and the payload efficiency.

   This document defines a compressed SRv6 network programming mechanism
   in order to reduce the overhead of SRv6 by introducing the Compressed
   Segment Identifier (C-SID) and the Compressed SRH (C-SRH).  The C-SRH
   can be a new Routing Header or an enhancement of SRH.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
