Dear SPRING,

The authors of draft-filsfils-spring-net-pgm-extension-srv6-usid and draft-cl-spring-generalized-srv6-for-cmpr have been working together on a joint document that describes how compressed SRv6 Segment-List encoding in the SRH can be achieved without any change to the SRv6 data plane or control plane. The new draft link is as follows:

https://www.ietf.org/internet-drafts/draft-filsfilscheng-spring-srv6-srh-comp-sl-enc-01.txt

In this draft, we leverage the notions of SID function and argument defined in draft-ietf-spring-srv6-network-programming to compress the SRv6 Segment List encoding in the SRH. The compressed encoding is achieved through two new flavors of the base Network Programming behaviors (End, End.X and End.T), named NEXT-C-SID and REPLACE-C-SID.
 
Thanks,
