Weiqiang,

Text quoted below from the SPRING charter indirectly covers Point-to-Multipoint requirement which is addressed by SR Replication Segment draft https://datatracker.ietf.org/doc/draft-ietf-spring-sr-replication-segment/

New types of segments mapping to forwarding behaviour (e.g., local
ingress replication, local forwarding resources, a pre-existing
replication structure) if needed for new usages.

For the Point-to-Multipoint compression requirement, what exactly is "multicast address" in the Metric? Is this an IPv6 multicast address? If so, it really does not conform to SRv6 data plane. 

 

I would rather consider the SRv6 Replication SID, described in the latest version of SR Replication segment draft, to be the Metric for measuring P2MP requirement. Maybe we should also consider adding it to SRv6 Functionality Section 4.2.1 of the compression requirements draft.

Hi All,

Two drafts have been submitted.  Please review them and any comments are welcomed.

 

Compression requirement draft -04 version provided two more requirements:

Compression analysis draft -00 provided a skeleton for the analysis of 4 candidate proposals.
