Re: [spring] The SPRING WG has placed draft-voyer-spring-sr-replication-segment in state "Candidate for WG Adoption"

[Alexander Vainshtein <[e-mail]>]

Hi all,

I have a question regarding adoption of draft-voyer-sr-spring-replication-segment as a SPRING WG document.



These concerns are based on the following:

1.       This draft (both based on its title and on its content) deals with local (in the Root node) ingress replication which, in its turn, is one of the issues that could be used for delivery of multicast.

2.       Local ingress replication is mentioned in the SPRING WG Charter as one of the "New types of segments mapping to forwarding behavior". The charter further says that "Any of the above <Sasha: New types of segments> may require architectural extensions"

3.       The current (and, AFAIK, the only existing) Segment Routing Architecture document (RFC 8402<https://tools.ietf.org/html/rfc8402>) explicitly states in Section 6 that "Segment Routing is defined for unicast. The application of the source-route concept to Multicast is not in the scope of this document".

The combinations of observations above strongly suggests to me that a document defining multicast-related extensions of segment routing architecture should be very useful (if not mandatory) for progressing the Replication Segment draft. From my POV the Replication Segment draft is not (and is not intended to be) such a document.



I wonder if there is an intention to produce such a document in the timeframe that could be relevant for discussion of the Replication Segment draft.



Nothing in this message should be interpreted as my objection to (or support of) adoption of the Replication Segment draft as a WG document per se.

Bit I find it difficult to take a position any which way without a clear and commonly agreed upon framework for multicast in segment routing.



Regards,

Sasha
