Hi SPRING WG co-chairs, We authors believe this draft (https://tools.ietf.org/html/draft-xuclad-spring-sr-service-chaining-01) has been stable enough and therefore we would like to request a WG adoption call for it.
We believe this work belongs to SPRING WG since the concept of service segment has been mentioned in the Segment Routing architecture from day one and the approaches as described in this draft are exactly to leverage the stateless source routing capability of segment routing to achieve a stateless SFC. To some extent, SFC can be looked as a special case of source routing as it requires the selected traffic to traverse an ordered list of service nodes. We believe the SFC WG review is still needed after the adoption since we still hope to reuse the NSH for some special purposes (e.g., use it as a metadata container). BTW, implementations based on this draft have existed, as noted in section 8 of the draft. Best regards, Xiaohu (on behalf of coauthors)
