The IESG has approved the following document: - 'Integration of Network Service Header (NSH) and Segment Routing for Service Function Chaining (SFC)' (draft-ietf-spring-nsh-sr-14.txt) as Proposed Standard
This document is the product of the Source Packet Routing in Networking Working Group. The IESG contact persons are Jim Guichard, Andrew Alston and John Scudder. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-spring-nsh-sr/ Technical Summary This document describes the integration of the Network Service Header (NSH) and Segment Routing (SR), as well as encapsulation details, to support Service Function Chaining (SFC) in an efficient manner while maintaining separation of the service and transport planes as originally intended by the SFC architecture. Combining these technologies allows SR to be used for steering packets between Service Function Forwarders (SFF) along a given Service Function Path (SFP) while NSH has the responsibility for maintaining the integrity of the service plane, the SFC instance context, and any associated metadata. This integration demonstrates that NSH and SR can work cooperatively and provide a network operator with the flexibility to use whichever transport technology makes sense in specific areas of their network infrastructure while still maintaining an end-to-end service plane using NSH. Working Group Summary There were a number of comments on this document through the last call, but the comments were all addressed during the last call through multiple revisions of the document. Document Quality There are no implementations or implementation plans that have been publicly shared. All in all I found the document to be clear and well drafted.
