A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Source Packet Routing in Networking WG of the IETF. Title : Integration of Network Service Header (NSH) and Segment Routing for Service Function Chaining (SFC) Authors : James N Guichard Jeff Tantsura Filename : draft-ietf-spring-nsh-sr-06.txt Pages : 17 Date : 2021-06-08 Abstract: This document describes the integration of 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. The integration described in this document demonstrates that NSH and SR can work jointly and complement each other leaving the network operator with the flexibility to use whichever transport technology makes sense in specific areas of their network infrastructure, and still maintain an end-to-end service plane using NSH.
