   Title           : Integration of Network Service Header (NSH) and Segment Routing for Service Function Chaining (SFC)

   This document describes the integration of the Network Service Header
   (NSH) and Segment Routing (SR), as well as encapsulation details, to
   efficiently support Service Function Chaining (SFC) 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.
