       Service Chaining using Unified Source Routing Instructions
                   draft-xu-mpls-service-chaining-03

Abstract

   Source Packet Routing in Networking (SPRING) WG is developing an MPLS
   source routing mechanism.  The MPLS source routing mechanism can be
   leveraged to realize a unified source routing instruction which works
   across both IPv4 and IPv6 underlays in addition to the MPLS underlay.
   This document describes how to leverage the unified source routing
   instruction to realize a transport-independent service function
   chaining by encoding the service function path information or service
   function chain information as an MPLS label stack.
