Source Packet Routing in Networking (SPRING) WG specifies a special source routing mechanism. Such source routing mechanism can be leveraged to realize the service path layer functionality of the service function chaining (i.e, steering traffic through a particular service function path) by encoding the service function path or the service function chain information as the explicit path information. This document describes how to leverage the MPLS-based source routing mechanism as developed by the SPRING WG to realize the service path layer functionality of the service function chaining.
