Technical Summary
This document describes how to use a Service Function Forwarder (SFF)
Label (similar to a pseudowire label or VPN label) to indicate the
presence of a Service Function Chaining (SFC) Network Service Header
(NSH) between an MPLS label stack and the packet original packet/frame.
This allows SFC packets using the NSH to be forwarded between
SFFs over an MPLS network, and to select one of multiple SFFs in the
destination MPLS node.
