    abstract =  {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.},
