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. Working Group Summary The working group process has been swift and there is strong support for the document. Document Quality This informational document follows well-established MPLS procedures and does not require any actions by IANA or any new protocol extensions.
