MPLS Transport Encapsulation for the Service Function Chaining Network Service Header

Overview

RFC 8596, “MPLS Transport Encapsulation for the Service Function Chaining Network Service Header”, is an Informational document published in June 2019 by A. Malis, S. Bryant, J. Halpern, W. Henderickx. The canonical text is published by the RFC Editor.

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.
