An MPLS-Based Forwarding Plane for Service Function Chaining
RFC 8595, “An MPLS-Based Forwarding Plane for Service Function Chaining”, is a Proposed Standard document published in June 2019 by A. Farrel, S. Bryant, J. Drake. The canonical text is published by the RFC Editor.
Abstract
This document describes how Service Function Chaining (SFC) can be achieved in an MPLS network by means of a logical representation of the Network Service Header (NSH) in an MPLS label stack. That is, the NSH is not used, but the fields of the NSH are mapped to fields in the MPLS label stack. This approach does not deprecate or replace the NSH, but it acknowledges that there may be a need for an interim deployment of SFC functionality in brownfield networks.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
