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.

This document is a product of the Multiprotocol Label Switching Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
