Technical Summary
This document describes how Service Function Chaining can be achieved
in an MPLS network by means of a logical representation of the 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. It does not
deprecate or replace the NSH, but acknowledges that there may be a
need for an interim deployment of SFC functionality in brownfield
networks.
