Abstract:
A Service Function Chain (SFC) defines a set of abstract Service
Functions (SF) and ordering constraints that must be applied to
packets and/or frames selected as a result of classification. One
assumption of this document is that legacy service functions can
participate in service function chains without having support for the
SFC header, or even being aware of it. This document provides a
mechanism between an SFC proxy and an SFC-unaware service function
(herein termed "legacy SF"), to identify the SFC header associated
with a packet that is returned from a legacy SF, without an SFC
header being explicitly carried in the wired protocol between SFC
proxy and legacy SF.
