Abstract:
A Service Function Chain (SFC) defines a set of abstract service
functions 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 function can participate in
the service function chain, but they are not aware of the SFC header,
nor interpret it. This document provides a mechanism between an SFC
proxy and an SFC-unaware Service Function (i.e. legacy SF), to
identify the SFC header associated with a packet that is returned
from a legacy SF, without SFC header being explicitly carried in the
wired protocol between SFC Proxy and legacy SF.
