Abstract:
SFC (Service Function Chaining) is used to manipulate service
functions with easy creation, updating and deletion. A service
function chain goes through a list of ordered service function
instances. One assumption of this document is that legacy service
function instances can participate in the service chain. They are
not aware of the SFC header, nor interpret it. This document
provides a mechanism between a Service Forwarding Entity (SFE) and a
Service Function Instance (SFI), to identify the SFC header
associated with a packet that is returned from an SFI, without SFC
header being explicitly carried in the wired protocol between SFE and
SFI.
