Hi, folks:
We have updated document to get alignment with draft-ietf-teas-pce-central-control-00.
1.Distinguish PCEP based SFP instantiating signaling from metadata exchanging in data plane to establish SFP in Section 7.
2.Distinguish PCE role for computing path and instantiate service path from controller role for defining policy to install SFC-related state in section 5
Your comments, suggestions and input are welcome

Regards!
-Qin

Abstract:
   This document provides an overview of the usage of Path Computation
   Element (PCE) to dynamically structure service function chains.
   Service Function Chaining (SFC) is a technique that is meant to
   facilitate the dynamic enforcement of differentiated traffic
   forwarding policies within a domain.  Service function chains are
   composed of an ordered set of elementary Service Functions (such as
   firewalls, load balancers) that need to be invoked according to the
   design of a given service.  Corresponding traffic is thus forwarded
   along a Service Function Path (SFP) that can be computed by means of
   PCE.

   This document specifies extensions to the Path Computation Element
   Protocol (PCEP) that allow a stateful PCE to compute and instantiate
   Service Function Paths.
