This document specifies the Path Computation Element Communication
Protocol (PCEP) for communications between a Path Computation Client
(PCC) and a Path Computation Element (PCE), or between two PCEs.
Such interactions include path computation requests and path
computation replies as well as notifications of specific states
related to the use of a PCE in the context of Multiprotocol Label
Switching (MPLS) and Generalized (GMPLS) Traffic Engineering. PCEP
is designed to be flexible and extensible so as to easily allow for
the addition of further messages and objects, should further
requirements be expressed in the future.
Working Group Summary
No controversy reported (see PROTO writeup by Adrian Farrel, that
I have included below). This protocol is central to the work of
the PCE working group and it therefore has been very carefully
reviewed and enjoys strong consensus in the working group.
There are a substantial number of implementations (around 10 were
recorded in an informal survey). Some of these are experimental
implementations in service provider labs, while some are academic
projects. Other implementations are for hardware and software
products and are commercially available. Private interoperability
testing has been conducted between at least four of these
implementations, and the spec updated accordingly. The document has
been extensively reviewed.

RFC Editor Note
The reference to [RFC2385] should be moved from informative
references (section 13.2) to normative references (section 13.1).
