Technical Summary
The Path Computation Element Communication Protocol (PCEP) provides
mechanisms for Path Computation Elements (PCEs) to perform path
computations in response to Path Computation Clients (PCCs) requests.
Although PCEP explicitly makes no assumptions regarding the
information available to the PCE, it also makes no provisions for PCE
control of timing and sequence of path computations within and across
PCEP sessions. This document describes a set of extensions to PCEP
to enable stateful control of MPLS-TE and GMPLS LSPs via PCEP.
Working Group Summary
The document already has a long history. It started with squatting some codepoints,
which resulted in publishing RFC 7470, a.k.a. "RFC 7150 bis".
Some changes have been heavily argued, mainly because of some reluctance to update
existing implementations, but this version reflects a WG consensus.
Document Quality
There are several implementations, including one open source (OpenDaylight).
Have a significant number of vendors indicated their plan to implement the specification?
Yes, even more have plans.
Are there any reviewers that merit special mention as having done a thorough review,
e.g., one that resulted in important changes or a conclusion that the document had no
substantive issues?
Some updates have been triggered by a couple of operators, thanks to some
interoperability testing between several implementations.
If there was a MIB Doctor, Media Type or other expert review,
what was its course (briefly)? In the case of a Media Type
review, on what date was the request posted?
