Technical Summary

Although [RFC4655] defines the PCE architecture and framework for
both MPLS and GMPLS networks, most preexisting PCEP RFCs [RFC5440],
[RFC5521], [RFC5541], [RFC5520] are focused on MPLS networks, and do
not cover the wide range of GMPLS networks.  This document
complements these RFCs by addressing the extensions required for
GMPLS applications and routing requests, for example for OTN and WSON

Working Group Summary

Though uncontroversial, this work had a long life. Some other work with strong market demand (stateful PCE, mainly) came along and this document got stuck for a while in the WG's and chairs' backlog.

Document Quality

There are several implementations, commercial and open source, of the base protocol. The extensions from this document were implemented (at least partially) by some work from the research community. Open source (OpenDaylight) is in the pipe.

At lest two vendors worked on the document. The implementation by a few optical vendors is mentioned by some (available) research publications.
