The Path Computation Element (PCE) Working Group of the IETF is pleased to
inform you of the publication of two new RFCs that may be of interest to your
members in particular with reference to G.7715.2. describes generic requirements for a
communication protocols operating between PCCs and PCEs, and between
cooperating PCEs. Additional specific requirements for particular deployment
scenarios (such as inter-area, inter-AS,  multi-layer, etc.) are covered in
separate Internet-Drafts. sets out the requirements for discovery of
PCEs and their capabilities.

In addition, the working group is very active in specifying
application-specific uses of PCE, a policy-related framework, and protocols,
protocol extensions, monitroing, and management in support of PCE.

We would welcome input from all ITU-T participants. Ideas, opinions, and
contributions should be sent to the PCE email list. Details of how to join the
mailing list can be found at the PCE charter page
( which also provides
pointers to all of the current PCE Internet-Drafts.

In the light of G.7715.2, it may be that your members are interested in seeing
how the existing PCE protocol work can be applied to meet your requirements.
