Technical Summary

This document provides the Path Computation Element communication Protocol
(PCEP) extensions for the support of Routing and Wavelength Assignment (RWA)
in Wavelength Switched Optical Networks (WSON).  Path provisioning in WSONs
requires a routing and wavelength assignment (RWA) process.  From a path
computation perspective, wavelength assignment is the process of determining
which wavelength can be used on each hop of a path and forms an additional
routing constraint to optical path computation.

Working Group Summary

The document is supported by the WG and no particular issue
was raised during the WG last call.

Document Quality

The protocol is widely implemented but the shepherd is not aware of any
commercial implementation of the extensions defined in this document. The
document is signed by authors from different vendors, operators and research
centers showing interest in these extensions.
