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