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