Title : PCEP Requirements for WSON Routing and Wavelength Assignment
Author(s) : Y. Lee, et al.

This memo provides application-specific requirements for the Path
Computation Element communication Protocol (PCEP) for the support of
Wavelength Switched Optical Networks (WSON). Lightpath 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 light path
computation. Requirements for Optical impairments will be addressed
in a separate document.
