This memo provides application-specific requirements for the Path
Computation Element Communication Protocol (PCEP) for the support of
Wavelength Switched Optical Networks (WSONs).  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 PCEP extensions in support of
optical impairments will be addressed in a separate document.

This document is a product of the Path Computation Element Working Group of the IETF.
