Title : PCEP Requirements for WSON Routing and Wavelength Assignment
Author(s) : G. Bernstein
Filename : draft-lee-pce-wson-routing-wavelength-05.txt
Pages : 11
Date : 2009-06-29
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 related to optical impairments will be
addressed in a separate document.
