Hi,
We have published a revision (v.4) entitled, "PCEP Requirement for WSON
Routing and Wavelength Assignment"
Two major changes from v.3 are:
- We separated requirements from solutions
- We combined requirements for non-impairment RWA with
Impairment-aware RWA.
We'd appreciate your comments and discussion in the mailing list. Thanks.
Young

Title : PCEP Requirements for WSON Routing and Wavelength
Assignment

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. Additionally, optical impairments may add further
constraints on the paths available for use.
