Title : A Framework for the Control of Wavelength Switched Optical Networks (WSON) with Impairments

As an optical signal progresses along its path it may be altered by
the various physical processes in the optical fibers and devices it
encounters. When such alterations result in signal degradation, these
processes are usually referred to as "impairments". These physical
characteristics may be important constraints to consider when using a
GMPLS control plane to support path setup and maintenance in
wavelength switched optical networks.
This document provides a framework for applying GMPLS protocols and
the PCE architecture to support Impairment Aware Routing and
Wavelength Assignment (IA-RWA) in wavelength switched optical
networks. This document does not define optical data plane aspects;
impairment parameters, measurement of, or assessment and
qualification of a route, but rather it describes the architectural
and information components for protocol solutions.
