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. Specifically, this document discusses key computing
constraints, scenarios and architectural processes: Routing,
Wavelength Assignment, and Impairment Validation. 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.
