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 Path Computation Element (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; or
measurement of, or assessment and qualification of, a route;
rather, it describes the architectural and information components for
protocol solutions. This document is not an Internet Standards Track
specification; it is published for informational purposes.
This document is a product of the Common Control and Measurement Plane Working Group of the IETF.
