A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Common Control and Measurement Plane Working Group of the IETF.

   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.
