Information Model for Wavelength Switched Optical Networks (WSONs) with
                         Impairments Validation
                 draft-martinelli-ccamp-wson-iv-info-05

Abstract

   This document defines an information model to support Impairment-
   Aware (IA) Routing and Wavelength Assignment (RWA) functionality.
   This information model extends the information model for impairment-
   free RWA process in WSON to facilitate computation of paths where
   optical impairment constraints need to considered.
