Information Model for Wavelength Switched Optical Networks (WSONs) with
                         Impairments Validation
                 draft-martinelli-ccamp-wson-iv-info-03

Abstract

   This document defines an information model to support Impairment-
   Aware (IA) Routing and Wavelength Assignment (RWA) function.  This
   operation might be required in Wavelength Switched Optical Networks
   (WSON) that already support RWA and the information model defined
   here goes in addition and it is fully compatible with the already
   defined information model for impairment-free RWA process in WSON.

   This information model shall support all control plane architectural
   options defined for WSON with impairment validation.
