Abstract

   This document provides a model of information needed by the routing
   and wavelength assignment (RWA) process in wavelength switched
   optical networks (WSONs).  The purpose of the information described
   in this model is to facilitate constrained lightpath computation in
   WSONs. This model takes into account compatibility constraints
   between WSON signal attributes and network elements but does not
   include constraints due to optical impairments. Aspects of this
   information that may be of use to other technologies utilizing a
   GMPLS control plane are discussed.
