Abstract 

   This document provides GMPLS OSPF routing enhancements to support 
   signal compatibility constraints associated with WSON network 
   elements. These routing enhancements are required in common optical 
   or hybrid electro-optical networks where not all of the optical 
   signals in the network are compatible with all network elements 
   participating in the network.  

   This compatibility constraint model is applicable to common optical 
   or hybrid electro optical systems such as OEO switches, 
   regenerators, and wavelength converters since such systems can be 
   limited to processing only certain types of WSON signals.
