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.
