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.

1. Introduction

   The documents [RFC6163, WSON-Info, WSON-Encode] explain how to
   extend the wavelength switched optical network (WSON) control plane
   to allow both multiple WSON signal types and common hybrid electro
   optical systems as well hybrid systems containing optical switching
