Abstract
This document provides Generalized Multiprotocol Label Switching
(GMPLS) Open Shortest Path First (OSPF) routing enhancements to
support signal compatibility constraints associated with Wavelength-
Switched Optical network (WSON) elements. These routing enhancements
are applicable 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 Optical-Electronic-Optical
(OEO) switches, regenerators, and wavelength converters since such
systems can be limited to processing only certain types of WSON
signals.
