The documents [RFC6163], [RFC7446], and [RFC7581] explain how to extend the Wavelength Switched Optical Network (WSON) control plane to support both multiple WSON signal types and common hybrid electro- optical systems as well hybrid systems containing optical switching and electro-optical resources. In WSON, not all the optical signals in the network are compatible with all network elements participating in the network. Therefore, signal compatibility is an important constraint in path computation in a WSON.

   GMPLS OSPF Enhancement for Signal and Network Element Compatibility                 for Wavelength Switched Optical Networks


   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 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.
