While the current GMPLS WSON framework can deal with many types of
wavelength switching systems there is a desire to extend this control
plane to include other common optical or hybrid electro optical
systems such as OEO switches, regenerators, and wavelength
converters. Such systems can be limited to processing only certain
types of WSON signals. In addition, if such a system can support more
than one type of WSON signal it may need to be provisioned as to the
characteristics of the signal that it will be processing.
This document provides a WSON signal definition and characterization
based on ITU-T interface and signal class standards and describes the
signal compatibility constraints of this extended set of network
elements. The signal characterization and network element
compatibility constraints enable GMPLS routing and signaling to
control these devices and PCE to compute optical light-paths subject
to signal compatibility attributes.
