Abstract: Systems and methods for performing a Control Plane Triggered (CPT) Optical Protection Switching (OPS) policy are provided. A method, according to one implementation, includes performing a first route switching procedure for switching routes between an originating node and a terminating node. The first route switching procedure is configured to operate at a first priority level according to an Optical Protection Switching (OPS) policy. The method also includes performing a second route switching procedure for switching routes between the originating node and the terminating node. The second route switching procedure is configured to operate at a second priority level according to a second protection policy, wherein the second priority level is higher than the first priority level. Also, the method includes reverting back to a home path according to the first route switching procedure after one or more faults, defects, or degradations have been cleared from the home path.

Abstract: Systems and methods include, responsive to a fault affecting an optical service on an active path in an optical network operating at a frequency ?1 via an optical transceiver and having optical line protection via an optical protection switch, switching to an inactive path that now becomes the active path and finding a new route in the optical network for the inactive path that has the fault; responsive to being unable to find a route at the frequency ?1, switching the inactive path to a new route at a different frequency ?2; and implementing spectrum coordination relative to the inactive path to either determine the frequency ?1 is available on the new route or to find another new route for the inactive path where the frequency ?1 is available.
