摘要： 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.

摘要： Systems and methods for utilizing backup paths to restore service in a network are provided. A method, according to one implementation, includes obtaining a route list as defined by a user, the route list including a plurality of explicitly-configured backup routes for restoring service between a source node and a destination node in a network when a working route is unavailable. The method also includes receiving input designating one or more of the explicitly-configured backup routes as one or more last-resort routes. In response to determining that the working route is unavailable and that the plurality of explicitly-configured backup routes, excluding the one or more last-resort routes, are unavailable, the method includes automatically computing one or more implicitly-computed backup routes. For restoring service between the source node and destination node, the method also includes utilizing one of the one or more implicitly-computed backup routes before utilizing one of the one or more last-resort routes.

摘要： Aspects of the subject disclosure may include, for example, a node in a fiber optic network, the node comprising a processing system comprising a processor and executable instructions that, when executed by the processing system, facilitate performance of operations, including receiving an automatic or manual trigger; checking nodes in a current working route for a failure responsive to receiving the automatic or manual trigger; raising an alarm responsive to detecting the failure; and performing operations associated with the automatic or manual trigger responsive to not detecting the failure. Other embodiments are disclosed.

摘要： Systems and methods for managing a list or restoration paths are provided. A method, according to one implementation, includes obtaining a list of restoration paths used for restoring transmission in a network when a home path between an originating node and a termination node is unavailable. The restoration paths are listed in a specific order based on ongoing transmission costs, where the ongoing transmission cost for each restoration path is based on characteristics associated with transmitting signals along the respective restoration path. The method also includes the step of reordering the restoration paths in the list based on restoration costs and the ongoing transmission costs. The restoration cost for each restoration path is based on a procedure for switching from the home path to the respective restoration path.
