Abstract:
1. A method of automatically rerouting logical circuit data in a data network, the method comprising: determining, via a network management system, a failure of a logical connection in a logical circuit in the data network, the logical circuit identified by a logical circuit identifier in the data network, the logical circuit comprising variable communication paths in at least one of a local access and transport area or an inter-exchange carrier and a fixed communication path between the local access and transport area and the inter-exchange carrier, and the failed logical connection being between the local access and transport area and the inter-exchange carrier; identifying, via the network management system, a logical failover circuit comprising an alternate communication path to communicate the data, the logical failover circuit located in a failover network that is separate from the logical circuit, the failover network being reserved to provide failover circuits to communicate data rerouted from failed logical circuits, and the logical failover circuit identified by a second logical circuit identifier in the data network; renaming the logical circuit identifier of the logical circuit to the second logical circuit identifier of the logical failover circuit; and rerouting the data to the logical failover circuit without manual intervention.
