Methods and systems for automatically rerouting logical circuit data in a data network
A disclosed example method involves identifying a logical failover circuit comprising an alternate communication path in a failover network that is separate from a logical circuit comprising variable communication paths in at least one of a first logical telecommunications network or a second logical telecommunications network and a fixed communication path between the first and second logical telecommunications networks. The failed logical connection is between the first and second logical telecommunications networks. The failover network is 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. The logical circuit identifier of the logical circuit is renamed to the second logical circuit identifier of the logical failover circuit when a logical connection in the logical circuit has failed. The data is rerouted from the logical circuit to the logical failover circuit without manual intervention.
