Method and system for utilizing a logical failover circuit for rerouting data between data networks
摘要:
A method and system are provided for utilizing a logical failover circuit for rerouting data from a failed network circuit in a first data network to a second data network. The network circuit in the first data network includes a logical circuit for communicating data. When a failure in the network circuit in the first data network is detected, a network failover circuit is selected in the second data network. The network failover circuit in the second data network includes a logical failover circuit for communicating data. The data in the failed logical circuit in the first data network is rerouted over the logical failover circuit in the second data network until the failure in the network circuit in the first data network is resolved. After the failed network circuit in the first data network has been restored, the data is rerouted over the restored logical circuit. The first data network may be contained within an Inter-Exchange Carrier and the second data network may be contained within a Local Exchange Carrier.
