Method and system for automatically rerouting logical circuit data in a virtual private network
First Claim
1. A method of automatically rerouting logical circuit data in a virtual private data network, the method comprising:
- monitoring a dedicated logical circuit for status information pertinent to the dedicated logical circuit, wherein the dedicated logical circuit comprises a primary communication path for communicating data;
identifying a failure of the dedicated logical circuit based on the status information;
identifying a logical failover circuit comprising an alternate communication path for communicating the data; and
rerouting the data to the logical failover circuit without manual intervention.

Abstract
A method and system are provided for automatically rerouting logical circuit data in a virtual private network (“VPN”). A dedicated logical circuit in the VPN is monitored for status information pertinent to the dedicated logical circuit. The dedicated logical circuit includes a primary communication path for communicating data. Based on the status information, a failure is identified in the dedicated logical circuit. Once the failure in the dedicated logical circuit is determined, a logical failover circuit is then identified. The logical failover circuit includes an alternate communication path for communicating the data for the failed dedicated logical circuit. After the logical failover circuit has been identified, the data from the dedicated failed logical circuit is rerouted to the logical failover circuit without manual intervention. After the data has been rerouted the logical failover circuit, a determination may be made as to whether the failure in the dedicated logical circuit has been corrected. If it is determined that the failure in the dedicated logical circuit has been corrected, then the data from the logical failover circuit is rerouted back to the dedicated logical circuit in the VPN without manual intervention.
