Methods and systems for automatically rerouting logical circuit data
First Claim
1. A method of automatically rerouting logical circuit data, the method comprising:
- identifying a failure of a dedicated logical circuit in a packet-based network, the dedicated logical circuit having a first logical circuit identifier assigned prior to identifying the failure, and the dedicated logical circuit connecting a host device to a remote device to communicate data that originates and terminates only at the host device and the remote device;
selecting a logical failover circuit comprising an alternate communication path for communicating the data;
when the first logical circuit identifier of the dedicated logical circuit does not match a second logical circuit identifier of the logical failover circuit;
renaming the second logical circuit identifier of the logical failover circuit to identify the logical failover circuit using the first logical circuit identifier of the dedicated logical circuit when the logical failover circuit is a dedicated logical failover circuit used to communicate only when the dedicated logical circuit fails, andrenaming the dedicated logical circuit to identify the dedicated logical circuit using the second logical circuit identifier of the logical failover circuit when the logical failover circuit is used to communicate regardless of the failure of the dedicated logical circuit; and
rerouting the data to the logical failover circuit without manual intervention.

Abstract
Methods and systems are provided to automatically reroute logical circuit data. In accordance with an example method, a failure of a dedicated logical circuit in a packet-based network is identified. The dedicated logical circuit has a first logical circuit identifier assigned prior to identifying the failure. The dedicated logical circuit connects a host device to a remote device to communicate data that originates and terminates only at the host device and the remote device. A logical failover circuit comprising an alternate communication path for communicating the data is selected. When the first logical circuit identifier of the dedicated logical circuit does not match a second logical circuit identifier of the logical failover circuit, the second logical circuit identifier is renamed to match the first logical circuit identifier. The data is rerouted to the logical failover circuit without manual intervention.
