METHODS AND SYSTEMS FOR AUTOMATICALLY REROUTING LOGICAL CIRCUIT DATA FROM A LOGICAL CIRCUIT FAILURE TO A DEDICATED BACKUP CIRCUIT IN A DATA NETWORK
First Claim
1. A method of rerouting data, comprising:
- determining a status of a logical circuit in a data network, the status including at least one of a committed information rate or a committed burst size;
detecting a failure of the logical circuit based on determining that the at least one of the committed information rate or the committed burst size has been exceeded; and
rerouting data from the logical circuit to a logical failover circuit in the data network in response to detecting the failure of the logical circuit, wherein the logical failover circuit comprises an alternative communication path for communicating the data.

Abstract
A method and system are provided for automatically rerouting logical circuit data from a physical circuit failure in a data network. When a failure in a logical circuit is detected, a label or services name associated with the logical circuit is automatically associated with a logical circuit identifier utilized for identifying the logical circuit in the 10 data network. Once the logical circuit is associated with the logical circuit identifier, the logical circuit data may be automatically rerouted to a “failover network,” thereby minimizing lost data until the failure in the logical circuit is resolved. The logical failover circuit may be an already existing logical circuit provisioned over a dedicated backup physical circuit in the data network.
