Method and system for prioritized rerouting of logical circuit data in a data network
First Claim
1. A method to reroute logical circuit data in a data network, the method comprising:
- identifying a failed logical circuit established for a customer in the data network;
determining a first quality of service parameter for communication of data associated with the customer in the failed logical circuit;
identifying a logical failover circuit comprising an alternate communication path for communicating the data associated with the customer;
determining a second quality of service parameter for communication of data in the logical failover circuit;
when the first quality of service parameter for the failed logical circuit is equal to or less than the second quality of service parameter for the logical failover circuit, rerouting the data associated with the customer to the logical failover circuit without requiring authorization from the customer to communicate the data at the second quality of service parameter; and
when the second quality of service parameter for the logical failover circuit is a lower level of quality than the first quality of service parameter for the failed logical circuit;
prompting the customer for an authorization to communicate the data associated with the customer via the logical failover circuit at the second quality of service parameter;
when the authorization is received, rerouting the data from the failed logical circuit to the logical failover circuit; and
when the authorization is denied, not rerouting the data to the logical failover circuit.

Abstract
A method and system are provided for prioritized rerouting of logical circuit data in a data network. A logical circuit failure is identified in the data network. Following the identification of the logical circuit failure, a quality of service parameter for the communication of data in the failed logical circuit is determined. The quality of service parameter may include a traffic descriptor indicating the quality of the data communicated in the logical circuit. Then, a logical failover circuit comprising an alternate communication path for communicating the data in the failed logical circuit is identified. Next, a quality of service parameter for the communication of data in the logical failover circuit is determined. If the quality of service parameter for the failed logical circuit is equal to the quality of service parameter for the logical failover circuit, then the data from the failed logical circuit is rerouted to the logical failover circuit. In this manner, the quality of the data in the logical failover circuit is communicated at the same level of service provisioned for the failed logical circuit.
