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.
