Method and system for automatically rerouting data from an overbalanced logical circuit in a data network
First Claim
1. A method of automatically rerouting data from an overbalanced logical circuit in a data network, the method comprising:
- receiving status information for a logical circuit in the data network, the logical circuit comprising a communication path for communicating data;
determining an overbalanced condition in the logical circuit based on the status information, wherein the overbalanced condition is indicative of congestion in the logical circuit;
identifying a logical failover circuit comprising an alternate communication path for communicating the data in the overbalanced logical circuit; and
rerouting the data to the logical failover circuit without manual intervention.

Abstract
A method and system are provided for automatically rerouting data from an overbalanced logical circuit in a data network. Status information is received for a logical circuit communicating data in the data network. The status information may include a forward explicit congestion notification (“FECN”) and a backward explicit congestion notification (“BECN”) indicating an overbalanced condition in the logical circuit. An overbalanced condition is indicative of network congestion in the logical circuit. A logical failover circuit including an alternate communication path for communicating the data in the overbalanced logical circuit is then identified. The data in the overbalanced logical circuit is rerouted to the logical failover circuit without manual intervention. After rerouting the data to the logical failover circuit, a determination is made as to whether the overbalanced condition in the logical circuit has been cleared. If it is determined that the overbalanced condition in the logical circuit has been cleared, then the data from the logical failover circuit is rerouted to the logical circuit in the data network without manual intervention.
