Patent ID: 8254260

Claim:
A method for addressing a congestion condition in a communication network, comprising: receiving an alert for a trunk associated with a route; determining whether the alert is associated with a trunk failure alarm; determining whether the alert is associated with an asynchronous transfer mode network trouble or a frame relay network trouble if the alert is associated with the trunk failure alarm; determining via a processor whether the alert is associated with the congestion condition by determining whether a trunk utilization has exceeded a first predetermined threshold for the trunk, wherein the trunk utilization is derived from a measurement of a trunk delay for variable bit rate traffic, wherein the determining whether the alert is associated with the congestion condition further comprises determining whether a number of switches that is traversed by a packet on the route is in excess of a second pre-determined threshold; and rebuilding the route if the first predetermined threshold is exceeded for the trunk, wherein the rebuilding the route comprises providing additional resources to the route.
