Abstract

A method and apparatus for addressing a congestion condition in a communication network are disclosed. For example, the method receives an alert for at least one of: a trunk or a Permanent Virtual Circuit (PVC), where the trunk or the PVC is associated with a route. The method determines whether the alert is associated with a congestion condition by determining whether a trunk utilization has exceeded a first predetermined threshold for the trunk or for the at least one trunk supporting the PVC. The method then rebuilds the route if the first predetermined threshold is exceeded for the trunk or for the at least one trunk supporting said PVC.
