Provided is a system and method for controlling overload in a telecommunications network. The network carries a traffic load that may exceed a maximum resource capacity and drive the network into an overload state. The method determines whether an overload state has occurred by comparing a current resource capacity to an overload onset threshold. If the threshold has been exceeded, the method blocks a certain percentage of traffic. An incrementally increasing percentage of traffic is blocked until the resource capacity crosses an overload abatement level. The method then incrementally decreases the percentage of blocked traffic until no traffic is blocked.
