ABSTRACT:
A method, system and computer program product for managing bursts of traffic. A counter, referred to herein as a “frequency counter,” is incremented during those time intervals an overload condition is detected and is decremented during those time intervals an overload condition is not detected. An overload condition may refer to when the number of out-of-dialog messages exceeds a threshold value corresponding to the maximum number of out-of-dialog messages that should be accepted and forwarded to an associated session server. If the count of the frequency counter exceeds some pre-configured value, then traffic that exceeds the threshold for the overload condition is stopped from being sent to the associated session server. Otherwise, traffic that exceeds the threshold for the overload condition is permitted to be sent to the associated session server. By managing bursts of traffic in such a manner, the effective utilization of session servers is improved.
