Abstract
A novel system for regulating traffic in a communications network by adaptive rate control is disclosed. In a network system having time sensitive messages that require processing within certain time limits, the load queued at network elements with at least one message processor is dynamically controlled to prevent the message processor from becoming overloaded and thereby causing queued messages from timing out without being processed. A threshold value based on a processing parameter such as when a message times out is compared to an average queuing delay and the controlled load is varied in response thereto. Each message processor determines one or more processing statistics from which a controlled load rate applied to at least one source controller is determined. By dynamically varying the controlled load and not merely relying upon a fixed buffer to control message queues, the novel system disclosed herein can respond to changes in the offered load and/or service rate without overloading the message processor.
