System for preventing server overload by adaptively modifying gap interval that is used by source to limit number of transactions transmitted by source to server

摘要

An apparatus and method for preventing overload of a network server by messages received from a source initiating network server transactions. The method and apparatus use available network traffic measurements to estimate target transaction rates and admission factors. The method includes the steps, executed by a processor, of establishing a target incoming transaction workload per measurement interval (602), estimating from measurements obtained during the measurement interval the transaction workload offered by a source (604), and reducing a rate at which new transactions are initiated by the source to match the incoming transaction workload to the target workload when the offered transaction workload exceeds a threshold (606).
