IMPROVEMENTS IN AND RELATING TO TRAFFIC CONTROL IN DATA NETWORKS

摘要

A data network in which at least one switch is provided with the facility for estimating current network demands using a polygonal approximation to scaled cumulant generating function. The approximaton is iteratively refined in accordance with sampled data passing through the switch. The switch estimates the demand associated with a new data processing request as it is received by the switch and decides whether to accept the request based on available resources.
