The invention relates to a method and apparatus for measuring and recording traffic at nodes in a data transmission network. In particular the invention provides a method of accurately counting individual activities of traffic at individual nodes. The invention is carried out in hardware by using a counter or number of counters which count individual activities of traffic on a preset activity condition being sensed at a node. The invention has the advantage that accurate measurement of traffic at a node is achieved. The invention is also easy to implement in hardware and overcomes the problems inherent in present software solutions.

Measure and recording of traffic parameters in data transmission networks

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 approximation 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.
