Abstract
A method and system for assessing quality of service for multimedia traffic under aggregate traffic conditions in a shared transmission network, such as an ATM network. A total number of different traffic services as well as a maximum number of sources for each traffic service are specified by a network operator/designer. Next, for each traffic service a specification of peak rate, average idle sojourn time and an average burst sojourn time are determined, either based upon available standards or calculated based upon models of the traffic services. The total available system bandwidth is specified by a network operator/designer. Finally, the number and size of queues utilized for receiving packetized telecommunication traffic within the network are specified. The maximum packet loss ratio, average delay for a packet traversing the network and the probability that jitter (delay variations) will exceed a specified threshold are then calculated for the size and number of queues specified, permitting the quality of service within the network to be accurately and efficiently assessed.
