Abstract
Abstract A method and system are provided for calculating the simultaneous service capacity for multimedia traffic under aggregate traffic conditions within a shared transmission medium, such as an ATM network. A total number of different traffic services as well as a specification of the 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. The number and size of queues utilized for receiving packetized telecommunication traffic within the network are also specified. The length and time of a busy period specified by the network operator/designer, a maximum acceptable packet loss rate and the probability that a user will access the network during the busy period are also specified. Finally, the percentage of all subscribers who subscribe to each service and the average session duration for each service are also specified. Thereafter, utilizing these parameters, the simultaneous capacity for the network can be accurately determined, whether a single central queue or multiple distributed queues are utilized.
