In this paper we consider the end to end delay through a series of queues in which the service time is "xed and equal to the transmission time of constant length data packets at constant bitrate, for example real time delay sensitive tra$c in IP or ATM networks. In these cases, algorithms are required either for on-line admission control or for planning and(More)
New services are emerging rapidly within the world of telecommunications. Charging strategies that were appropriate for individual transfer capabilities are no longer appropriate for an integrated broadband communications network. There is currently a range of technologies (such as cable television, telephony and narrow band ISDN) for the different services(More)
Two approaches to Connection Admission Control (CAC) in ATM networks are presented and their relative performances are assessed. The two CAC methods are, respectively, the enhanced convolution approach (ECA), an optimised algorithm based on the deterministic convolution method and the Fuzzy CAC (FCAC) approach, a heuristic method based on a combination of(More)
