Comparison of admission control schemes in ATM networks

Abstract

Asynchronous transfer mode (ATM) offers an efficient means of carrying a wide spectrum of BISDN traffic provided that network congestion is prevented. Unfortunately, efficient congestion control is difficult to achieve in integrated broadband networks, owing to the wide range of traffic characteristics and quality of service (QOS) requirements. We have implemented a network simulator that allows us to evaluate many proposed admission control schemes using many different traffic models. We present the results of several simulation studies, including one study of the performance of the admission control schemes in the presence of traffic sources that exhibit long‐term dependence.

Call admission control for wireless personal communications

“…During the call admission phase, the decision process of CAC is repeated over all the hops to ensure that sufficient resources are available to support the entire new connection. A significant amount of work on CAC has been done for the wireline domain alone [13,16,27,28,34,36,39,40,47,64,78,80], for the wireless domain alone [17,53,67], and for both [2,3,19,21,49,65,66,85]. The works on CAC for connection oriented wireline networks (such as ATM networks) are more matured and there are usually less challenges involved.…”
