A MEASUREMENT-BASED ADMISSION CONTROL ALGORITHM FOR INTEGRATED SERVICE PACKET NETWORKS

Many designs for integrated services networks offer a bounded delay pa cket delivery service to support real-time applications, To provide ho unded delay service, networks must use admission control to regulate t heir load, Previous work on admission control mainly focused on algori thms that compute the worst case theoretical queueing delay to guarant ee an absolute delay bound for all packets, in this paper, we describe a measurement-based admission control algorithm (ACA) for predictive service, which allows occasional delay violations. We have tested our algorithm through simulations on a wide variety of network topologies and driven with various source models, including some that exhibit lon g-range dependence, both in themselves and in their aggregation, Our s imulation results suggest that measurement-based approach combined wit h the relaxed service commitment of predictive service enables us to a chieve a high level of network utilization while still reliably meetin g delay bound.
