Abstract

We consider a fluid model of a system that handles real-time and data traffic. The delay and cell-loss requirements of these two types of traffic are generally widely different and are achieved by assigning different-sized buffers for the two classes, and serving real-time traffic ahead of data traffic. We use results from the effective bandwidth of the output processes (see Chang and Thomas [1] ) to derive simple and asymptotically exact call-admission policies for such a system to guarantee the cell-loss requirements for the two classes. We compare the admission-control policy developed here with the approximate policy studied by Elwalid and Mitra [9]. This work was partially supported by NSF Grant No. NCR-9406823 i 1 Introduction The concept of effective bandwidth and its use in the admission control for the statistical multiplexing of bursty sources is now well-documented and accepted.
