Vg. Kulkarni et N. Gautam, ADMISSION CONTROL OF MULTICLASS TRAFFIC WITH SERVICE PRIORITIES IN HIGH-SPEED NETWORKS, Queuing systems, 27(1-2), 1997, pp. 79-97
We consider a fluid model of a system that handles multiple classes of
traffic. The delay and cell-loss requirements of the different classe
s of traffic are generally widely different and are achieved by assign
ing different buffers for different classes, and serving them in a str
ict priority order. We use results from the effective bandwidth of the
output processes (see Chang and Thomas (1995)) to derive simple and a
symptotically exact call-admission policies for such a system to guara
ntee the cell-loss requirements for the different classes assuming tha
t each source produces a single class traffic. We compare the admissio
n-control policies developed here with the approximate policy studied
by Elwalid and Mitra (1995) for the case of two-class traffic.
