Abstract

In this paper, we propose an analytical expression for estimating byte loss probability at a single server queue with multifractal traffic arrivals. The obtained expression is robust, stable and accurate in comparison with some existing methods in literature. Next we evaluate the potentiality of applying the proposed method in connection admission control by comparing with some other widely used admission control approaches. Finally we present a dynamic bandwidth allocation mechanism based on our multifractal based loss probability estimation method. Extensive experimental tests validate the efficiency and accuracy of the proposed loss probability estimation approach, its superior performance for admission control and link resource allocation applications with respect to some well-known approaches suggested in the literature.
