Abstract

We propose a new space priority mechanism, and analyze its performance in a single CBR server. The arrival process is derived from the superposition of two types of traffic, each in turn results from the superposition of homogeneous on-off sources that can be approximated by means of a two-state Markov modulated Poisson process (MMPP). The buffer mechanism enables the ATM layer to adapt the quality of the cell transfer to the QoS requirements and to improve the utilization of network resources. This is achieved by "selective-delaying and pushing-in" (SDPI) cells according to the class they belong to. The scheme is applicable to schedule delay-tolerant non-real time traffic and delay-sensitive real time traffic. Analytical expressions for various performance parameters and numerical results are obtained. Simulation results in terms of the cell loss probability (CLP) conform with our numerical analysis.
