Abstract
In this article we analyze the performance of discrete-time multiserver ATM buffers with batch arrivals, geometric service time and priority scheduling. Such systems can be applied to the detailed performance evaluation of ATM multiplexers and ATM switching elements with dedicated buffer output queuing arrangements. Packets
belong to two classes, class-1 packets represents real time traffics which is delay sensitive but loss insensitive, and class-2 packets represents non real time traffics which is delay insensitive but loss sensitive. Higher service priority is given to real time traffics (e.g. audio and video) to respond to the delay sensitivity in the presence of multiple servers in the system. Expressions for the probability generating functions of the main performance measures of the system and expected values of these expressions are evaluated.
