A fluid approximation model of an integrated packet voice and data multiplexer

Abstract

A fluid approximation to an integrated packet voice and data multiplexer where the transmission of voice packets has preemptive priority over data packets is derived. Performance measures such as the average delay for both voice and data packets are given and a comparison of the average delay for data packets as a function of the data packet arrival rate is made between the analytical results and simulation results. A voice-rate flow control procedure is incorporated in the model and its effect on average voice and data packet delays is computed.<>
