Channels that Cooperatively Service a Data Stream and Voice Messages

This paper presents an analysis of the performance of a special type of voice-data queueing system. The system consists of an integrated circuit-and packet-switched multiplexer resembling that found in the SENET network. A fluid-flow approximation for the data component is introduced to ease study of the voice loss rate and data packet waiting times. In this paper it is shown that very long data queues are possible, with the mean data queue length being proportional to the ratio of the holding time for voice to the holding time for data. The equilibrium distribution is determined, and aspects of the transient behavior are characterized. The question of how much bandwidth to reserve for exclusive use of data and how much to share between voice and data is addressed.
