ANALYSIS OF DATA DELAYS FOR AN INTEGRATED DATA VOICE LINK.

We study the performance of a communication link carrying data and voice traffic. The capacity of the link is assumed to be insufficient for both types of traffic during periods of peak demand, and data is subject to delays due to buffering. In our model, data is assumed to arrive at a constant fixed rate and is assured a minimum grade of service. Voice is generated by multiple sources that turn on and off randomly. The measure of voice performance is the probability that voice traffic is lost, and the distribution of data delay measures data performance. We obtain closed form expressions for these performance measures and investigate the effects of various system parameters on the performance for data and voice traffic.
