Traffic characterization for integrated services

Abstract

A traffic model in which the interruption traffic is a correlated process is introduced. In this model the effect of correlation is culminated in a parameter that is the sum of all the imbalances of the autocorrelation function of the interruption process. Based on this model, the queueing analysis of integrated services on a packet switched TDM system is developed. It is shown that the presence of correlation increases the mean queue length. An adaptive flow control scheme that successively adjusts the short-bursty traffic arrival rate at each TDM node to reduce the correlation effect on the queue length build-up is proposed.<>
