ANALYSIS OF AN ATM MULTIPLEXER WITH CORRELATED REAL-TIME AND INDEPENDENT NON-REAL-TIME TRAFFIC

This paper presents an alternative traffic model for an ATM multiplexe r providing video, voice, image, and data services. The traffic model classifies the input traffic into two types: real-time and non-real-ti me. The input process for real-time traffic is periodic and correlated , while that for non-real-time traffic is batch Poisson and independen t. This multiplexer is assumed to be a priority queueing system with s ynchronous servers operating on time-frame basis and with separate fin ite buffers for each type of traffic. State probabilities and performa nce measures are successfully obtained using a Markov analysis techniq ue and an application of the residue theorem in complex variable. The results can be applied in the design of an ATM multiplexer.
