ABSTRACT

Abstract This paper is concerned with a time division multiplexing method with two

priority classes applicable for Dynamic Transfer Mode (DTM) networks. The method is useful to better utilize the capacity of DTM channels while the requirements of delay and delay sensitive traffic sources are also satisfied. A discrete-time model is performed to analyze the queuing behavior of low priority traffic streams. The model uses the important observation that from the viewpoint of low priority messages the system behaves as a queuing system subjected to periodic server interruption. The probability generating function (pgf) of the system time of low priority messages is expressed in closed form. Tail probabilities of system content and system time are derived by applying an efficient approximation technique. Finally, we give a simple illustration for the performance evaluation.
