PERFORMANCE ANALYSIS OF DELAY-LOSS PRIORITY MECHANISM USING MARKOV MODULATED ARRIVAL STREAM

The authors propose a new mechanism to handle delay and loss requireme nts of ATM traffic simultaneously. It is designed to satisfy the diffe rent levels of cell-loss performance for two classes of heterogeneous nonreal-time ATM traffics as well as the delay and loss requirements o f real-time traffics simultaneously. The cell arrivals of input stream s are modelled by MMPP. Both a real-time buffer and a nonreal-time buf fer are served by a common server. The buffer occupancies of each traf fic are controlled by the partial buffer sharing scheme. The steady-st ate probabilities of queue-length distributions are obtained using the stochastic integral approach.
