Abstract

This paper presents the matrix analytic analysis of a dual non-pre-emptive priority system with constant service times. For each priority class, arrivals occur for two separate queues with infinite buffers and are modelled as two independent Markov-modulated Poisson processes. The queue length densities and queuing delays of this system are computed using the above approach for some typical examples. They are found to be in agreement with the results obtained through simulation. Approximate models for this system and their range of validity are also considered. The applications of the results to ATM networks are discussed.
