Evaluation of the traffic coefficient in priority queueing systems

Authors: Mişcoi Gheorghe, A. Iu. Bejan, O. Benderschi
Keywords: Priority queues, switchover times, traffic coefficient.


Methodology and algorithms of evaluation of the traffic coefficient in priority queueing systems with zero and nonzero switchover times are presented. In the case of zero switchover times the calculation of the traffic coefficient is straightforward. In contrast, it relies heavily on the efficient numerical evaluation of the busy period's Laplace-Stieltjes transform in the case when switchover times are not all degenerate zero. Examples for both cases are provided.
