Abstract:

As all the traffics whose arrival time interval submits to Pareto distribution have the self-similarity,the queuing behavior of the network system with Pareto distribution inter,·arrival time and negative exponential distribu-tion service time distribution is investigated via the fitting technique of complementary cumulative distribution function and the matrix geometric method.The average queue length and buffer overflow probability of Pareto/M/1/K qu eue are then approxima tely derived.Simulated results are finally presented to verify the accuracy of the proposed method/

Key words: trafic input, self-similarity, queuing performance, Pareto distribution, hyperexponential distribution, phase-type distribution
