摘要 基于现实网络业务流呈现自相似的特点,利用矩阵几何和剩余累积分布函数拟合的方法研究了Pareto到达时间间隔和负指数服务时间,以及多服务台和有限缓存空间下的网络排队系统性能,并获得了P(areto)/M/c/K+c队列平均排队队长和缓存溢出概率的近似结果,详细的仿真结果验证了这种方法具有较高的精确性。 As the inter-arrival time of traffics exhibit self-similar, queuing performance of the network with Pareto distribution inter-arrival time and negative exponential distribution service time distribution are investigated via the fitting technique of complementary cumulative distribution function and the matrix geometric method. The average queue length and buffer overflow probability of P（areto）/M/c/K ＋ c are derived. Simulation validate the theory results.
