带有两个优先权M/M/s排队的通信网交换性能分析

The Performance Analysis of Communication Network Switch on the M/M/s Queue with Two Priorities

目前 ,基于不同优先权的通信网交换的研究十分活跃 文中分析了通信网中输入为泊松到达 ,带有两个优先权的M/M/s排队交换系统 通过对状态转移方程和部分状态转移方程的分析 ,得出了到达交换器的两种信元 (分组 )的稳态队长 ,并利用指数分布和泊松分布的关系 。

Currently the research on communication network switching with various priorities is one of the most active research fields. The switching system on the M/M/s queue with two priorities and poisson arrivals in communication network is analyzed in this paper. The mean queue lengths of two kinds of cells arrived to switch are obtained through the analysis of state equilibrium equations and partial state equilibrium equations. By using the relationship between exponential distribution and poisson distribution,the average queue length at the output lines is also derived.
