通信系统独立队列与相关队列的分析比较

Analysis of an Independent Queue and a Correlated Queue in a Communication System

经典排队模型采用独立性假设分析网络的性能 ,忽略通信系统中的某些相关性 ,它往往会得到较为苛刻的结论。而相关性排队模型则提出 ,相关性对系统性能的影响很重要 ,而且这种相关性会对系统性能起一种平滑作用。文中对 IP网中的一个具体模型进行分析 ,用两种排队模型进行数值计算并比较 。

Classical queueing models would analyze the performance of a network with independence assumption,which leads to relatively rigorous results.The paper first presents that the correiation in a communication system is very important,which can smoothen the performance of a communication system.And then studies a material model on the basis of the former theory and compares the two queueing models with calculation,finally achieves a better model which accords to the real network.
