用于长距离相关互联网业务的马尔可夫调制开/关过程

Markov-modulated on/off processes for long-range dependent internet traffic

Richard G. Clegg

摘要:

本文的目的是使用一个非常简单的排队模型来比较一些模型,从文献中已被用来复制互联网流量的统计性质,特别是这种流量的长期依赖性。这四个模型都具有离散时间马尔可夫调制过程的形式(为了比较的目的,引入了另外两个模型)。虽然人们经常说,长期依赖性对排队性能有着至关重要的影响,但这里使用的模型似乎并不能很好地复制真实互联网流量的排队性能。特别是,他们无法复制平均队列长度(因此平均延迟)和队列长度超过给定水平的概率。

英文摘要:

The aim of this paper is to use a very simple queuing model to compare a number of models from the literature which have been used to replicate the statistical nature of internet traffic and, in particular, the long-range dependence of this traffic. The four models all have the form of discrete time Markov-modulated processes (two other models are introduced for comparison purposes). While it is often stated that long-range dependence has a critical effect on queuing performance, it appears that the models used here do not well replicated the queuing performance of real internet traffic. In particular, they fail to replicate the mean queue length (and hence the mean delay) and the probability of the queue length exceeding a given level.
