多媒体业务的相位逼近模型

Approximation Models of Phases for Multimedia Traffic

相位逼近模型可以精确地描述任何随机过程，本文对多媒体业务的特性进行分析，分别建立相应的相位逼近模型，计算各相位逼近模型的参数，最后给出针对ＭＭＰＰ业务模型的相位逼近模型的仿真数值结果。

Theroetically an arbitrary stochastic process can be approximated by the method of phases as exact as possible. In this paper we study the characters of multimedia traffic, establish models for them by the method of phases and work out the parameters of these models. Finally, We presente the comparison between theroetical MMPP and its approximation model. It shows that the method is accurate enough.
