摘　　要：ＡＴＭ通信网中需要传送多种业务．其中有一类是具有连续比特流的业务．这种业务的发送信元到达时间是周期性的．本文分析了一种周期性信元流通过ＡＴＭ复用器的排队模型．得出信元流排队时延的概率分布、时延抖动的自相关函数和功率谱．In ATM (Asynchronous Transfer Mode) communication networks,various kinds of traffic will be transferred. Among them,a kind of traffic is composed of continuous bit-stream. The arriving time of its transferrence cells is periodic. In this paper,a queueing model for transport of periodic cell stream through an ATM multiplexer is analyzed. The probability distribution of the queueing delay,the autocorrelation and power spectrum of the cell delay jitter are obtained.
