摘要

本文基于流体流模型分析了网络话音复用器中有限缓冲的丢失特性.通过仿真实验

发现对于突发度较高的话音源模型

采用流体流模型可以较好地预测丢失特性的趋势

但是误差较大.而通过拟合后修正的公式可以更加精确地得出丢失率的数值解.

Abstract

In this paper

we analyze the property of loss in a packet-voice multiplexer with limited buffer based on flow-fluid model.From the simulation

we find that

in the multiplexing of such bursty voice sources

the flow-fluid model can dope out the trend of loss with a bit more gap.A more accurate solution of loss could be obtained with our fitting analysis of modified formula from flow-fluid model.
