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.
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.
