分组语音流的流体流动模型

Fluid Source Modeling of Packet Voice

语音信息在基于 ATM信元传输的宽带综合业务网中的传输是极大区别于以往的电路交换技术的 ,也是不同于主要用于传输数据的分组交换网的。介绍了一种用于模拟 ATM网中的分组复用语音流传输的模型 :流体流动模型。并用这种模型对语音传输中的信元丢失率进行了计算和研究 。

Voice traffic in the B-ISDN based on ATM cell transmission differs considerably from the case of the circuit-switched telephone networks,and the recent packet-switched netwoks designed to handle data..In this paper,a model for packet voice multiplexing system of ATM was introduced,which is called a fluid flow model.Here this model is used to calculate and discuss the cell loss probability for voice traffic.Conclusions are drawn at last.
