摘要

提出了一种VoIP网络丢包上限估计方法。我们分析了用于经典电信网络维度划分的简单Erlang B模型及其在现代融合IP网络中的可能适用性。我们提出了一种基于所使用的编解码器和网络链路的特性来计算原始Erlang B模型的适当输入变量的方法。最后将模型结果与NS2软件的仿真结果进行了验证。

Application of Erlang B model in modern VoIP networks

The paper proposes a method for upper bound estimation of packet loss in VoIP networks. We analyze simple Erlang B model that is used for classic telecommunication networks dimensioning and its possible applicability to modern convergent IP networks. We propose a method to calculate proper input variables for the original Erlang B model based on characteristics of both codec and network link in use. Finally we verify the model results against simulation results obtained from NS2 software.
