利用话务模拟技术分析电话网动态路由策略的性能

Analysing the Performance of Dynamic Routing Schemes by Traffic Simulation

本文以动态控制选路（ＤＣＲ）和动态迂回选路（ＤＡＲ）两种动态路由策略为研究对象，采用话务模拟技术研究其应用于我国长途电话网后的网络运行情况，定量评估了动态选路所能带来的网络接通率和网络适应故障能力的提高，并对ＤＡＲ算法中继预留参数的选择进行了研究。

Traffic simulation is used to analyse the performence of two kinds of dynamic routing schemes which are called Dynamically Controlled Routing (DCR) and Dynamic Alternate Routing(DAR). The running case of our toll network adopting dynamic routing strategy is studied, the improvement of call success ratio and adaptive ability to network failure is evaluated, and the parameter of trunk reservation in DAR is selected based on experiments.
