摘要
网络生存性是高速通信网络的重要性能评估指标,但是目前尚没有统一的定量分析方法。该文提出同步数字体制(SDH)接入网网络生存性的定量分析方法,得到网络生存性与破坏强度之间的定量关系,为SDH接入网网络生存性的预测和评估提供了理论依据。另外,对环型和链型SDH接入网的生存性进行比较分析,从理论上证明SDH接入网使用环型拓扑比使用链型拓扑具有更好的生存性,该研究结果可为SDH接入网的网络拓扑设计提供参考。
Network survivability is an important factor in highspeed telecom networks, but there are no standard methods to quantitatively analyze survivability. A method was developed to quantitatively analyze the survivability of synchronous digital hierarchy (SDH) access networks which relates the network survivability and the extent of the network damage. The result is useful for forecasting and evaluating the survivability of SDH access networks. Comparison of the survivability of the SDH ring and the SDH line shows that the survivability of the SDH ring is better than that of the SDH line network in principle. This conclusion will influence the type of topology used for designing SDH access networks.
