SDH自愈环生存性定量分析

Approaches to Quantitative Analysis of Survivability for SDH Self-Healing Ring Network

本文首先提出了网络生存性指标的概念 ,并对基于SDH自愈环拓扑结构的网络在灾害条件下的网络生存性进行了定量研究 .文中分析了不同的业务分布条件对网络生存性指标的影响 ,以及灾害强度和网络生存性的关系 .

The definition of network survivability is presented.Then,the network survivability of SDH self-healing ring network under links failure is quantitatively analyzed.The relation between traffic distribution and network survivability and the effect of disaster on network survivability are studied.
