摘　　要：本文推导出了ＳＤＨ／ＡＴＭ双向自愈环在链路失效、节点失效及链路节点混合失效三种模型情况下的网络生存性函数，从导出的网络生存性函数可以方便地求出生存率的均值、最坏生存率、ｒ百分比生存率及零生存率等单个生存性测度．同时对导出的生存性函数结果进行了分析，结果表明本文的分析方法符合实际情况，是切实可行的，为分析和设计高生存性通信网络提出了统一的可实现的方法．This paper presented the general methodology of quantitative analysis for Disaster based SDH/ATM bidirection self healing ring network survivability performance,and derived the survivability function in closed form for SDH/ATM Bidirection Self Healing Ring (BSHR) under link and node failures and multiple failures.Various single value survivability measure such as the worst case survivability and expected survivability etc.can be easily obtained from the derived survivability function.The analysis of the result of derived survivability function show that the methodology in this paper is feasible for analyzing large scale disaster based survivability and designing cost effective high survivability communications network.
