网络生存性的测度

基于对现有生存性测度方法优缺点的考虑,提出了以网络在整个破坏过程中的网络连通度的估计为基础的一种新的基于网络拓扑结构的生存性测度方法。结合实例,给出了在节点失效、链路失效和节点链路混合失效3种失效模型下网络生存性定量分析方法和优化方法。从实例分析中容易看出,文中所提出的分析、优化方法是评估网络生存性和设计高生存性网络的一种相对简单而有效的方法。

Survivability Measure for Networks

A new survivability measure which is based on topological structures of networks is presented in this paper. Based on the measure, the method of survivability quantitative analysis and optimization under node, link and multiple failures is given together with case studies. Through the case studies, we can easily obtain that the method presented in this paper is more simple and effective for estimating the survivability of networks and designing networks with high survivability.
