地理分布的光网络脆弱性评估研究

Research on assessing optical network vulnerability from geographical distribution

从光网络地理分布模型出发,采用通用模型下的最坏圆形切割算法,对网络拓扑结构进行了建模和仿真,计算出了网络的最坏圆形切割集,进而算出了网络的节点风险概率,并根据节点风险概率对网络的脆弱性做出了评估,这些工作对提高光网络的抗毁能力具有一定的参考意义。

On the basis of an optical network geographical distribution model, we conduct modeling for and simulation of a network topographical structure by adopting the WCGM algorithm and find out the aggregation of worst circular cut of the network. Furthermore, we compute the network node risk probability and assess the vulnerability of the network on the basis of the node risk probability. This work is useful for improving the survivability of optical networks.
