摘　　要：为评估光网络的脆弱区域,需要构建研究光网络的脆弱性模型。为此,从攻击的类型出发,构造了光网络概率故障模型;在概率故障模型下,提出采用贪婪算法找出单个攻击或k个攻击同时发生时光网络的脆弱区域。以此为基础,在Matlab环境下,对一实例进行了仿真研究,其仿真结果符合实际情况,可应用与光网络的脆弱性评估。In order to estimate vulnerable regions of the optical network, the vulnerable model of the optical network should be built. Based on the types of attack, the probabilistic failure model is constructed; and under the probabilistic failure model, the greedy algorithm is used to find the vulnerable regions in the case of single attack or k simultaneous attacks. Finally, an example is simulated and researched in Matlab; the simulation results is accordance with the practical situation. So the model can be used in vulnerability estimation of the optical network in future.
