选择网络流量传输成本作为海底光纤系统的脆弱性测度指标,提出了一种基于双层优化模型的海底光纤系统脆弱性分析方法,能够识别出特定毁伤预算下的脆弱点,并能对受损情况下重新分布的网络流量进行量化分析。最后,通过某假设地区的两大海底光纤系统验证了方法的有效性,探讨了动态脆弱性的一些特征并给出了相应的保护策略。
This paper chooses network traffic as the vulnerability metric for global undersea cable infrastructure and proposes a vulnerability analysis method based on bi-level optimization theory which can identify the most vulnerable parts of the system under specific damage budget and take quantitative analysis for the rerouted traffic because of the damaged parts. Finally, the vulnerability analysis method is verified with two undersea cable systems in a certain hypothesis region, and characteristics of the dynamic vulnerability and corresponding protection strategy are discussed.
