Abstract 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.
