海底光缆(海底光缆)是一种大型的互联互通基础设施，在国际通信、网络物理系统乃至国家安全中发挥着重要作用。尽管海底光缆网络中断可能造成严重的后果，但对其脆弱性的研究并未引起太多关注。提出了一种定量衡量海底光缆网络脆弱性的方法，并对即将开通的跨北极光缆系统对大陆中国海底光缆网络的影响进行了评估。为解决这一问题，首先，建设大陆中国的海底光缆网络。在此基础上，提出了基于复杂网络和地理空间视角的方法来模拟不同攻击下网络特征值的变化，定量分析网络脆弱性的变化程度。利用该方法，对我国大陆中国所在的海底光缆网络在跨北极光缆系统建设前后的脆弱性进行了比较。结果揭示了中国大陆海底光缆网络的关键节点国家和海上通道，显示了TAC系统的意义。
The submarine optical-fiber cable (submarine cable) is a large connectivity infrastructure, which plays an important role in international communication, cyber-physical systems, and even national security. Although submarine cable network interruption may cause serious consequences, researching its vulnerability has not attracted much attention. This paper proposes a quantitative method to measure the vulnerability of the submarine cable network and evaluates the influence of the upcoming trans-Arctic cable (TAC) system on the submarine cable network of mainland China. To address this issue, first, the submarine cable network of mainland China is constructed. Further, methodology based on complex network and geospatial perspective is proposed to simulate the changes of network eigenvalues under different attacks and to quantitatively analyze the variation degree of network vulnerability. With the proposed method, the vulnerability of the submarine cable network of mainland China before and after construction of the trans-Arctic cable system is compared. The results reveal the key node countries and sea channels of the submarine cable network of mainland China and show the significance of the TAC system.
