Vulnerability structure of global submarine optical cable network and evaluation of regional survivability
Submarine optical cables play a vital role in social economy development, and national defense and security. Submarine optical cables are always facing the risk of natural or man-made damage. However, the current researches of the vulnerability of submarine optical cable network are still limited to local network and national scale. In this article, we construct the global submarine optical cable network with information ports as nodes, and design a set of evaluation method combining complex network theory and simulation tools to analyze network vulnerability, classify hub information ports, and measure regional survivability in turn. The research results are as follows: 1) The submarine optical cable network has typical scale-free and small-world characteristics, and its vulnerability structure, which is not significant under random attacks but significant under deliberate attacks, is confirmed by simulation. In the deliberate attack mode, the submarine optical cable network is more sensitive to intermediary centrality attacks than point-degree centrality attacks, and it can be assumed that the transit and bridging functions of the information port are more critical to the vulnerability structure of the network. 2) The submarine optical cable network shows three states of “connectivity damage” “partial collapse”, and “complete collapse” in order with the increase of attack level. Accordingly, 66 hub information ports are identified and classified into 3 levels. The hub information ports appear the characteristic of polar core structure in the submarine optical cable network, and echo the main sea lanes, which are the main reasons for the vulnerability structure of the submarine optical cable network. Singapore, Cape Town, England’s west coast area, Florida and other information ports and their surrounding waters need to be focused on security. 3) The redundant connections of hub information ports make the submarine optical cable network have a certain self-regulation mechanism. However, the regional survivability levels vary greatly in space, specifically showing that Europe and North America have higher survivability levels, while East Asia, South Asia and South-Central Asia have midstream destructivity levels, Central America and North Asia have the lowest destructivity levels, and there is still much room for optimization. Overall, the research results can provide reference and decision support for the optimization of submarine optical cable network structure.
