Collapse by Cascading Failures in Hybrid Attacked Regional Internet

Free registration required

Executive Summary

To study the cascading failures and robustness of Internet, measuring topology of regional Internet with monitors is performed first. The mathematical transformation of measured results into matrix is introduced to set up a simulation platform for further experiments. By setting up various simulation parameters, the authors found that Internet is to some extent having the performances of highly resistance to random attacks and easily collapse while under intentional attacks. And in hybrid attack situations, Internet is also quite fragile no matter what ratio of intentional attacks over the random ones is. Besides, they find that networks with high loads would easily result in more damaged networks even under the same attacks.
