Abstract

In this paper we evaluate the influence of the network topological characteristics on the extent of losses after attacks. For that purpose, we use the ATRF (attack-to-random failure) multiplier. Modeling results show that when using a standard metrics of distance in path computations, the number of connections broken due to attacks on irregular networks is significantly greater, compared to random failures. This is true independent of the algorithm used for path finding.
