We consider and compargon the results for two di erent network topologies: the ErdosRà nyi random graph and the Barabà siAlbert scale-free network. We also hash out brie y e a a dynamical regulate recently proposed to father into account the dynamical re distribution of loads after the initial malign of a whizz node of the network. c 2004 Elsevier B.V.

Introduction Most of the talk/transportation systems of the actual world can be represented as complex networks, in which the nodes are the elementary components of the system and the edges connect duplicate of nodes that mu tually interact exchanging information. To q! uote a few examples: in the Internet the nodes are the routers and the edges (or arcs) are the cables connecting couples of routers; in an electrical world power grid the nodes are the substations (generators or distribution substations) and the edges are the transmission lines; in a city alley system the nodes are the crossings and the ?
