Based on communication network as the background, this paper established a model to capture the cascading failures. The relationship between the local routing congestion information mean dynamics. In this model, according to new congestion function defined by each node (dynamic weight) is put forward based on the local congestion information, routing policy with adjustable parameters. On the BA scale-free network and ER random discusses caused by deliberate attacks on the network of cascading failure behavior. Through numerical simulation main findings, based on the new measure network robustness index (namely, critical production rate, there is a free flow to the phase change of the cascade configuration), the optimal value of existing routing parameters to achieve most robust network and the optimal value related to the network topology.
