为解决级联失效网络负载重分配问题，提出了一种将网络局部信息和动态信息相结合的负载动态重分配策略． 该策略根据节点的度与节点实时处理能力计算节点权重，并以此依次进行负载重分配;同时，按一定比例选取失效节点暂停工作，其负载重新分配进程相应停止． 在 BA 无标度网络、WS 小世界网络和 EＲ 随机网络上的仿真结果表明，在一定的参数条件下，相对于介数分配策略与度数分配策略，动态重分配策略通过降低网络整体负载率、优化网络实时流分布缓解级联失效的效果更为明显．

In order to implement load reallocation in cascading failure networks,a dynamic reallocation strategy combining both local and dynamic network information is proposed.In this strategy,the weight is computed according to the degree and real-time processing ability of a node,and is used to reallocate load in turn.At the same time,according to a certain proportion,some failure nodes are selected to suspend their function and their load reallocation processes stop accordingly.Simulated results in BA scale-free network,WS small-world network and ER random network show that,under certain parameter conditions,the proposed dynamic reallocation strategy is superior to betweenness distribution strategy and degree distribution strategy because it is more effective in alleviating cascading failure by reducing the overall network load rate and optimizing network's real-time streaming distribution.
