边的故障可通过级联效应给网络带来灾难性后果.如何减弱或避免故障带来的影响成为目前研究的重点.当网络中某边出现故障后,需对故障边的边权进行分配,该文提出一种优化分配模型,模型中考虑了对点权大的节点的保护,常用的比例分配方案是优化分配模型的一个可行解.实例分析表明,采用优化分配策略有时可完全避免级联失效的发生,并指出不同的攻击策略下,易选取不同的故障边边权分配方案.
The side fault can bring disastrous consequences to the network through the cascade effect.How to reduce or avoid the impact of the fault has become the focus of the present study.When a side of the network fails, the edge of the fault needs to be allocated, In this paper, an optimal allocation model is proposed, in which the protection of nodes with large node weights is considered, and a common proportional allocation scheme is a feasible solution to optimize the allocation model.Example analysis shows that the optimal allocation strategy can sometimes avoid cascading Failure occurred, and pointed out that different attack strategies, easy to choose different fault distribution rights of the program.
