摘　　要：对目前P2P网络中集散节点现象进行了研究,阐述了对集散节点进行基于超立方体结构的分布式处理控制思想,提出了一种全新的通过控制P2P网络的逻辑拓扑结构来避免集散节点形成的思路,给出了控制模型以及实现控制模型的具体算法,并对算法进行了复杂度分析,最后通过仿真证明了本控制模型能有效控制网络中集散节点的形成。所以本控制模型能提高P2P网络抗协同攻击的能力,增强网络的健壮性,从而达到保障P2P网络可持续健康发展的目的。This paper researched into the hubs in P2P networks, and presented a new method to avoid generating the hubs in the networks by controlling the logical topology structure of P2P networks. It firstly introduced the controlling ideas about distributing the hubs by using super-cube structure. Then, it disclosed and interpreted the controlling model, and gave out the concrete method to carry it out. Finally, it validated the controlling model via simulations and the simulation results demonstrated that the work was effective to control the hubs in P2P networks. Thus, this model could improve the network competence to defend against coordinated attacks, promote the network robustness, and ensure that the network would develop continually and healthily.
