Abstract: It is one of the goals of designing peer-to-peer network to minimizing the resource consumption. The article constructs the abstract load model for cluster-based peer-to-peer network. The dynamism of system is investigated based on the collected data in the experiment. The optimal numbers of clusters are respectively obtained under the circumstances in which nodes have the same capability and in which nodes are heterogeneous and nodes keep arriving and leaving. The optimization can give a judgment for design and construction of peer-to-peer system.

Key words: Cluster, Coustructed peer-to-peer network, Load optimization

摘要： 减少系统的资源消耗是对等网络设计的目标之一。该文对基于聚类的对等网络建立了负载的抽象模型，根据实际系统中采集的数据分析了节点的动态特性，并分别在节点能力相同、节点的能力的异构和系统处于动态的情况下，对聚类的数目进行了优化分析，为设计和构造对等网络提供了依据。
