【 中文摘要 】本发明是一种HP2P网络中群的分裂与合并方法。本发明主要针对HP2P网络的上下层结点数量比例过大或过小会导致网络性能下降的问题， 提出一种HP2P网络中群的分裂与合并的方法， 通过计算结点间的亲和度将具有高亲和度的结点组织在一起， 以使网络保持恰当的层间比例， 从而维持HP2P网络的高效率、低负载和可扩展性。在群的分裂与合并方法中， 将亲和度因子放在消息中进行传递， 使得亲和度的计算简单， 容易实现。在群分裂与合并后网络的拓扑结构还可以得到一次优化。本发明可应用于HP2P网络， 还可应用于其它相似网络上的分裂与合并过程。
【 英文摘要 】The invention provides a method for splitting and combining clusters in an HP2P (hybrid hierarchical peer-to-peer) network. Aiming to solve the problem of the decreasing network performance caused by too large or too small ratio of the node numbers in the upper and lower layers in the HP2P network, the invention provides a method for splitting and combining the clusters in the HP2P network. Nodes with high affinity can be organized together by calculating the affinity among the nodes, so that the network can maintain a proper interlayer proportion, thus the HP2P network can be kept with high efficiency, low load and extensibility. In the method for splitting and combining clusters, an affinity factor can be transmitted in the message, so that the affinity can be simply calculated and is easy to realize. Besides, the topological structure of the network can be optimized after the splitting and the combination of clusters. The method provided by the invention can be applied to the HP2P network as well as the splitting and combination process of other similar networks.
