Abstract: Peer-to-Peer overlay networks have various features such as robust wide area routing, efficient search, and selection of nearby peers. This paper introduces a new network model——CayNET that supports grouping, and defines a DHT protocol——CayNET DHT in the network model, puts forward its topology, describes progress of adding and exiting in CayNET DHT. Experimental results show that the protocol is effective.

Key words: CayNET protocol, grouping, Peer-to-Peer(P2P) network, Cayley graph

摘要： 针对P2P覆盖网络具有易于构建、管理灵活、可扩展性强等特点，该文定义一种支持分组的Cayley图的网络模型CayNET，阐述一个DHT协议——CayNET DHT和其拓扑结构，分析节点的动态加入和退出过程。实验证明了该协议的有效性。
