P2P网络分层模型SHDN的研究与设计

在分析和总结主流对等网络模型的基础上，建立一个新型高效的、负载均衡、可扩展的、动态的对等网络分层路由模型——基于超级节点的分层DHT网络（SHDN），旨在为用户提供用户的准确定位、用户的组群管理和文件资源传输等基本的信息服务功能。对SHDN模型的路由算法进行了详细的设计。最后，通过仿真试验对SHDN模型的合理性和路由效率进行了验证和测试，基本上达到了预期的设计目的。

Research and design of P2P network hierarchical model SHDN

After the characteristics of the mainstream P2P network models were analyzed, a new hierarchical P2P network model called SHDN (Supernode based Hierarchical DHT Network) was designed. It features load balance, extensibility, dynamic character and higher efficiency. SHDN can offer the basal information services such as precise location of the users, administration by clusters, files transmission and so on. The design of the SHDN network model was described, and the rationality and the routing efficiency of SHDN were tested by emulation.
