| 摘 要： | 通过整合基于服务器/客户机模式的集中式查找方案和基于对等计算模式的分散式查找方案，提出了一种混合式查找方案。该方案既有可扩展性、高容错性和自组织性等分散式查找方案的优点，又有利于集中管理和控制，安全性好等集中式查找方案的优势。仿真实验结果表明，该方案的RDP指标优于常规的分散式查找方案，实际查询时间开销更是远远少于常规的分散式查找方案。

| Abstract: | Presents a hybrid data location scheme by combining centralized location scheme,which based on C/S model with decentralized location scheme based on Peer-to-Peer computing model.This scheme has not only some good features of the decentralized schemes,such as scalability,fault-tolerance, and self-organization,but also some advantages of the centralized schemes,such as centralized management and control,security,etc.Simulation experiment results show that the Relative Delay Penalty (RDP) of this scheme is better than those of conventional decentralized location schemes and the actual location time is far less than those of conventional decentralized location schemes. |
