对等网络Chord模型的分区管理策略

A District Management Strategy for P2P Chord Model

提出的一种对等网络Chord模型的分区管理策略,能使节点标识包含区域位置特征信息,进而提高了结构化哈希算法中覆盖层逻辑排列和底层物理网络的匹配程度.该策略使全局对等网络搜索实现到区域查询,尤其在资源查询比较频繁的区域,搜索效率比传统Chord模型有显著的优势.实验结果表明,分区管理策略在平均路由跳数、查询时延和带宽方面都有显著的优点.

A district management strategy based on Chord model of peer to peer （P2P） network was proposed, in which nodes＇ identities contain district location information to enhance the matching degree of the structured Hash algorithm between the logical overlay and underlying physical network. The strategy has realized P2P search from globe to region, especially in regions where the resources research become more often. Search efficiency has significant advantages than the traditional Chord model. The simulation results show that the district management strategy has remarkable advantages in average routing hops, delay and bandwidth.
