摘要: 地图库管理着海量的空间数据,传统的客户机/服务器(C/S)架构已经不能满足日益增长的数据共享需求。提出一种基于peer-to-peer(P2P)架构,以分布式哈希表(DHT)和空间数据索引技术为基础的方案,把地图库中的空间数据自动发布到P2P环境中进行管理。试验结果表明,P2P架构能够支持大量用户对地图库的并发访问。

Abstract: Map library manages magnanimous spatial data,the increasingly requirements of data share have gone beyond the capabilities of traditional Client/Server(C/S) architectures.This paper gives a new solution that based on peer-to-peer(P2P) architecture,takes the Distributed Hash Table(DHT) and spatial data index as foundations,distributes the spatial data of map library into the P2P environments and manages them.Results of experiments show that P2P architecture can support a large number of users access map library at the same time.
