摘要
利用P2P技术可以解决在海量用户情况下Web GIS系统的服务器瓶颈问题。如何在P2P环境中管理空间数据是一项刚刚起步的研究工作,还没有系统的理论体系。对P2P环境下空间数据管理的研究状况进行了综述。介绍了Nap-ster架构以及协议,分析了其优缺点。基于Napster架构,设计了基于P2P的Web GIS系统架构,并对该架构进行了分析。最后对后期研究方向进行了说明。
It is possible to resolve the server bottleneck problem when so many people use Web GIS system with P2P technology. It is a beginning research work how to manage spatial data in P2P environment, it has not systematic theory system. This paper summarizes studies on P2P-based spatial data management and introduces Napster＇ s architecture and protocol, analyses its good qualities and bad qualities. This paper designs an architecture of Web GIS system based on Napster architecture and analyses it. At last, this paper tells the study direction in following research.
