网络资源管理的Grid和P2P集成方案及其关键技术分析

Grid and P2P integrated project and key technologies analysis of network resource management

网格计算(Grid)偏重通用协议,考虑共享的基础设施以及互操作问题;对等计算(P2P)则关注垂直集成解决方案.而开放网格服务体系结构(OGSA)为网格与P2P的集成提供了一个框架,使网格与P2P能更好地聚合在一起,从而更有利于网格的扩展性、自治性和动态性.对此,全面介绍了网络资源管理的Grid与P2P集成方案的常见模型,分析了这些模型中的几个关键问题,并指出了今后的研究方向.

Grid system focuses more on universal protocol, shared infrastructure and inter-operation. By contrast, peer-to-peer computing （P2P） system tends to be vertically integerated solutions. However, open grid services architecture （OGSA） provides a framework for integrating grid and P2P to aggregate Grid and P2P, and so that it is beneficial to scalability, autonomy and dynamic of the grid. Therefore, some models integrating grid and P2P of network resource management are throughly introduced, and some key problems in these models are analyzed in detail. Finally, the further research directions are presented.
