P2P网格数据银行模型设计及安全访问策略

P2P Grid Data Bank Model Design and Secure Access Policy

针对于传统网格在资源发现和资源整合方面的不足,提出了网格技术与P2P(Peer to Peer)技术之间进行协同和互补,构造了一个四层的基于P2P协议的网格电子数据银行模型。运用P2P协议进行点对点通信,进行消息路由和资源发现的优化,利用网格技术进行身份认证,资源调度和并行计算,加入了端点接入和通信安全策略。该模型可以解决网格的单点失效、资源搜索和安全接入保密通信等问题,同时增强网格的可扩展性。

This paper proposes grid and P2P(Peer to Peer) technology synergies and complementarities,and constructs a four-grid-P2P electronic data bank model to makes up the shortage of the traditional grid for resource discovery and resource integration.The use of P2P protocols point to point communication to completes message routing and resource discovery for the optimization.The use of grid technology to finishes authentication,resource scheduling,and parallel computing,and the model joins the endpoint access and communication security policies.The model can solve the single point of failure of the grid,resource search,and security issues such as access to secure communications,while enhance the scalability of the grid.
