基于VCA模式的网格信息集成策略

The grid information integration scheme based on virtual client access mode

提出基于虚拟客户端访问(virtual client access,VCA)模式的网格异构信息集成策略,以松耦合的架构提供了系统无关的信息资源封装模型.该模型将异构信息系统的虚拟客户端封装为网格服务,使网格能够以与物理客户端相同的方式和信息系统进行交互,在保证信息集成效率的同时,实现了网格平台和本地信息系统的访问控制模式和作业管理方式的无缝结合.试验结果表明,基于VCA的模式有效地保证了信息的集成效率,适合于复杂网格环境下的集成应用.

VCA(virtual client access) based grid information integration strategy is proposed in this paper that brings forward one efficient application framework with loosely coupled architecture.It encapsulates the virtual clients that are realized based on the API of the information systems as grid services to enable the grid can access the information systems as real client.VCA mode can be combined with local access control and task management seamlessly,and solve the resource conflicts between grid and local users so as to support the information sharing and cooperation widely and efficiently.The experiment shows that VCA modes can support the information sharing and cooperation widely and efficiently.
