针对目前网格系统在实现机制、技术支持上异构性大,缺乏互操作,提出一种基于虚拟化技术的异构网格互操作机制(Virtualization-based Grid Interoperation,VIGI).VIGI通过构建虚拟管理层和插件模块,实现异构网格互操作,同时保证各网格平台的独立性.GOS、CGSP是中国国家网格(CNGrid)和中国教育科研网格(ChinaGrid)两大异构网格支撑中间件.基于VIGI,实现了CNGrid和ChinaGrid互操作.实验验证虚拟化技术在异构网格互操作中的可行性和有效性.
Aimed at the heterogeneity and lack of interoperability of grid system in implementation mechanism and technical support, a Virtualization-based Grid Interoperation (VIGI) mechanism based on virtualization technology is proposed. Management and plug-in modules to achieve heterogeneous grid interoperability, while ensuring the independence of the grid platform.GOS and CGSP are two major heterogeneous grids of China National Grid (CNGrid) and China Education Grid (ChinaGrid) Based on VIGI, CNGrid and ChinaGrid are interoperable, and the feasibility and effectiveness of virtualization technology in heterogeneous grid interoperation are experimentally verified.
