摘要
网格是网络与异构环境中基于Web服务的分布式网络计算系统。从计算机网络体系结构的观点来探讨网格与计算机网络和Web服务的关系,通过对基于Web服务的网格服务体系结构和OSI/RM框架的对比分析,提出了将实现开放式网格服务结构(OGSA)的计算机系统划分为OSI/RM域内的部分和对OSI/RM不可见部分,从而理清了网格服务体系结构的层次结构与计算机网络层次结构的异同。
Grid service provides a distributed computing service over heterogeneous network environment by taking the advantage of the Web Service. The relationship among grid system and network systems, especially the Web Service system, was examined in the perspective of computer network architecture. An emphasis has been given to clarification of Open Grid Service Architecture(OGSA), in which some of layers irrelevant to network functionality (outside of the scope of OSI/RM) were miss-represented in early documents.
