为了提高网格的智能水平和协调能力以及协同分布的网格服务,支持动态的计算环境和多变的用户需求,提出了协同智能网格CIG(cooperative intelligent grid).CIG以OGSA为基础,应用分布式人工智能和分布协调控制的理论和方法来研究和解决网格中如何高效准确地协同现有的网格服务以完成所面临的任务.文中描述了CIG的概念和体系结构,从社区/联邦式政策导向型的系统结构、领域自适应的中介服务协作机制和理性化协商机制等方面构建开放动态的CIG.CIG可以有效地组织各网格实体的协调、协商和合作,提高了服务组合的自动化程度和抽象层次.
To improve intelligent level and coordinative ability, cooperate with distributed grid services, and adapt to dynamic computing environment and variable user demands in the grid, cooperative intelligent grid (CIG) was proposed. CIG was based on OGSA, and the applied theory and methodology of distributed artificial intelligence and distributed coordinating control to improve the existing grid services' cooperativity and provide services to grid users more efficiently and accurately. The concept of CIG was introduced first, and followed by the description of the architecture of CIG, then the principles and methods for constructing an open and dynamic CIG with respect to the community/federal policy-driven system structure. The domain-adapting medium service collaboration mechanism and rational negotiation mechanism were discussed. CIG can effectively organize coordination, negotiation and collaboration among grid entities and improve the automation degree and abstract administrative levels of grid service composition.
