摘　　要：错误的频繁发生已经成为阻碍网格稳健发展和大规模应用的主要障碍之一,网格系统的容错性研究显得尤为重要。根据网格计算的特点,提出了网格环境下的特殊容错需求;结合用户的服务质量要求,建立了包括网格错误检测与网格错误管理的动态容错服务架构,阐述了错误检测服务与错误管理服务的组织结构、各组成模块的具体功能;最后,给出了一个完整的容错服务实现过程。Frequent occurrence of fault had been one of the primary obstacles to baffle the moderate development and scalable application of grid, it became extraordinarily important to research fauh-tolerance of the grid system. According to the characteristics of grids, this paper summarized the special fault tolerance requirements of grid environment. Combined with the user＇ s QoS demands, established dynamic fault tolerance service architecture, which included grid fault detection and fault management services. Furthermore, illustrated the framework of the fault detection service and fault management service . At last, proposed an entire implementation procedure of fault tolerance service.
