摘　　要：开放网格服务体系(OGSA)需要可扩展和可伸缩容错机制,以解决不同需求,比如多样故障处理策略及故障处理策略和应用代码的分离.本文提出了一种基于OGSA的错误检测框架,根据用户需求,检测算法可以向应用提供错误检测服务.最后,本文进行了性能分析和试验评估,结果表明本文提出的方法能够满足多样和动态的网格应用.Open Grid Services Architecture （OGSA） requires scalable and flexible fault tolerant mecha- nisms to address different requirements such as support for diverse failure handling strategies and separating failure handling strategies from application codes. In this paper, we propose a failure detection framework based on the OGSA. An adaptive failure detection algorithm is presented, and according to users＇ demands,it can provide application with failure detection service. At last, we put forward performance analysis and experiment evaluation, and the result shows that the method proposed in this paper satisfies application in grid with diversity and dynamic.
