Adaptive Fault Detection Strategy in GRID Based on OGSA

Open Grid Services Architecture (OGSA) requires scalable and flexible fault tolerant mechanisms 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.
