Dynamic fault-tolerance service framework for grid

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 fault-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.
