The Research on Fault-tolerance Method for Grid Resource Reservation

Resource Reservation is an important technology to gurantee Quality of Service of users' requirements,the faults could lead reservation to fail.The paper put forward a method of resource reservation which constructing a Resource Reservation Tree with corresponding algorithm.If the resource reserved before turns into invalidation, the substitute can be found directly in RRT and needn 't to initiate a process of discovery and negotiation again.The method can avoid a failure of resource reservation and advance its reliability. Finally, related performance analysis for the algorithm was done.
