Based on service-oriented grid environment,the paper put forward a method of resource reservation which to construct a resource reservation tree(RRT).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.Furthermore,three strategies of reservation were designed according to different QoS requirements of users',on the basis of which, the algorithm TTL-RTA based on RRT was presented in the paper.Related performance analysis and simulations for the algorithm indicate better efficiency and reliability.
