A Resource Reservation Algorithm with Fault-tolerance in Service-oriented Grid Environment

摘要

Based on service-oriented grid environment, the paper put forward a method of resource reservation which constructing a resource reservation tree. If the resource reserved before turns into invalidation, the substitute can be found directly in the tree and needn’t to initiate a process of discovery and negotiation again. Furthermore, three strategies of reservation were designed according to different QoS requirements of users’, on the basis of which, an algorithm of TTL-RTA was presented in the paper. Related performance analysis and simulation for the algorithm indicate better efficiency and reliability.
