Abstract:Traditional fault-tolerance approaches often result in low efficiency of service composition in integration networks. In this paper, a fast and reliable fault-tolerance approach is proposed for service composition in integration networks. This approach firstly adopts fuzzy logic to perform service retry when the transient faults of service occur. And then multi-attribute decision-making theory is employed to carry out service replicate when the permanent faults of service occur. Finally, an improved particle swarm optimization algorithm is used to implement service compensation when the permanent faults of service arise. The experimental results based on real data sets show that the proposed approach is superior to other approaches in terms of fault handling rate, fault handling time, and composition optimization.
