Abstract

Abstract: The execution time of a service may fluctuate due to the variety of network, CPU, disk I/O and workloads, which will affect the makespan of the composite service. It is crucial to study the probability distribution and influencing factors of the real makespan to guarantee the performance of the composite service. This paper adopts directed acyclic graph (DAG) to describe the composite service. Also, with the goal of evaluating the variety degree of the makespan, we propose a temporal robustness metric for composition services. Through the rigorous analysis, we can find the boundary of this metric. By the analysis of simulation, we explore the variety of several factors to this metric, such as the distribution and fluctuation of service execution time, the number of simple services in the composition service. The experiment results lay the theoretical foundation for the analysis and design of robustness service composition.
