Using Monte Carlo Simulation to Evaluate the Reliability of Web Services Systems
LU Xinda · Dianzi xuebao · 2002
The current research work considered nothing explicitly about the reliability problem for the multi-user system of random degree of parallelism,such as the Web Services system (WSS) .By modeling WSS as architectural random server system,this paper proposes a simulation-based approach and its implementation system, Simurel. Making use of execution profiles and failure profiles, Simurel reveals good applicability and generalization. It can be used to solve architecture-based reliability assessment in a general way, no matter single-or multi-user. The results of several experiments indicate that Simurel bears good runtime performance.
