An analysis and measurement of the equivalent model of serial queues for a load balancer and a Web server of a Web cluster with a low rejection rate

In this paper, we propose an equivalent model in a serial queue for representing the serial connection of the load balancer and a Web server of the Web cluster. We have set up an experimental Web cluster for doing some performance measurements. Moreover, we compare either the simulation results or the measurement results for the mean system response time of the serial queues forming the equivalent model which in turn has the supposition property derived by the use of two subsystems
