A capacity planning model of unreliable multimedia service systems

To analyze the performance of multimedia service systems, which have unreliable resources, and to estimate the capacity requirement of the systems, we have developed a capacity planning model using an open queueing network. By acquisition of utilization, queue length of the resources and packet delay, and reliability of the systems, we have derived the service capacity of the systems along with the arrival rates of clients and the failure rates of the resources. We have validated the proposed capacity planning model by comparison of analytic results with simulation output. 2001 Elsevier Science Inc. All rights reserved.
