Dependability Analysis of Parallel Video Servers Using Fault Injection Simulation

In recent years, significant advances in computers and communication technologies have made multimedia services feasible. As a result, various queueing models and cost models on architecture and data placement for multimedia server have been proposed. However, most of these models do not ev uate dependability of systems. In the design phase of a system, simulation is an important experimental ns for performance and dependability analysis. Fault injection simulation has been used in evaluation of dependability metric. In this paper, we develop fault injection simulation model to analyze dependability of parallel video servers. In addition, we evaluate reliability and MTIF(Mean Time To Failure) of systems by using the simulator.
