A teaching experiment design of spn based on modeling video-on-demand system

Modeling real system is one of the difficult and important parts as teaching the knowledge of computer system performance evaluation. This paper takes the modeling of video-on-demand (VOD) system for example, and uses the stochastic Petri nets (SPN) introduced in Prof. Lin Chuang's book [6] to discuss the application of SPN theory in detail. Through the experiment results, we also analyze some performance metrics with various arrival rates. To teach and apply the knowledge of SPN, the SPN theory will be intuitive and easily understood if it can be applied to the modeling process of an easy instance.
