The paper presents a simulation model of a generic system to support multimedia-on-demand services over an ATM network. The simulation has been performed using an object-oriented approach. Discrete event system specification (DEVS) methodology has been used in the design and implementation of the simulation. This simulation approach also helped in the development of a modular, re-usable and easily extendable model of a multimedia-on-demand system. Also, this approach is shown to be very useful in adapting the basic model to simulate any of the multimedia-on-demand services mentioned above. To illustrate this, we have simulated a movie-on-demand service using our generic multimedia-on-demand simulation model. We have demonstrated the real-time nature, scalability and cost-effectiveness of a movie-on-demand system based upon our generic multimedia-on-demand system. This model will be useful for studying the performance of facilities such as movie-on-demand, interactive network games, multimedia libraries etc.
