A Design and Development of a Near Video-on-Demand Systems.

Recently, Video-on-Demand (VoD) services have attracted great attention. In conventional VoD services, the processing load and the communication load on the distribution server increases as the number of the clients increases. To distribute the loads on the distribution server, some researches focus on Near VoD (NVoD) systems. Most of the researchers investigated the waiting time arose in NVoD systems using a simulation program because it is difficult to develop the NVoD systems that work on actual situations and there are no opened NVoD systems. However, the simulated waiting time can be different from the actual waiting time because the simulators cannot completely reflect the actual situation. The simulation model that removes some trivial processing or communication flows gives different evaluation results for the actual situations. In this study, we design and develop an NVoD system to investigate the performances such as the waiting time and the interruption time in actual situations.
