碩士 === 國立交通大學 === 資訊工程學系 === 84 === In video-on-demand(VOD) services, the video server plays an important role in handling the huge amount of video data andmanaging the users' requests quickly. Also, the design of the server must also take the cost into consideration. Similar tothe caching policy, we can use a hierarchical storage system to improve the performance of the system without greatly raising the cost of the server. The hierarchical storage system stores all videos in CD-ROMs which are managed by the jukebox and the disks are used as the cache of CD-ROMs. However, designing a video server is not a simple task since it involves complex interaction among the components of the server. In the design of some parts of a server, most researchers limit their simulation in a small range of the server since it is difficult to simulate the whole server. Hence, in this thesis, a simulation model is proposed for designers of video servers using hierarchical storage systems so that they can easily simulate their design using the simulation system with only little modification.
