Abstract:
 This paper presents a simulation study of a
 video-on-demand system.  The focus of the study is the effectiveness
 of different caching strategies on a video-on-demand system with two
 levels of cache, RAM and disks, in front of a tape library.  Using an
 event-driven simulator, I show that caching was helpful in increasing
 the service capacity of the system.  On-demand caching showed its
 advantages especially when the requests were clustered around a few
 popular titles (in other words, there was temporal locality).
