In this paper, we study how to distribute cache sizes into a tree structured server for transmitting video streams through videoon-demand (VoD) way. We use off-line smoothing for videos and our request rates are distributed according to a 24 hour audience curve. For this purpose we have designed a slotted-time bandwidth reservation algorithm, which has been used to simulate our experiments. Our system tests the quality of service (QoS) in terms of starting delay, and once a transmission has started, the system guarantees that it will be transmitted without any delay or quality loss. We tested it for a wide range of users (from 800 to 240 000) and also for a different number of available videos. We demonstrate that a tree structured system with uniform cache sizes performs better than the equivalent system with a proxy-like configuration. We also study delay distribution and bandwidth usage in our system on a representative case.
