碩士 === 國立中正大學 === 資訊工程學系 === 84 === In this thesis, we'll discuss how a VoD server to control the total flow rate ofvideo streams by dynamic changing the QoS level of each user to make the interactive with the other elements of a VoD system possible. At first, we'll show why we choose the CBR model to transmit the MPEG stream from VoD server to users. And we'll explain how can a VBR consuming user avoid starvation under the CBR transmission model. Second, we introduce dynamic QoS level changing to make a VoD server has the ability to control the total flow rate of video streams. We also introduce two disk placement strategies to support dynamic QoS level changing. At last, we'll examine some characteristics of our method under these two disk placement strategies by simulation with a real video data.
