| Summary: | 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.
