摘要: Recently, the video server plays an important role in VOD or near VOD system. In general, a good video server can not only provide start/stop operations forplayback of each request, but also support VCR functionality. In this thesis,we will propose an effective data placement method, called Enhanced-Segment- Placement (ESP) scheme, to support VCR operations built in our video servermanagement platform. Its placement pattern provides uniform load balance for arbitrary retrieval rate as well as normal rate playback. Some distinguishedfeatures are explored by appropriate analytic approach. Meanwhile, experimentsshow that our scheme will have higher throughput, lower reject probability as well as better load balance factors compared with other methods. The detaileddescription of ESP scheme and its implementation and evaluations will be givenin the literature.
