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.
