Cost optimal dimensioning of a large scale video on demand system
David Choi · 2002
We introduce a video distribution architecture where the prefix of the video is delivered on demand by a prefix server while the body of the video is broken in equal length segments and each segment is periodically transmitted by a central server. The combination of open-loop distribution for the video body and closed-loop multicast transmission for the video prefix makes the overall system highly scalable and very cost-efficient.
