Abstract:
The evolving National Information Infrastructure (NII) represents
a seamless integration of existing and future networks. Users
in many promising new applications over NII, like digital libraries,
telemedicine and distance learning, need to access information
from remote multimedia servers. A Video-On-Demand (VOD) server
can be considered as a simple multimedia server. We will first
discuss our effort on constructing a NII testbed at the University
of Minnesota. Then a set of design issues and research results
on how to design efficient VOD servers will be presented. These
include methods to guarantee delay jitter-free retrieval of video
streams, data placement schemes to reduce video disk access time
and effective disk striping schemes for different video types.
We have also investigated video allocation schemes for a given
set of movies over multiple disk arrays such that an expected
number of concurrent accesses for each movie can be guaranteed.
A cost effective approach to serve a large number of concurrent
viewers for a popular movie is also proposed.
