abstract = {The designers of
a large
scale video-on-demand system face an optimization
problem of deciding how to assign movies to
multiple disks (servers) such that the request blocking probability is minimized
subject to capacity constraints. To solve this problem, it is essential to
develop scalable and accurate analytical means to evaluate the blocking
performance of the
system for a given
file assignment. The performance
analysis is made more complicated by the fact that
the request blocking probability depends also on how disks are selected to serve
user requests for multicopy movies. In this paper,
we analyze several efficient
resource selection
schemes. Numerical results demonstrate that our
analysis is scalable and sufficiently accurate to support the task
of file assignment optimization in such
a system.}
