Data allocation algorithms for distributed video servers
James Z. Wang, Ratan Kumar Guha · 2000
In this paper, We discuss the server level data allocation problems in the distributed Video-on-Demand systems. We proposed two data allocation algorithms, Bandwidth Weighted Partition (BWP) algorithm and Popularity Based (PB) algorithm, based on the bandwidth and storage capacity limits of the distributed multimedia servers. We compare those two algorithms with the traditional Round Robin (RR) algorithm. The analysis and simulation studies show that PB algorithm is a simple and practical video data allocation algorithm for the distributed video servers. It provides near optimal system performance in any system condition.
