ABSTRACT
Video-on-Demand (VOD) has been gaining increasing popularity in recent years. Previous load balancing algorithms in video servers mainly focus on two resources: storage and network bandwidth. However, with better network and cheaper disk, disk I/O becomes more critical in reducing user-perceived latency. In this paper, we propose an algorithm for disk I/O balancing in centralized video servers. Analytically and by simulations we show that our algorithm decreases total disk I/O amount by 30% to 50% and provides better load balancing performance and higher cache hit ratio compared with round-robin and random selection algorithm.
