Video-on-demand (VOD) is one of the hottest and the most potential services of the broadband network applications. In order to offer the video-information service to numerous users nowadays, in this paper, a load balanced PC-Cluster for the VOD server system has been proposed. We adopt Two-Tier model in the systematic architecture, and use the PC-Cluster to be the storage system of the VOD server. The load balancing mechanism is based on the Least-Connection-First algorithm. Furthermore, a video placement strategy is also proposed in this paper to share and balance the loads among video servers in the cluster. Accompany with the dynamically adjusted files in each video level, a dynamically cyclical video replacement mechanism has been proposed to replicate and allocate video files for improving load balance of the system. The experimental results show that a better load balance of the system can be achieved by applying the proposed scheme.
