Abstract
The video-on-demand (VOD) is one of the most potential services of internet applications. In this paper, a load balanced PC-Cluster for implementing the VOD server has been proposed to offer the video-information to users efficiently. In the proposed scheme, two-Tier model has been adopted in the systematic architecture. The PC-Cluster is used to be the storage system of the VOD server and the load balancing mechanism in the proposed system is based on the Least-Connection-First algorithm. For enhancing the sharing and balancing of the system load among video servers in the cluster, a video placement strategy has also been proposed. Accompany with the dynamically adjusted files in each video level, a dynamical cyclical video replacement mechanism is applied to replicate and allocate video files for improving the load balance of the system. From the experimental results, we can see that a better load balance of the system can be achieved by applying the proposed scheme.
