Design and Implementation of WMI based VOD Service for efficient Load Balance Policy

효율적인 부하 분산 정책을 위한 WMI 기반 VOD 서비스의 설계 및 구현

Cluster-based servers are utilized for large scale streaming services. These servers show good performance under fair resource usage balance policies between backend nodes. In this paper, cluster-based VOD servers are implemented based on WMI functions. Based on these functions, the information of resource usages in backend nodes can be exchanged and also the working states of cluster nodes can be monitored periodically. In experiences, we find motivations to design an effective load balancing policy. In addition, to provide reliable streaming services, the method to detect a partial failure in cluster-based servers is proposed.
