웹캐스팅에서의 VOD 채널 운용시스템 모형 설계

  In 21th century, The development of an information communication technique brought the change of an information circulation structure. it was VOD service. In conventional video-on-demand systems, video data stored in a video server for delivery to multiple receivers over a communications network. This pager studies a parallel video server architecture that exploits server level to achieve incremental scalability. First, the architecture employs data striping at the server level to achieve fine-grain load balancing across multiple servers. Second, a client-pull service model is employed to eliminate the need for inter server synchronization. Third, an linear-scheduling algorithm is proposed to further control the instantaneous load at each server so that linear scalability can be achieved. This is to investigate the design of VoD systems using parallel-server architectures.
