我們採用稱為Linux虛擬伺服器（Linux Virtual Server）的負載平衡技術，透過高性能網路或區域網路互連的伺服器叢集（Cluster）系統來達成高可擴展的、高可用網路服務的有效結構。
另一方面，傳送及時視訊、音訊等的應用，也伴隨網路頻寬的增長而需求劇增。為因應趨勢及測試LVS在多媒體串流方面的支援，故於網頁叢集系統中加入串流服務。
但是該系統實際運作時，發生了流暢度(Smoothly)方面的問題。播放畫面出現嚴重的延遲，於是我們設計直接傳送的方式。當使用者自網頁上選定觀賞媒體後，便由客戶端直接與串流伺服器連線並進行後續串流媒體播放，從而改善了串流服務效能的問題。

We use load balance technique, Linux Virtual Server. Cluster server system construct the efficient structure own high scalability and availability through connecting with high performance network or LAN.
In addition, applications provide transmitting real-time video and audio are increasingly needed with network bandwidth increase. To fit the current trend and test the multimedia streaming support of LVS, we add streaming service into web cluster system.
But the playing of stream is not smooth, when the system is running. Streaming have serious delay and so we propose transmitting stream directly. When user had chose stream media from web then the client connect with streaming server directly and play the media continually, so we improve the performance of streaming.
