Research On Scalable Streaming Media Server System Based On Open-frame

Along with the rapid evolution of the Internet, streaming media service such as IPTV and video-on-demand becomes more and more popular, so we need a high performance and flexible streaming server and system to support these services. The Real,Microsoft and Apple companies programs require high-cost support. According to the understanding and analysis of streaming media technology and product, we present a scalable streaming server system to expand media service based on open-frame. By using some of the existing open source projects, we can improve the streaming media server performance and scalability.The main content is as follows:①This paper at first introduces the streaming media technology development and the cluster technology. Then it proposes the requirement of streaming media server itself and streaming media service system.②After detailed analysis of LVS and Darwin server systems, we design a scalable streaming media server architecture based on the two open source projects. Then it introduces its working principle and data flowing.③Based on the expansion of the streaming media server architecture, the paper The paper proposes the permission control strategy based on user priority and the permission algorithm based on the capacity control and the dynamic feedback scheduling mechanism.④According to the function of streaming media sever, the paper improves the data storage mechanism and streaming media services strategy. It proposes the storage mechanism based on program popularity and streaming media services strategy based on threshold.⑤After testing the system concurrent number and the server export, the result indicated the system scalability and load balancing.The scalable streaming server system improves the services support to users and makes the hardware and software of streaming media server system cooperates much better. It should be a good solution to small-scale media services program.
