Design And Implementation Of The Shandong CTT VOD System Based On LVS Technology

VOD(Video On Demand) is a multimedia technology and network technology to develop a product is a new information technology services. It satisfies people to watch their own programs, random access to the information needs of many of our lives and bring to facilitate learning. By conducting in-depth discussions on the VOD system, and in light of its own reality, Research and Implementation of the Shandong CTT VOD system.Shandong CTT VOD system from the main Web site, LVS load balancing, edia services, Distributed storage network components. When taken in the design of advanced streaming media technology, LVS load balancing technology, Distributed network storage technologies and the media document of the technology, and other mainstream technologies and advanced concepts, Web site has adopted a three-tier structure designed to achieve B/S, models ASP dynamic call from the realization of the right to operate the database and business logic of the calculation; LVS in load balancing system, Design based on dynamic load balancing negative feedback mechanism linking the minimum weighted scheduling algorithm; the use of distributed network storage technology to achieve the large-capacity storage media files; CDN technology used to complete documents to the media distribution system design and implementation.The idea is to design systems such as RM or RMVB format video or documents stored in distributed network storage systems. upon request, the location of system users, LVS use of the distribution strategy will be assigned to user requests for the best media server, re-circulated through the media, the media have a corresponding server to client and real-time decoding broadcast.VOD system is based on achieving the goal of this structure, and the use of cluster technology to be fully distributed architecture of the VOD System Design and Implementation of the Shandong CTT.Completed papers in the process, I would do the following : VOD system to conduct an in-depth analysis and design; The structural design of the program is given a VOD system, and the deployment of the major components : VOD system WEB, LVS load balancing, distributed network storage. document circulated to the media a detailed design and implementation;The system not only guarantee the realization of VOD users to watch the roadcast of speed and quality viewing; and achieve a balanced flow of information in the local nodes, Internet backbone bandwidth to resolve the issue of using CTT. increase the efficient use of bandwidth. It was good to the application and promotion of economic and social benefits.
