The Research On Key Techniques Of MediaSwitch Streaming Media System Based On CDN

With the development of the network technology, communication technology and the multimedia technology, the Streaming Media has gradually become the mainstream of the use of the internet, and boost the reform of the whole structure of the internet, as well as pushing the development of the information economy, the Streaming Media is playing an important role in the field of spreading internet media. But the development of the CDN technology provides a best solution for the use of wide band Streaming Media. The research of the thesis is one of the hot pot in the field of computer science at present, which has a good prospect.First of all, the thesis explicates the knowledge related to the Streaming Media, including the Streaming Media concept, the principle of the Streaming transmission etc. On the base of above mentioned, the thesis puts forward the concept of the Streaming Media system, and analyzes the component of the Streaming Media system and realization principle. Then it introduces the CDN technology, including the emergence and developing status of CDN, the working principle and network structure of CDN, and analyzes the three key techniques in the Streaming Media system, the content storage, distribution and routing technology, and compares with the C/S mode. To the next, the thesis brings forward the realization algorithms respectively. Finally, it establishes the MediaSwitch Streaming Media system platform, the keystones of which are the framework and interface design standard.The main tasks of the thesis are as follows:1. Research the CDN technology and the component and work principle of the Streaming Media system;2. Research and realize the three key technology algorithms in the system of the Streaming Media system;3. Establish the MediaSwitch Streaming Media system platform, and design the framework and interface standard.The storage, transmission and router techniques of the media are applied to the MediaSwitch streaming media system. The practice results obtain the prospective design and usage requirements. The researches indicate that the design thought and implement methods the thesis describes are reasonable and feasible.
