The Research And Implement Of Video Network Architecture And The Key Technology Based On CDN

With the development of the computer and internet, great change happens on people's life habits and attitudes. It can supply us with infinite digital space, and it also gives itself infinite development.With the high request of computer network technologies, it's far for us to get the high access speed and the good quality of service(QoS). As a result, the CDN appears and its advantages take more and more important place in network technologies day after day.CDN's purpose is that with the help of the new layer added to the original internet architecture, CDN send the content to 'edge' of its nearest users, which can make users get the content. It can fully solve the problems due to the narrow network bandwidth, large numbers of visiting users, and so on, and improve the response speed of websites.This paper's content is the application and implement of video network architecture and the key technology based on CDN. This paper introduces the keystone about CDN, and mainly discusses the key technology about CDN, including load balancing technique and content distribution technique. What's more, analyze and study the Chinese internet environment, bring the goals of the video network architecture and layout it; Later, achieve the application of the load balancing technique and content delivery technique in the video network; At last, analyze the testing data and sum up.With the development of the Broad Band, the application about CDN technology must be one of the key applications in future.
