Cdn Technology In The Application Of Streaming Media Platform

The rapid development of CDN (Content Distribution/Delivery Network) technology provides the best solution for the application of Media Streaming. This paper takes the entire province large-scale class Streaming Media platform CDN network optimization construction as a background, researches the key technology of CDN. This article unifies the practical example, points out some flaws of the traditional CDN solution, and proposes the solution. The content of the thesis is one of the hotspots in compute science domain recently and it has wide market space.This paper analyzes CDN network construction technology, and then puts forward more advanced model. It researches CDN content routing and proposes double level load balancing strategy. The implementation of the CDN relies on many kinds of technologies, and load balancing is most important. This paper discusses two algorithms which to achieve network proximity and analyzes severs' load before and after load balancing management to compare the performance. It also puts forward the idea about network tree and gives the algorithm about how to divide the network.Take the theoretical analysis and project background as the foundation, this paper analyzes many kinds of solution, and then designs and realizes up to ten thousand concurrent class CDN system with software.In the above foundation, this article focus on the future CDN system expansion and compatibility, carries on the theoretical analysis and proposed solution.
