Distribution System Based On Peer-to-peer Download Build

With the rapid development of the microelectronics technology and the broadband technology, the Internet content becomes richer and richer. How to distribute the Internet content becomes a big problem. The traditional server/client distribution solution has great limitations. The server/client solution can work efficiently when the number of clients is not large. But it can't work well under when the number of clients is large. With the limitation of the server and the band resource, the distribution system based on the peer-to-peer solution can provide stability and high speed under all the conditions. It solves the distribution problem.Firstly, the present conditions of the Internet distribution system and the traditional solution are analyzed. Then, the traditional method is added to the peer-to-peer distribution system. The new system can meet the need of working efficiently under all conditions. Based on it, the architecture design and analysis for each subsystem (including the UDP Punching of the server side, the UPNP and the Kademlia of the client side and the database system) are established. The improvement of peer-to-peer communication solution is mainly analyzed. Additionally, the UPNP method and the Kademlia are discussed.
