ABSTRACT

Currently, service providers are facing with problem is slash dot effect or flash crowds when many users increase significantly and at the same time access into one live event. Now to address these issues, the combined benefits of P2P CDN CDN P2P hybrid system is being used, but the server's processing ability of a hybrid P2P CDN system has reached the critical point and the majority of users are constantly want to receive better quality content. Accordingly, the service provider has to spend money to add servers continuously. Peer-to-Peer network is one of a solution to solve this problem. To decrease request data to the server, users can request data from other users in the same network to get the desired content. In this paper, we propose the efficient data exchange protocol for P2P live video streaming over the Web in order to decrease the number of requests to servers that means reduce the cost of transmission. Also by set up short timeout for request to server and split video into small chunk, our system has smaller end-to-end delay than unconnected mesh system in CDN-P2P-hybrid. In our setup environment, we compared the experiment the number of requests for change in delay between the server and the termination of the proposed method and the conventional method.
