Assessing the Impact of Signaling on the QoE of Push-Based P2P-TV Diffusion Algorithms

Internet video and Peer-To-Peer TeleVision (P2P-TV) are attracting more and more users: chances are that P2P-TV is going to be the next Internet killer application. In recent years, valuable effort has been devoted to the problems of chunk-scheduling and overlay management in P2P-TV systems. However, many interesting P2P-TV proposals have been evaluated in an idealistic environment: in this paper, the authors instead study them by taking special care in defining realistic conditions for their evaluation. In particular they analyze the impact that signaling errors can have on a push-based P2P-TV overlay by means of simulation.
