iGridMedia: Providing Delay-Guaranteed Peer-to-Peer Live Streaming Service on Internet
Almost all existing Peer-To-Peer (P2P) streaming systems can only provide non-interactive service on Internet. In this paper, the authors focus on providing delay-guaranteed service to support delay-tolerant interactive applications (such as online auction, person interview, video sharing & commenting, etc.) using P2P streaming technology. In an interactive channel, all or part of the participants can interact with the presenter or publisher at the source. Unlike existing P2P streaming service, there is different level of delay and synchronization requirement in the interactive applications, meanwhile, the participant number in each channel is relatively small but the concurrent channel number is large.
