The production of peer-to-peer video-streaming networks
Dafu Lou, Yongyi Mao, Tet Hin Yeap · 2007
We introduce the notions of production and saturation time for peer-to-peer real-time video-streaming networks. Due to the fact that video-streaming is divided into small blocks to transmit, production, adopted from economics, is defined as the number of users that have obtained video block m by time t. Saturation time refers to the time when the system leaves the state where there have been more users requesting block m than the number of users that the system could have supplied. Based on those two notions, we provide a lower bound on the achievable production functions. Simulation results are provided for a heuristic protocol which appears to confirm the lower bound in terms of production and saturation time. The analysis results have also been confirmed by simulation using a stochastic model.
