TCP-polite rate control based on cooperative measurement

Based on the cooperative measurement of new congestion metric instead of drop ratio and round-trip time, a new cooperative transmission control mechanism, called TCP-polite rate control TPRC, is proposed. In this scheme, the congestion metric of network is obtained with cooperative measurement and feeds back to rate-based pacing mechanism, thus keeping the transmission rate at the lower bound of available bandwidth. Simulation results show that TPRC scheme outperforms TCP and TCP-friendly rate control protocol in terms of fast-start, efficiency, and fairness. Copyright © 2013 John Wiley & Sons, Ltd.
