Abstract

In fast long-distance networks, TCP fails to fully utilize the bandwidth due to its congestion control mechanism. A plethora of congestion control schemes that may enhance the performance of the transport protocol in fast long-distance networks have been proposed. The proposed schemes aim to satisfy three requirements of congestion control schemes: bandwidth scalability, TCP friendliness, and RTT fairness. However, due to the trade-off among these requirements, it is difficult to satisfy all the requirements simultaneously. In this paper, we propose a new window-based congestion control scheme called EIMD (Exponential Increase/Multiplicative Decrease) that increases congestion window size exponentially to quickly grap the unutilized bandwidth. We evaluate the performance of EIMD via computer simulations. The simulation results show that EIMD satisfies the three requirements. In addition, EIMD converges fast to the fair-share points.
