Fair TCP Window-based Control in Single Congested Network with Explicit Congestion Notification

TCP 단일 혼잡 망에서의 ECN을 이용한 공정한 윈도우 제어

In this paper, we propose a window-based congestion control algorithm to achieve a fair sharing of the available bandwidth in ECN capable heterogeneous TCP networks with a single bottleneck link. The proposed algorithm is based on extracting the network status from the successive binary congestion information provided by ECN. From the explicit network information, we estimate the fair window size proportional to the propagation delay. Through simulations, the effect and performance of the proposed algorithm are shown for the heterogeneous networks.
