摘要: 传统高带宽拥塞控制算法不适用于小缓存高速网络。针对该问题提出端算法与中间节点结合的拥塞控制算法,根据缓存区占用大小调整调节因子a、保障因子c,自适应增加或减少窗口大小。实验结果表明,该算法可以在小缓存高速网络中实现高带宽利用率、快速收敛和不同RTT流的公平性。

Abstract: Traditional congestion control algorithm is inapplicable for small buffer high speed networks. Aiming at this problem, this paper proposes a congestion control algorithm combining the end-to-end and middle-node together. This algorithm adjusts the window size self- adaptively by changing the values of adjustment factor a and protection factor c. Experimental results show that in small buffer high speed networks, this algorithm can realize high bandwidth utilization, high convergence speed and fairness of different RTT flow.

Key words: congestion control, small buffer, high speed networks, fairness, convergence
