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。
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.
