:Floyd提出的随机提前检测(RandomEarlyDetection,RED)算法是拥塞控制领域中一种有效的分组丢弃机制,在模拟实验和实际监测中都取得了良好的效果.但它使用了具有抖动问题的4.3BSDTCP的窗口调整算法.另一方面,Mitra通过渐近线结果所得出的最佳窗口设计方程可以改善窗口抖动问题,但其通过平均往返时间调整窗口大小,与一般TCP窗口调整算法不同.文中以Mitra的渐近线结果为基础,推导基于排队长度的最佳窗口设计算法,并在此基础上提出了基于最佳窗口的设计RED算法.模拟结果表明,基于最佳窗口设计的RED算法可结合RED与最佳窗口设计机制的优点,其平均排队长度和排队长度抖动性能均优于Floyd的RED算法,可有效地进行网络拥塞控制
: Floyd’s Random Early Detection (RED) algorithm is an effective packet discard mechanism in the field of congestion control and has achieved good results in both simulation and actual monitoring, but it uses a 4.3BSDTCP with jitter On the other hand, Mitra can improve the window jitter by using the best window design equation derived from the asymptotic results, but it is different from the general TCP window adjustment algorithm by adjusting the average round-trip time.Taking Mitra Based on the asymptotic results, the optimal window design algorithm based on the queue length is derived, and based on this, a design RED algorithm based on the optimal window is proposed.The simulation results show that the RED algorithm based on the optimal window design can be combined with RED And the best window design mechanism, the average queue length and queue length jitter performance are better than Floyd’s RED algorithm, which can effectively network congestion control
