摘要： 为了解决校园网中应用的BBR(Bottleneck Bandwidth and Round-Trip Time)拥塞控制算法在STARTUP阶段由于未收到ACK(Acknowledge Character)而引起的时延振荡和空窗问题,提出了BBR单边适应算法。该算法只运行在发送端,不受网络协议和上层应用的限制。通过改善时延估计器的加权系数,设计时延瞬时平均偏差估计器,将估算结果作为时延估计器的振荡平滑因子,提高时延估计器应对时延剧烈抖动的能力。为了尽可能解决不可避免的空窗问题和序号回绕,在发送端设计了流量状态机和STARTUP状态机来维持较高的链路吞吐量。根据具体的传输情况将流量分为6种状态:new,blocked,wai-ting,time_waiting,running,terminated,并根据流量反馈将STARTUP阶段的传输性能分为3个状态:GOOD,NORMAL,BAD。实验结果表明,改进后的BBR比原有BBR算法在STARTUP阶段具有更好的传输性能,且优于目前主要应用的被动拥塞控制算法(Reno,CUBIC)。
