确认（ACK）压缩使得瓶颈带宽和往返传播时间（BBR）中的可用带宽估计不准确，从而导致在低分组丢失率环境下的高排队延迟。额外的排队延迟会影响像Skype这样的交互式应用程序的用户体验。为了解决上述问题，本文提出了一种新的方法，称为校准带宽估计（CBE），校准带宽估计。CBE能准确检测出不真实的ACK率，大量的仿真实验证明了CBE的有效性。
The acknowledgment (ACK) compression makes the available bandwidth estimation in bottleneck bandwidth and round-trip propagation time (BBR) inaccurate which results in the high queuing delay under low packet loss rate environments. The additional queuing delay affects the user experience of interactive applications like Skype. To solve the above-mentioned issue, this Letter presents a novel method, named calibrating bandwidth estimation (CBE), to calibrate the bandwidth estimation. The CBE can detect the implausible ACK rates accurately and the extensive simulation prove the effectiveness of CBE.
