Rethinking the rate estimation of BBR congestion control
Bo Su, Xianliang Jiang, Guang Jin, Haiming Chen · Electronics Letters · 2020
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.
