Rately: Accurate Data Center CC based on One-Way Delay
Guannan Zhang, Dinghuang Hu, Dezun Dong · 2023
Delay-based congestion control (CC) protocols have been widely used in data centers, where senders monitor the real-time delay and adjust the sending rate or congestion window accordingly. We propose Rately, a CC algorithm that utilizes accurate one-way delay (OWD) measurements and a compatible rate regulation mechanism. Experiments show that Rately greatly improves performance under realistic workload.
