Paper Abstract
"Researchers and practitioners have proposed various transpo= rt protocols to keep up with advances in networks and the applications that= use them. Current Wide Area Network protocols strive to identify a congest= ion signal to make distributed but fair judgments. However, existing conges= tion signals such as RTT and packet loss can only be observed after congest= ion occurs. We therefore propose Elastic Transmission Control (ETC). ETC ex= ploits the instantaneous receipt rate of N consecutive packets as the conge= stion signal. We refer to this as the pulling rate, as we posit that the re= ceipt rate can be used to =E2=80=9Cpull=E2=80=9D the sending rate towards a= fair share of the capacity. Naturally, this signal can be measured prior t= o congestion, as senders can access it immediately after the acknowledgment= of the first N packets. Exploiting the pulling rate measurements, ETC calc= ulates the optimal rate update steps following a simple elastic principle: = the further away from the pulling rate, the faster the sending rate increas= es. We conduct extensive experiments using both simulated and real networks= . Our results show that ETC outperforms the state-of-the-art protocols in t= erms of both throughput (15% higher than Copa) and latency (20% lower than = BBR). Besides, ETC shows superiority in convergence speed and fairness, wit= h a 10=C3=97 im-provement in convergence time even compared to the protocol= with the best convergence performance."
