：BQL 拥塞控制旨在充分利用可用的瓶颈带宽，同时将瓶颈缓冲区队列负载保持在较低水平，以防止其产生可避免的额外延迟或延迟抖动。在本文中，提出了基于延迟的拥塞控制研究的中间结果。使用 RMDT 协议，我们评估了其在高带宽延迟产品网络条件下的性能，并使用 iperf 实用程序将其与 TCP BBR 进行了比较。在大范围的延迟/带宽/丢失条件下已经达到了高瓶颈带宽利用率。在某些情况下，BBR 的一些性能问题也得到了观察和调查。
: BQL congestion control is aimed to utilize full available bottleneck bandwidth while keeping bottleneck buffer queue load on some low level to prevent it from producing avoidable additional delays or delay jitter. In this paper, an intermediate result of research in delay-based congestion control is presented. Using RMDT protocol we have evaluated its performance under high bandwidth delay product network conditions and compared it with TCP BBR using the iperf utility. High bottleneck bandwidth utilization in a wide area of delay/bandwidth/loss conditions have been reached. Some performance issues of BBR in some cases has also been observed and investigated.
