Abstract

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.
