Help text

BBR (Bottleneck Bandwidth and RTT) TCP congestion control aims to maximize network utilization and minimize queues. It builds an explicit model of the bottleneck delivery rate and path round-trip propagation delay. It tolerates packet loss and delay unrelated to congestion. It can operate over LAN, WAN, cellular, wifi, or cable modem links. It can coexist with flows that use loss-based congestion control, and can operate with shallow buffers, deep buffers, bufferbloat, policers, or AQM schemes that do not provide a delay signal. It requires the fq ("Fair Queue") pacing packet scheduler.
