TCP congestion control algorithms determine how fast data flows across networks. BBR (Bottleneck Bandwidth and Round-trip propagation time) takes a model-based approach, estimating the true bottleneck bandwidth rather than reacting to packet loss.

For high-throughput servers, enabling BBR alongside the fq scheduler consistently improves throughput and reduces bufferbloat under load.
