BBR (Bottleneck Bandwidth and RTT) is a new congestion control algorithm which is contributed to the Linux kernel TCP stack by Google. With BBR in place, a Linux server can get significantly increased throughput and reduced latency for connections. Besides, it’s easy to deploy BBR because this algorithm requires only updates on the sender side, not in the network or on the receiver side.
