By combining these metrics, BBR calculates the optimal sending rate, ensuring that the network is utilized efficiently without causing congestion. A 1 Gbps server in New York talking
If the output is 3.10.0-... , your stock kernel lacks BBR. Proceed to Step 2. If the output is 3
In short, is a pre-compiled kernel module package that injects the BBR algorithm into Enterprise Linux distributions (EL7, EL8, EL9) that do not natively include it in their default kernels.
