Suitable for high-latency, high-bandwidth network links.</li> <li>Reducing buffer occupancy on network links, thereby lowering latency. Suitable for users with slow access networks.</li> </ul> <p>I remember when BBR was first merged into the Linux 4.9 kernel in 2017, this congestion control algorithm proposed by Google was extremely popular in the tech community. At the time, I was doing cross-border file transfers on Linode, where packet loss was commonplace, so I wanted to test the results firsthand.</p>
