Bottleneck Bandwidth and Round-trip time (BBR)

Bottleneck Bandwidth and Round-trip time (BBR) is a network congestion control algorithm that optimizes data transfer. It estimates the maximum speed of the network’s narrowest point (bottleneck bandwidth) and the time it takes for data to travel back and forth (round-trip time). By using these estimates, BBR adjusts how data is sent to maximize speed while minimizing delays and packet loss. This approach helps ensure faster, smoother internet connections, especially over fluctuating or congested networks.
