BBR (Bottleneck Bandwidth and Round-trip propagation time)

BBR (Bottleneck Bandwidth and Round-trip propagation time) is a network traffic control algorithm that optimizes data transfer speed. It estimates the best possible data flow by measuring the network's maximum capacity (bandwidth) and how long it takes for data to go round-trip (latency). BBR adjusts the rate of data sent to avoid overwhelming the network, ensuring faster and more stable connections. Instead of just waiting for buffers to fill, it actively gauges the network's true limits, leading to efficient, consistent performance, especially in high-speed or variable networks.
