Q82 / 100
What is TCP BBR (Bottleneck Bandwidth and Round-trip propagation time)?
Correct! Well done.
Incorrect.
The correct answer is B) A Google congestion control algorithm that models network conditions (bottleneck bandwidth and RTT) rather than using loss as a signal
B
Correct Answer
A Google congestion control algorithm that models network conditions (bottleneck bandwidth and RTT) rather than using loss as a signal
Explanation
BBR (2016) probes for bottleneck bandwidth and RTT, operating at Kleinrock's optimal point. It achieves 2700x higher throughput than CUBIC on lossy links and lower latency by avoiding buffer bloat.
