Following adds this technology to your private workspace so related learning is easier to organise and revisit.
What is TCP BBR?
TCP BBR is a congestion-control algorithm that estimates available bottleneck bandwidth and round-trip propagation time. This profile connects the concept to KBY's practical engineering guidance.
Unlike primarily loss-driven algorithms, BBR builds a model of the network path and paces traffic around its estimated operating point. Kernel version, queueing, fairness with other flows and path characteristics influence whether it improves throughput and latency.
Control TCP sending rates using a model of path bandwidth and delay.
- Optimizing high-latency connections
- Improving CDN throughput
- Reducing bufferbloat
