Webthose with shorter RTTs. This is because when BBR becomes cwnd-limited, it places twice the BDP (Bandwidth Delay Product) amount of packets in flight. We summarize these findings in Observation 4. Observation 4. When two BBR flows compete at a bottleneck, the flow with a longer RTT will get higher bandwidth than the flow with a shorter RTT. Webbounded by 1 second . Moreover, while its cwnd may grow up to the maximum storable number, data transmission is limited by the Receiver Window (rwnd). This means that flow control will save TCP from failing. From this, we can learn two simple rules: lower-bound any values calculated from the RTT (and,
