Webb23 aug. 2024 · This first phase is typically called a “slow start”. Upon detection of packet loss, TCP reduces the send rate, and (after a while) starts to increase the send rate again, albeit in (much) smaller increments. This reduce-then-grow logic is repeated for every packet loss afterwards.
