WebbSlow-start algorithm is part of the congestion control in TCP, designed to avoid sending more data than the network is capable of transmitting. Slow-start algorithm works by increasing the TCP Window by one segment for each acknowledged segment. This behavior effectively doubles the TCP Window size each round trip of the network. WebbWhen congestion window size is greater than the threshold, slow start phrase ends. On phase two, congestion avoidance takes over. It'll increase congestion window linearly by one segment per round-trip-time. The congestion window stops increasing when TCP detects network congestion due to timeout or receipt of duplicate acknowledgement.

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.
