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.
