  • Slow Start (SS) & Additive Increase (AI) (AI=Congestion Avoidance)
    • start with the congestion window (cwnd) = max segment size
    • for each successfully received ACK increase the cwnd size by 1 until the cwnd = threshold value; (exponential increase)

Subsequently, for each successfully received ACK, increase the window size by 1/n segments up to a size of the receiver window. n=current congestion window (cwnd) size.
