TCP Congestion Avoidance
Congestion avoidance slows down the TCP transmission rate and possibly initiates slow start. Congestion avoidance assumes TCP retransmissions are due to congestion and not lost packets. Therefore, congestion avoidance goes into effect when retransmissions occur or if too many duplicated acknowledgments are received (TCP must send an acknowledgment for every out of order packet).
