1. Explicit congestion notification is proposed as the congestion avoidance policy. 2. Networks use congestion control and congestion avoidance techniques to try to avoid collapse. 3. Congestion avoidance can be achieved efficiently by reducing traffic.4. As a result, there are a number of TCP congestion avoidance algorithm variations. 5. When this sequence number is acknowledged, TCP returns to the congestion avoidance state. 6. This is more generally referred to as congestion control and / or network congestion avoidance . 7. The ARQ protocol also provides flow control, which may be combined with congestion avoidance . 8. Modern networks use congestion control and congestion avoidance techniques to try to avoid congestion collapse. 9. By design, the TCP congestion avoidance algorithm will rapidly fill up the bottleneck on the route. 10. Before slow-start was introduced in TCP, the initial pre-congestion avoidance phase was even faster.
