The article includes "congestion avoidance" in the "slow start" mechanism when in fact it is a totally differnt phase. Slow start has also a deeper motivation than congestion control: it is an algorithm which introduces information in the network gradually and it is inspired from electrical networks. |

The article says:
- During the exponential growth phase, Slow-start works by increasing the TCP congestion window by one segment for each acknowledgement received.
Should it not be double the congestion window for each acknowledgement received?
No it should not say that because it does not double for each ACK. It increases 1 Segment Size for each ACK received. This results in an exponential increase:
Send 1 packet. Receive 1 ACK. Increase by 1 SS Send 2 packets. Receive 2 ACKS. Increase by 2 SS Send 4 packets. Receive 4 ACKS. Increase by 4 SS Send 8 Packets. Receive 8 ACKS. Increase by 8 SS and so on.
This is explained in RFC 2001. —Preceding unsigned comment added by 64.129.167.114 (talk) 16:12, 1 October 2007 (UTC)
Textual error?

Big error
The article includes "congestion avoidance" in the "slow start" mechanism when in fact it is a totally differnt phase. Slow start has also a deeper motivation than congestion control: it is an algorithm which introduces information in the network gradually and it is inspired from electrical networks.
