The sending computer transmits a pack, waits for a signal from the recipient that acknowledges its safe arrival, and then sends the next packet," New Scientist magazine said on Wednesday.

Wrong! TCP sends packets in advance, times the return ack, and learns the sending rate required to maximize throughput of the channel. It can have many packets in transit before their acks start to arrive.

When the researchers tested 10 Fast TCP systems together it boosted the speed to more than 6,000 times the capacity of the ordinary broadband links.

Bull! TCP will fill a channel to about 80% of its maximum capacity.
