torrent client traffic shaping question

torrent client traffic shaping question

[Brent Clark]

Hiya

I got this question to ask, and I was hoping the TCP/IP gurus would be 
able to help me understand this.

K you know how with traffic shapping you can control only the traffic 
leaving you, how it is that torrent clients say they can control the 
download as well as the upload. I would think the client can only 
control the upload.

TIA

If you read from socket at fixed rate, it's TCP receive buffer is emptied at 
same rate. TCP announces free buffer in receive window field, so congestion 
window on sender side is also adjusted, thus limiting send speed to the rate 
you read from socket on receiver side.
