No, you need to set things on both sides. The sender has to buffer data until it is ACKed in case it needs to retransmit. So, its buffer needs to be as big as the advertised window or the sender buffer will effectivly limit the advertised window. allman -- Mark Allman -- NASA GRC/BBN -- http://roland.grc.nasa.gov/~mallman/
