Do you mean the bursty traffic after there is a dropped segment? If there is
no dropped segment (including ACKs), TCP is as bursty as it is without window
scaling, sending 3 segments for every ACK (assuming delayed ACK for every 2
segments). I believe many implementations now have some simple form of
bursty control. And with SACK and various forms of NewReno, I think TCP is
not as busrty as it used to be when there is no window scaling.
