Hello! > Subject: Re: Sender-side SWS avoidance in tcp_sendmsg() Actually, this thing has nothing to do with SWS avoidance. It is workaround for a bug, noticed in win2000/XP?, when overoptimized TCP receiver in http client delivers data only when it sees a PSH. Normally, TCP may send the whole multigigabyte stream of data not doing even single PSH because it always has more data to transmit. So, forced_push() means that we make at least one PSH per window, not depending on any other things sort of "amount of queued data". Yes, this means that skb1 is marked to carry PSH and the next PSH must happen not later than Y+(tp->max_window>>1).
