Ok, i did not notice the one you mention. Speaking of this one i notice that it is implemented in a somewhat strange way. ss_fltsz_local is set to TCP_MAXWIN (65535) and the assignment in tcp_input.c is then something like p->snd_cwnd = mss * ss_fltsz_local dimensionally, this looks to me like bytes^2 ... cheers luigi -----------------------------------+------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
