where is modified the congestion window after 3 dup ACKs are receibed?
I would like to modify the fast retransmit and fast recovery algorithms to set the slow start threshold(send_ssthresh) to 1/4 of the congestion window (send_cwnd) instead of 1/2 each time 3 dupacks are receibed.
I read that this is done in tcp_fastretrans_alert() and in tcp_cong_avoid() but I dont know exactly where or how it's done.
I am using the source code for 2.6.32 kernel
I hope that someone could help me with this, please.
