The current TCP window is the minimum of the Sender Congestion Window (snd_cwnd) and the Receiver Advertised Window (rcv_wnd). The Linux getsockopt (TCP_INFO) call returns a “struct tcp_info”, which does include the snd_cwnd, but it doesn’t contain the rcv_wnd info. Any help is greatly appreciated!
