I am more interested in getting an "Available Bandwidth" estimator. Due to this available bandwidth, I am interested in congestion window. As whenever congestion window goes to half it means the data rate has gone to its upper limit. I want to use this particular property of congestion window to ca

I used a passive TCP RTT calculator and TCP re-trans monitor to guess the conditions to a host or group of hosts with some success. I the. Derived the network "weather" from this and it worked pretty well to dynamically tune DPI box policing for wireless networks. It also makes cool graphs. Esp
