RE: TCP Bandwidth Control (thrulay)

["Logg, Connie A." <cal --at-- SLAC.Stanford.EDU>]

I am retired now, but I have been running thrulay for a couple of years. I have some plots of thruput vs rtt and they can be very interesting. 
 
The 'master page' is http://www.slac.stanford.edu/comp/net/iepm-bw.slac.stanford.edu/slac_wan_bw_tests.html
 
As you scroll down through the graphs, click on 'scatterplots'. Here are a couple of examples:

You might consider looking at thrulay. It is the only tool I know of that tracks
RTT of the packets in the throughput test.
