<p>It's written to look like an academic paper, but it's pure

<p>As always with the coin-operated, the way to get them to change

Also, a lot depends on the TCP congestion control algorithm being used.
They are using NewReno which only researchers use in real life.
Even TCP Cubic has gone through several revisions. In my experience, the
NS-2 models don't correlate well to real world behavior.
In real world tests, TCP Cubic will consume any buffer it sees at a
congested link. Maybe that is what they mean by capture effect.
There is also a weird oscillation effect with multiple streams, where one
flow will take the buffer, then see a packet loss and back off, the
other flow will take over the buffer until it sees loss.
