Push traffic toward a link's capacity and the waiting doesn't grow gently — it explodes. This simulator plots the classic delay curve, 1/(1−ρ), and animates the growing queue as you raise the offered load. You'll see why a link is never safely run at full capacity and why congestion is the failure mode of the statistical multiplexing that makes packet switching efficient — the closing lesson of the NET DIVE series.
