But I think the first "bug" Van was referring to was the original RED "control law" - I asked him why he thought it would work as it really ends up looking like a step function which your first control theory course will show is rather primitive. The thing is, that TCP is really robust and almost anything will "work" on long-lived TCP connections. Which is what everyone used for testing.
