And I still have never seen anyone give me a packet capture of juniper
or cisco´s red
implementation.

I didn't know what RED was and had to look it up. For others new to the 
lingo:

A big issue is that "average queue length" was and is a terrible 
indicator of congestion. 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.
