[Click] Testing RED

[Eddie Kohler]

Hi John,

So it'll depend on what you're trying to test.  The basic idea is simple -- 
just send a lot of packets into a queue that isn't draining that fast.  RED 
drops packets in this configuration for me:

RatedSource(RATE 1000) -> r::RED(10, 20, 0.2) -> Queue -> TimedSink(0.0005); 
r[1] -> Print -> Discard

(Dropped packets are printed.)  Note that this config doesn't have any kind of 
end-to-end feedback loop, like you'd see with TCP congestion control.

I was looking for an example where RED would actually drop packets.  Help would be appreciated.   You can send to jcstille at yahoo.com or I will be checking the mailing list.
