We have Smartbits test gear...great stuff, but the fact is that you really don't "know" how something will perform until you put it on real circuits and connect it up to real gear. You can get a very good idea, particularly if you know how to test, but there is always an element of uncertainty.

You can decide on the size of the packets, layer 4, direction and even bandwidth so I'd say it's very possible to set-up a test environment that isn't too far of real world.

Good question. But the problem there is creating a real world test environment. Convergence, can be tested somewhat accurately in low network utilization situations. To adequately test Jitter/Delay you really need to load the network, as that is when the jitter and sparatic latency happens.
