Forwards a mixed bag of small and large packets from tens of thousands  
of streams (not random)

1. at sub-millisecond latency
2. no packet loss at full line rate on multiple ports
3. deals appropriately with multiple ports at full line rate leading  
to a single port

And finally, is responsive to operator control even when full line  
rate is directed at switch itself.

Note the "not random" comment.  People love to use the random feature  
of ixia/etc but it rarely displays actual performance in a production  
network.
