No, but only if you use circuits. But then you've pushed the 
"congestion" overload situation to the circuit setup time, and not all 
circuits will succeed.

Or you could be omniscient ;-)

Otherwise, you need to deal with the fact that sometimes two packets 
want to go to the same output port and can't, and you didn't find that 
out until they collided.
