They both fall under the same concept. If there is no congestion on the
line, technically you are under a FIFO policy. You don't queue ANYTHING
until there is some sort of congestion to get to the line.
Think about going to the amusement park. They have all these bizarre
line contraptions set up, but if you're there really early in the
morning, do you use them? No, you go straight onto the ride. The
contraptions are still configured, but are not used until there is some
congestion.
CBWFQ or custom-queuing will depend on the wording of the question for
bandwidth used. Remember that CBWFQ defaults to allocating only 75% of
the line's bandwidth. (Change with the "max-reserved-bandwidth 100"
command) But otherwise, the concept is still the same. And with CAR,
you're setting caps of traffic, but until you meet them, there's nothing
going on.

my friend
CB-WFQ will not do the trick
i though the same thing a while back ...here is the scoop on CB-WFQ.
this method will only gurantee the allocated bandwithd during congestion
.
now the question says ..
dived traffic exactly .....then CB-WFQ will not do the trick..
try custom queeing ..or CAR
