Fundamentally, CAR is policing, whereas CBWFQ is, well, queuing. With
policing, there's no buffering--if you exceed the rate limit you're dropped.
Optimally, the sender should try to self-regulate when being policed,
otherwise the sender must expend overhead trying to recover from being
dropped.
Queuing attempts to arbitrate access to a limited resource when congestion
is occurring--making it fair if you will, spreading the wealth. Certain
traffic is buffered so that certain other traffic can be sent ahead of it,
based on whatever the arbitration mechanism is.
