dt,
Cisco considers CAR to be legacy, is not developing new features for it, and
discourages its use. As far as functionality goes, class-based policing
allows more extensive match criteria, including NBAR, CoS, and RTP port
numbers. The major difference appears to be support for RFC 2697 and 2698,
which add the Violate action and the Peak Information Rate. You can find a
detailed comparison of the two at the following link:
