Policing and CAR do not give any type of minimum traffic
guarantee. They do the opposite, which is to define a maximum
allotment. When this allotment is exceeded the specified exceed and/or
violate actions are performed. This does not meant that while traffic
is "conforming" it still cannot be dropped. It simply means that it
won't be dropped by the policer, but if the queue is full it will be
dropped or denied admission into the queue altogether.
