A typical application of traffic policing is to supervise the specification of certain traffic entering a
network and limit it within a reasonable range, or to "discipline" the extra traffic. In this way, the network
resources and the interests of the carrier are protected. For example, you can limit bandwidth
consumption of HTTP packets to less than 50% of the total. If the traffic of a certain session exceeds the
limit, traffic policing can drop the exceeding packets.
Traffic policing is widely used for traffic entering the network of Internet service providers (ISPs). It can
classify the policed traffic and perform pre-defined policing actions based on different evaluation results,
for example, forwarding the packets evaluated as "conforming", and dropping the packets evaluated as
"excess".
