If Token Bucket is used to control the traffics, when there are tokens in Token
Bucket, the packets can be sent in burst; if no tokens are available, packets will
not be sent until new tokens generate in the Token Bucket. Thus, the traffic of
packets is restricted under the generating rate of new token to achieve the goal of
restricting the traffics while allowing bursting traffic overpass.
Compared with TP, LR can restrict all packets via physical port. TP is realized at IP
layer implementing no function for packets that do not go through IP layer. If users
demand to limit the rate of all packets, LR is easier to be implemented.

The traffic-policing configuration is divided into two tasks: one is to define the
characters of the packets that need traffic policing; the other is to define the
policing policy.
