Configuring Traffic Policing; Configuration Procedure - H3C S5820X Series Configuration Manual

enough tokens in the token bucket, packets can be forwarded. Otherwise, packets are put into QoS
queues for congestion management. Thus, the traffic passing the physical interface is controlled.
Figure 5-4 Line rate implementation
In the token bucket approach to traffic control, bursty traffic can be transmitted so long as enough
tokens are available in the token bucket; if tokens are inadequate, packets cannot be transmitted until
the required number of tokens are generated in the token bucket. Thus, traffic rate is restricted to the
rate for generating tokens, thus limiting traffic rate and allowing bursty traffic.
Compared with traffic policing, line rate can only limit traffic rate on a physical interface. To limit the rate
of all the packets on interfaces, using line rate is easier.
