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.
Line rate can only limit the total traffic rate on a physical port, while traffic policing can limit the rate of a
flow on a port. To limit the rate of all the packets on a port, using line rate is easier.
