For example, in
Figure 4-4
, Switch A sends packets to Switch B. Switch B performs traffic policing on
packets from Switch A and drops packets exceeding the limit.

GTS application
You can perform traffic shaping for the packets on the outgoing interface of Switch A to avoid
unnecessary packet loss. Packets exceeding the limit are cached in Switch A. Once resources are
released, traffic shaping takes out the cached packets and sends them out. In this way, all the traffic
sent to Switch B conforms to the traffic specification defined in Switch B.
