Figure 7 Traffic policing
Traffic policing is widely used in policing traffic entering the ISP networks. It can classify the policed traffic
and take predefined policing actions on each packet depending on the evaluation result as follows:
Forwarding the packet if the evaluation result is "conforming."
•
• Dropping the packet if the evaluation result is "excess."
Forwarding the packet with its precedence re-marked if the evaluation result is "conforming."
•
Priorities that can be re-marked include 802.1p priority, DSCP precedence, and local precedence.

GTS

GTS supports shaping the outbound traffic. GTS limits the outbound traffic rate by buffering exceeding
traffic. You can use GTS to adapt the traffic output rate on a device to the input traffic rate of its connected
device to avoid packet loss.
The differences between traffic policing and GTS are as follows:
Packets to be dropped with traffic policing are retained in a buffer or queue with GTS, as shown

rate.
• GTS can result in additional delay and traffic policing does not.
