Traffic Shaping - HPE 3100 v2 Series Configuration Manual

use of network resources by a certain application. For example, you can limit bandwidth for HTTP
packets to less than 50% of the total. If the traffic of a certain session exceeds the limit, traffic policing
can drop the packets or reset the IP precedence of the packets.
policing outbound traffic on an interface.
Figure 9 Traffic policing
Traffic policing is widely used in policing traffic entering the networks of internet service providers
(ISPs). It can classify the policed traffic and take pre-defined policing actions on each packet
depending on the evaluation result:
•
Forwarding the packet if the evaluation result is "conforming"
•
Dropping the packet if the evaluation result is "excess"
•
Forwarding the packet with its precedence, which can be 802.1p priority (available only for
green packets) and DSCP precedence, re-marked if the evaluation result is "conforming"

Traffic shaping

IMPORTANT:
• This feature is available only on the HPE 3100 v2 EI switches.
• Traffic shaping shapes the outbound traffic.
Traffic shaping limits the outbound traffic rate by buffering exceeding traffic. You can use traffic
shaping to adapt the traffic output rate on a device to the input traffic rate of its connected device to
avoid packet loss.
The difference between traffic policing and GTS is that packets to be dropped with traffic policing are
retained in a buffer or queue with GTS, as shown in
bucket, the buffered packets are sent at an even rate. Traffic shaping can result in additional delay
and traffic policing does not.
