How to use the Burst Mode for Ethernet Traffic Generation
What is Burst Mode?
Burst mode is a feature that is commonly used to simulate "bursty" traffic loads on a
network device.
This mode is used as a more realistic method of testing network loads than a constant
bandwidth, because Ethernet traffic is typically "bursty" by nature.
Configuration Settings (from the

Rate: From this menu select either Constant %Bandwidth or Constant
Mbit/sec.
For Burst mode, burst of 100% BW are inserted, but the overall rate is
averaged over time.
•
Burst Size: The number of packets within the generated burst, with the Minimum
Inter-Packet Gap (IPG) allowed, between each packet.
This is sometimes referred to as the Burst Width.
Configuration Notes:

The maximum Burst Size allowed is equivalent to the maximum Frame Rate, in
Packet Per Second (PPS).
Before adjusting the Burst Size the user should change the test stream's Frame
