Transmitting a
bursty load
With a bursty load, the unit transmits frames at up to 100%
bandwidth for a specific time interval, followed by no frame
transmissions for a specific time interval. See Figure 22.
When you configure bursty traffic, you can specify the burst
bandwidth as a percentage of the duty cycle, or by specifying
the burst gap interval. If you specify the burst bandwidth as a
percentage of the duty cycle, and then specify the number of
frames per burst, the unit automatically calculates the burst
gap for you.
To transmit a bursty load of traffic
1 If you haven’t already done so, launch your application
(see “Launching an application” on page 28), and then
select your test (see the appropriate procedure below):
– “Selecting a layer 2 test” on page 46
– “Selecting a layer 3 IP test” on page 120
– “Selecting a layer 4 TCP/UDP test” on page 165
2 Press the Configure navigation key.
A configuration menu appears.
3 Use the left and right arrow keys to go to the Traffic
configuration menu.
