Stream - Burst Traffic Shape Setup
,press 'Traffic Shape' and select Burst to
configure Burst traffic
With Burst traffic, traffic is transmitted at a variable rate.
Traffic is transmitted at Burst 1 Bandwidth rate (from 0.00% to 100.00%) for Burst 1
Duration seconds, then at Burst 2 Bandwidth rate (from 0.00% to 100.00%) for
Burst 2 Duration seconds.
Gigabit Ethernet has a minimum burst of 0.01%. This sequence is repeated for the
duration of the test.

0.01% to 100.00%
Ethernet traffic is expressed in
terms of the percentage of
bandwidth used.
At 100%, the gap between frames
is at its minimum. As the
percentage is reduced, the IPG is
increased.
Rate:
IPG
(ns)
is 12
bytes or 96 bit times.
The interpacket gap (IPG) is the
delay between successive frames.
Rate:
Bit
Rate
The bit rate, given as a number of
kbps, is a direct function of the
bandwidth percentage.
Because the frame length can be
random, there is no fixed
relationship between bit rate and
data rate.
Burst
Bandwidth
1/2
Enter the size of the burst the XTT
5000 will transmit.
Burst
Duration 1/2
Enter the number of seconds the
first or second burst of traffic will
last.
* When changing units from Percentage to IPG to Bit Rate, the display will reset back
to the last value entered for those units.
Burst Bandwidth Accuracy
The accuracy of the burst bandwidth is reduced when the burst duration is shorter
than the time to send approximately 100 frames at 100% bandwidth. The minimum
recommended durations follow:
Burst Size
Duration
64 bytes
0.0051 ms
1519 bytes
0.0121 ms
4096 bytes
0.3278 ms
12000 bytes
0.9600 ms
