RFC2544 Throughput Latency Home
Select RFC2544/NE Test as the test type on the Menu to perform RFC-2544 tests.
Set the Throughput/NE parameters, and the Latency parameters. Press to save
the configuration.
Throughput - NE
Parameter Options Details
Duration TIME
FRAMES
Set how measurements will be taken.
TIME: Base measurements on a length of time.
FRAMES: Base measurements on a number of
frames
Frames • N/A FE
• GigE

Duration = Frames
Time 4-60 seconds Duration = Time
Starting Rate .01-100% Set the rate at which frames will begin being
transmitted.
• 100% is a good starting rate for a standard
RFC test, recommended in RFC 2544.
• For NE testing, select the rate applicable to
your setup.
Stop Rate
(N/A
RFC2544
test)
01-100% Set the rate at which frames will stop being
transmitted. 100% is typical.
Resolution
(N/A NE Test)
01-100% Determine measurement precision.
• 1% is typical; you can go as precise as .01%
(very precise tests take longer to run).
• The search algorithm continues until the step
between two consecutive tests is lower than
this specified resolution.
Rate Step
Size *
(N/A
RFC2544
test)
01-100% Each step increases (or decreases) the traffic
rate by the specified amount. The NE Test tests
the throughput and/or latency at different test
rates and gives the result for each one.
*RFC2544 specifies a default resolution of 10%. This means if the true throughput
rate of the DUT was 98.5%, the test would report 90%. In some cases, higher
precision is required, hence the default for the test set is set to 1.0%.
Make sure to set the Starting and Stop Rates when configuring an NE test.
