6.9 RFC 2544
The RFC 2544 is a benchmarking methodology and defines a number of tests to
be used for describing the performance characteristics of a network device (or
a complete network). The Network Master includes several physical setups
(test modes) and four different tests.
Throughput Test
The throughput is the fastest rate at which a DUT (Device Under Test)
can forward frames without frame loss for a specific frame size. That is,
the fastest rate at which the count of test frames transmitted by the DUT
is equal to the number of test frames sent to it by the test equipment.
Frame Loss Test
Used to determine the frame loss rate of a DUT throughout the entire
range of input data rates and frame sizes.
Latency Test
Used to determine the duration from when the frame left the unit to when
the frame returned to the unit. The test is done for different line loads for
a specific frame size.
Burst Test
This is also called burstability or back-to-back test. The burst value is the
number of frames in the longest burst that the DUT will handle without the
loss of any frames.
If your test parameters are identical for the throughput and the frame loss test,
use the combined test 'Throughput and Frame loss' to save time and enhance
overview at the results pages.
6.9.1 Ports Setup and Status
The first step in running an application is to set up the port interfaces. This is
done on the Ports Setup screen, which also provides port status
information.
The setup options and status information related to the Ethernet interface are
described in a separate section:
Ethernet Setup and Status
For applications also including an OTN interface, you can find a description
of the setup options and status information for OTN in the following section:
OTN Setup and Status
Please refer to the sections relevant for your current port setup
requirements.
6.9.2 Test Setup
6.9.2.1 Control
When you go to the test setup of the RFC 2544 application, the following
screen is displayed.
