66..99 RFC 2544RFC 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.
66..99..11 Ports Setup and StatusPorts Setup and Status
The first step in running an application is to set up the port interfaces. This is
done on the Ports SetupPorts 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.
