99..33 PerformancePerformance
The FC Performance test is one of the methods to evaluate the network quality and
defines many tests to determine the performance characteristics of the network
device or entire network. Network Master includes several physical setups (test
modes) and five different tests.
Throughput Test
The throughput is the maximum rate at which a DUT (Device Under Test) can
forward frames without frame loss for a specific frame size. That is, the
maximum rate at which the number of test frames sent by the DUT is equal to
the number of test frames sent to it by the test equipment.
Traffic Profile Test
Traffic Profile Test measures actual throughput with varying the line load in up
to ten steps. For each selected frame size, a set of throughput steps defined by
user will run and actual measured throughput will be recorded.
Latency Test
Latency Test is the delay time from sending the frame from Network Master to
returning the frame to Network Master. This test measures the latency when
frames are sent at maximum throughput measured in Throughput Test. The
latency dispersion is measured as jitter.
To run this test, it is required to perform Throughput Test at the same time.
Burst Test
Burst Test measures the number of frames in the longest burst that the DUT
will handle without the loss of any frames.
Credit Test
Credit Test measures the minimum credit value that can output the maximum
throughput measured in Throughput Test.
To run this test, it is required to perform Throughput Test at the same time.
99..33..11 Ports Setup and StatusPorts Setup and Status
The first step to run an application is to set the port interfaces. Set the port
interfaces in the Ports SetupPorts Setup screen, which also provides the port status
information.
The setup options and status information related to the Fibre Channel interface
are described in the following section:
FC Setup and Status
For applications also including an OTN interface, refer to the setup options and
status information for OTN in the following section:
OTN Setup and Status
Refer to the sections corresponding to the required port setup.
