Description
RFC 2544 defines four main test types. You can configure and perform a test for a certain service, such as IPv4 or Ethernet, and analyze the results of the test to examine the various SLA parameters of the service. The test packets traverse through the same path as the regular service traffic. These tests are repeated for different frame sizes before calculating the measurement. (For example: 64, 128, 256, 512, 1024, 1280 and 1518 bytes.)
Configure the type of RFC 2544-based benchmarking test to be performed. Because of the ability of these tests to measure throughput, bursty frames, frame loss, and latency, this mechanism is also used to diagnose and examine Ethernet-based networks.
Options
throughput |
Measure the maximum rate at which none of the offered or transmitted frames are dropped by the device on which the test is performed. You use this test to measure the rate of successful transmission against the theoretical rate of the Ethernet media used for testing. |
latency |
Measure the time interval between the arrival of the last bit of the input frame at the input port and the output of the first bit of the frame on the output port. The test is repeated 20 times and the average latency is recorded as the measure for the frame size under test. |
frame-loss |
Measure the percentage of frames that must have been forwarded by a
network device under steady state (constant) load conditions, but were
not forwarded due to lack of resources.
The
test is repeated for the maximum rate of the Ethernet media (100%) and
further lower granular rates by steps, which are configurable with the
|
back-back-frames
(Junos OS) or back-to-back (Junos OS
Evolved) |
Measure the number of frames that are forwarded by the device on which the test is performed when a burst of frames with minimum inter-frame gaps is sent to that device from another source device. The minimum burst length must be at least 2 seconds. If the transmitted frames are equal to the frame count of the burst, then the test is repeated by increasing the number of frames in the burst. The back to back value is then determined as the frame count with the maximum burst size transmitted by the device under test with no loss. |
