5. If you have enabled the baseline RTT test, go to RTT test to know the Baseline
RTT and Window size.
6. If you have enabled the window sweep test, go to Window sweep and check the
Connections, Theoretical throughput and Throughput for each transmission win-
dow.
7. Go to the Throughput test panel and check the Status, Window size, Connections,
Throughput, RTT, Efficiency and Buffer delay.
Table 7.12: RFC 6349 Results
Setting Description
Global status Displays the current global test status. It can be any of the
following:
• Aborted: The test is terminated by the user either by press-
ing the run button or through the auto-start / stop function.
• Testing TCP connection: A check procedure is running
between the client and the server with the purpose to ver-
ify end-to-end connectivity between the near and the far
end. Depending on the test method, these ends could be
two ports of the same test unit.
• In progress: The equipment is running any of the baseline
RTT, window sweep or throughput tests.
• Error connect: The unit fails to deliver TCP segments
between the transmission ends. This message is usually
displayed at the beginning of the test, when the TCP con-
nection is verified but it can also happen at a later stage.
• PASS / FAIL: Global result for the RFC 6349 test. The
Pass or Fail indication is displayed at the end of the test
depending on the result of comparing the TCP throughput,
efficiency and buffer delay with their thresholds.
Current test It either displays Idle if no test is running or an indication of the
test that is being executed at the moment (Round trip time,
Window sweep, Throughput).
Current test direction Provides information about which transmission direction is
currently under test (Upstream or Downstream). If no specific
test duration is being tested then it displays Idle.
Remaining Shows the estimated testing time based on the settings con-
figured before the beginning of the tests.
