Graphical
presentation
The results of the performed RFC 6349 tests can be presented in either
tabular form or as graphical representations. The graphical presentation
mode provides an overview of the results and the progress of the test.
6.10.3.1 Summary
When you go to the test results of the Ethernet RFC 6349 application, the
following screen is displayed.
This screen presents the summary of current measurement values.
Local -> Remote: Shows the results of Upstream (Local to Remote)
test.
Remote -> Local: Shows the results of Downstream (Remote to Local)
test.
The measurement results are displayed in white cells.
Throughput and RTT
Window Size: The window size used for the step.
Connections: The number of TCP connections.
Threshold: The threshold of the throughput.
Avg Throughput: The average value of measured Throughputs.
Avg RTT: The average value of measured RTT.
Network Parameters
MTU / MSS: Maximum Transmission Unit / Maximum Segment Size
RTT: Round Trip Time
CIR: Committed Information Rate
