30 RFC 2544. Measurements
•
State — state of the testing process. Possible states:
– in progress — active state, frames sending and reception are
being executed;
– suspended — tests or test iterations are paused, frames are not
sent or received;
– completed — testing is completed automatically or is inter-
rupted by user.
•
Frame — sent frames size.
•
Load — current load on a link.
•
Tx — frames sending process display for each test iteration.
• Rx — frames receiving process display for each test iteration.
3. Right (main) window region ( Plot, Table, Details , F3, F4 and F5
functional keys correspondingly) — measurement results. For each test,
obtained results are displayed in three ways: graphical, table and tex-
tual. To switch between results display modes, just navigate to corre-
sponding tab.
4. Lower part of the window is occupied by toolbar with three buttons
(refer to Figure 5.2).
• Start/Abort — start and stop testing process (corresponds to
F6 functional key). To stop the testing process, press the Abort
button. In case the testing process is not aborted, system will
automatically stop its execution after all necessary measurements
are completed.
• Save — save obtained results as a file (corresponds to F7 functional
key Save ), for more details refer to Par. 5.5.1, page 40;
Note: if current measurements results were not saved,
with next start these data will be erased. On application
closing, unsaved data will be also lost.
•
Load — loading of previously saved measurements, for more de-
tails refer to Par. 5.5.2, page 41;
Measurement results for each test are presented at three tabs:
•
Plot — graphical representation of measurement results;
•
Table — tabular representation of measurement results.
•
Details — measurements log (this tab has the most detailed infor-
mation about executed test, this is important for troubleshooting of
equipment under testing).
Figure 5.2 shows an example of Details tab for Throughput test.
