The Inbound Delays and Losses plots are intended to give a quick overview of the one-way delays and losses from other boxes to your box in near real time. They are not intended as a full analysis of the data collected with your box, such an analysis is available from the TTM website. The TTM website also allows you to access data sent from your box to other boxes as well as older data. The page
will automatically generate a list of all active test-boxes from which your
test-box currently receives measurement traffic. Select All boxes
to get plots for all test-boxes or select a subset. Select Delays
or Losses for delay and loss plots respectively.
The form
lets you select a time-interval and plot size. Delay
Plots: Data is plotted as a dark blue line, showing the average delay
plotted on top of a orange area. The orange area shows the minimum and maximum
delay during 30 minute intervals and thus gives an idea about the spread around the average. Times along the X-axis are UTC. Times along the Y-axis are in
milliseconds. The y-axis of the delay plots can be adjusted.
If the range is too small and the "auto-increment"
option is selected, then the y-range will be increased.
If the "fixed" option is set, points outside the range will drop off
the plot. Loss
Plots: Data can be plotted as Loss only and Loss and arrived.
In the first case, the percentage of packets lost during 15 minute intervals
are shown, in the latter cases, both the percentage of packets that arrived
and was lost are shown. Times along the X-axis are UTC. Press the reload
button of your browser to update the plots, but please keep in mind that the
data-base behind these plots is only updated once every 10 minutes. Also note
that it may take up to 12 hours before a newly installed test-box appears in
the list. On some browsers, you may have to do a forced reload instead of a
regular reload due to caching. Using the average
and minimum/maximum to describe the delays is not according to RFC2330.
However, they do give you a first indication of the incoming delays. For a
full analysis of the data, including the correct statistics, go to the
TTM Website
at the RIPE NCC. |
