PingER Metrics Motion Chart

Internet Performance from EDU.SLAC.STANFORD.N3 to region=South Asia, measured by PingER between 09Jan03 and 08Dec14

Miscellaneous:

Tool: The interactive graph was generated using the Google Motion Chart Widget.
Data: The data presented here was collected by the PingER project, processed by prmout. The same data is available in tabular format.
- The statistics of Population were acquired from the U.S. Census Bureau,
- The country to region mapping was obtained by the geographical database maintained by the PingER project.
- The Internet usage statistics were taken from Internet World Stats.
- The Corruption Perceptions Index (CPI) compiled by Transparency International were extracted from Wikipedia.
- The Digital Opportunity Index (DOI) is obtained from the ITU's ICT Statistics,
- The Human Development Index (HDI) is obtained from the UNDP Human Development Reports.
Please note that while all the PingER statistics were acquired over several years (i.e. since 1998), the other statistics were documented in Nov. 2007.
Intensity Maps: The same data may be viewed in the form of Intensity Maps.
Loading: The time to load and render the web page is largely determined speed of the link, the file length (about a MByte that is determined by the number of metrics and frequency of data points and the number of metrics) and the speed of the client rendering.
Metrics: Average RTT (ms), Normalized Throughput (Kbps), Population (#), Internet Users (#), Internet Penetration (%), Minimum RTT (ms), Packet Loss (%), Unreachability (%), Jitter (ms), DOI Index, HDI Index, CPI Index,

Usage:
By default, this page shows a motion scatter/bubble plot of the ping (100 Byte) average RTT in msec. (x) versus the normalized derived TCP throughput in kbits/sec (y). Each bubble represents a country. By default the bubbles are colored by region and their sizes are proportional to the Internet users. The motion is the time. The time granularity is by year. Click on the play button to initiate the motion.

To change the metric represented by the size of the bubble use the 'size' combo box to the right of the chart.
Click on the pull down box of an axis' label to change the metric that is displayed on an axis or in a table. Other PingER metrics that are available include minimum RTT, jitter and unreachability.
Move the mouse over a bubble to identify the values for the bubble.
Moving the mouse over an axis to choose either linear or logarithmic axis scaling.
Move the mouse over a colored legend symbol to blink the ballons asociated with the symbol's color.
To follow the changes in detail simply move the slider bar with the mouse.
One can select a bubble by clicking on it to provide a label for the bubble that persists with the motion. The trails check box leaves a trail to follow the motion of selected bubbles. N.b. selected bubbles determine how far the data to be displayed goes back in time.
By selecting different options from the combo-boxes on the left-top of the page, one may select the vantage point, the observed region and the granularity of the measurements.

Observations:

Ideally one wants low RTT, loss, jitter & unreachability and high throughput.
Note that with time there are an increasing number of bubbles as the monitoring extends to more countries.
Note, with time, the increasing focus on Africa (blue bubbles), and the fact that in general Africa has the highest losses, the highest average RTT and lowest throughput.
