The output is in comma separated value format and is exported to Excel (one file for IPv4, one for IPv6) where it is analyzed to look at the histograms of AverageAvg(ping_-rtt) and AverageAvg(nping_-rtt) etc. The script was run from a host (pinger.slac.stanford.edu) located st at SLAC in Northern California in the San Francisco Bay Area. It was run multiple times to ensure the behaviour was not dependent on time of day or day of week etc. To ensure the selected target hosts were not unique in some respect we also obtained a list of target hosts from the perfSONAR project , and repeated the analysis for them. Finally, to ensure there was not something unique about making the measurements from SLAC, we repeated the measurements to the same sets of targets from MAs in China, Malaysia, and Thailand.
