Median RTT per country and US state
Mapping RTT by political boundaries can reveal where high latency issues are located.
Path Dispersion
The paths taken by different traces show where the majority of a monitor's traffic travels.
-
AS Path Dispersion (by AS Hop)
AS connectivity near monitor
-
AS Path Dispersion (by IP Hop)
AS connectivity near monitor (with IP hop distances preserved)
-
IP Path Dispersion (by IP Hop)
IP connectivity near monitor
RTTs vs. Distance
Comparing RTT with geographical distance helps show if latency is primarily due to distance or other factors.
-
RTT density versus geographical distance
-
RTT quartiles versus geographical distance
