Median RTT per country and US state
Mapping RTT by political boundaries can reveal where high latency issues are located.
-
Median RTT per country and US state
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
RTT Distribution
An RTT distribution shows the general latency between a monitor and the rest of the Internet.
-
CCDF of destination RTTs

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
