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

Path Length Distributions

Path length distributions show, on aggregate, how well-connected a monitor is to the rest of the Internet.

RTT Distribution

An RTT distribution shows the general latency between a monitor and the rest of the Internet.

CCDF of destination RTTs

percentile 10th 25th 50th 75th 90th

RTT (ms) 49.800 73.426 149.410 192.233 249.092
RTT quartiles vs hop distance


percentile	10th	25th	50th	75th	90th
RTT (ms)	49.800	73.426	149.410	192.233	249.092

RTTs vs. Distance

Comparing RTT with geographical distance helps show if latency is primarily due to distance or other factors.
