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
  

Path Length Distributions

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

• CCDF of IP path lengths for responding destinations

  percentile	10th	25th	50th	75th	90th	Max
  IP path length	12	14	16	19	20	38

  
• CCDF of AS path lengths for responding destinations

  percentile	10th	25th	50th	75th	90th	Max
  AS path length	4	5	5	6	7	13

  
• CCDF of IP path lengths for non-responding destinations

  percentile	10th	25th	50th	75th	90th	Max
  IP path length	7	10	13	16	19	47

  
• CCDF of AS path lengths for non-responding destinations

  percentile	10th	25th	50th	75th	90th	Max
  AS path length	3	4	5	5	6	13

  

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)	45.443	103.682	162.145	215.888	271.977

  
• RTT quartiles vs hop distance
  

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
