Data |
|
|
Data Sources:
(Source1): URL's and names of looking glass servers found on the web
(Source2): URL's and names of traceroute servers found on the web
(Source3): NetGeo database
|
Data Specification:
(Data1): NetGeo output {CITY, STATE, COUNTRY, LAT, LONG}
(Data2): GeoPlot maps (Example)
(Data3): Table containing {CITY, LINK/NAME, TYPE, LAT, LONG} (Example)
|
Data Aggregation:
Group and plot reverse tracreoute and looking glass servers on maps according to their latitude and longitude.
|
Data Filters:
None.

Evaluation |
|
|
Strengths:
(Strength1):
Useful for debugging routes (Are packets taking the best paths).
(Strength2):
Useful for investigating topologies.
|
Issues:
(Issue1): Additional services may be available depending on local configurations.
(Issue2): Links may change over time and must be periodically checked.

About the Visualization |
|
|
Visualization Techniques:
(Technique1):
Plot lat/long points using GeoPlot.
|
Key Visualization Mappings:
(Mapping1):
Point color shows the availability of looking glass and traceroute servers in
that region.
- Green = Traceroute server only
- Blue = Looking glass server only
- Red = Both traceroute and looking glass servers
|
Visualization Tools:
(Tool1) GeoPlot visualization tool by CAIDA
(Tool2) NetGeo utilities by CAIDA
(Tool3) Maps provided by VisualRoute
