A Structural Approach for PoP Geo-Location
Inferring PoP level maps is gaining interest due to its importance to many areas, e.g., for tracking the Internet evolution and studying its properties. In this paper, the authors introduce a novel structural approach to automatically generate large scale PoP level maps using trace-route measurement from multiple locations. The PoPs are first identified based on their structure, and are then assigned a location using information from several geo-location databases. They discuss the tradeoffs in this approach and provide extensive validation details. The generated maps can be widely used for research, and they provide some possible directions.
