Frequent traceroute-style path probes are used to build a tree showing the paths to most of the nets on the Internet. Once the layout is computed, the map can be colored to show geographical clues, network capacity, or IP addresses. In this example, color distinguishes different ISPs.

URL: https://www.bell-labs.com/about/history/#gref Visualization Thumbnail About the Visualization Visualization Techniques: (Technique1): Graph layout treats data as a physical system and finds the set of node positions that minimizes the total energy. Any two nodes that do not share an edge are connected, via infinite strings, to a spring.

(Source2) Full network scan (this graph uses data from 28 June 1999). First, possible host names are generated for all possible destinations obtained from the routing arbiter database (Source1).

(Strength2): Collected data is available for analysis over time. Issues: (Issue1): Graph shows IP path connectivity only, not actual traffic on physical links. (Issue2): Graph reflects only outgoing packet paths.
