Archipelago Monitor Locations

Archipelago (Ark): CAIDA's active measurement infrastructure serving the network research community since 2007.

This page provides an interactive map and listing of Ark monitor locations and individual monitor characteristics. For a listing of other CAIDA active and passive data monitors, see the CAIDA Data Monitors page.

|   Ark Monitors:    Hosting an Ark Monitor    Locations    Data Coverage    Statistics   |

This map shows current active Archipelago (Ark) monitors at their approximate geographical location. The checkbox menus allow the selection of monitors shown based on several characteristics. Note that the locations are displayed at city granularity. When the menu selection leads to multiple monitors in the same city with different characteristics the color white is used for that city.

The team menu refers to the team probing methodology used by Ark: monitors are grouped into teams that dynamically divide up the measurement work among team members. This parallelization allows us to obtain a traceroute measurement to all routed /24's in a short period of time. For more details see the Archipelago project page.

In the menu the "Hardware" column selects monitors running FreeBSD (used for the first Ark monitors), and Linux on Raspberry Pi (the current default for new monitors).

The "Classification" column selects monitors based on a classification of the hosting location. We currently differentiate betwee infrastructure network, educational network, research network, commercial network, business and residential deployments.

The "Activity" column select monitors based on the research projects that they currently support. Access to the data from "Team-probing", "Prefix-probing", and "IPv6 probing is provided by CAIDA to researchers on request. Congestion and IODA are measurement projects still under development.

The "Status" column divides all monitors into "live" monitors, defined as a monitor that has produced data in the last recent 30 days, and "benched" monitors that have been inactive for more than 30 days.

The table below the map provides additional information: monitors that probe in IPv6 are marked with a black star (★) in the column with heading. 'IPv6'; a red star (★) in the last column (with heading 'ORGANIZATION') indicates that the hardware for the monitor was contributed by the host organization. The column with heading 'RasPi' indicates monitors deployed on a Raspberry Pi. Monitor deployments at residential locations (in increasing fraction of Ark deployments) are marked in the column with heading 'Res'.
