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 protocol menu selects on monitors doing IPv4 measurements only, and monitors doing both IPv4 and IPv6 measurements.

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.

The operating system menu selects monitors running FreeBSD (used for the first Ark monitors), and Linux on Raspberry Pi (the current default for new monitors).

The monitor class menu 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 table provides additional information: monitors that probe in IPv6 (in addition to IPv4) 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 are marked in the column with heading 'Res'. The 'Status' contains a link to an Xively URL with timeseries graphs of several hard- and software properties for the indicated monitors.
