Vela provides an easy way for researchers to conduct on-demand topology measurements on Ark. Users can conduct ping and traceroute measurements in IPv4 and IPv6 using ICMP, UDP, or TCP from any Ark monitor.
There are two interfaces to Vela, a command-line interface and a web-based interface. The command-line interface is useful for conducting large-scale feedback-driven, dynamic measurements under the full control of the user's own program (written in any language of the user's choosing, such as Perl, Python, Ruby, or C). The web interface is useful for interactively performing ad-hoc exploratory measurements.
We are currently limiting access to the Vela web interface to academic researchers. We hope to provide access to network operators in the future. Please request a Vela web account by completing the Vela Account Request form.
About the Name Vela
Vela (pronounced VEE-luh) is Latin for the sails of a ship. It is also a constellation representing the sails of the ship Argo Navis, the ship used by Jason and the Argonauts in Greek mythology. We like the idea of the Vela service being the "sails" used by researchers to travel on the Ark infrastructure.
