Abstract
We present Scriptroute, a system that allows ordinary
Internet users to conduct network measurements from
remote vantage points. We seek to combine the flex-
ibility found in dedicated measurement testbeds such
as NIMI with the general accessibility and popularity
of Web-based public traceroute servers. To use Scrip-
troute, clients use DNS to discover measurement servers
and then submit a measurement script for execution in
a sandboxed, resource-limited environment. The servers
ensure that the script does not expose the network to at-
tack by applying source- and destination-specific filters
and security checks, and by rate-limiting traffic.
Scriptroute code is publicly available and has been de-
