  abstract =     "Researchers need current and historical measurements of
                  Internet paths.  We built and deployed a complete system
                  designed to fill these needs: a safe, shareable, multi-user
                  active network measurement system probes network paths and
                  reliably records measurements in a storage facility with
                  multiple levels of caching, providing users with fast,
                  flexible querying.  Our system, deployed on PlanetLab for
                  over 20~months, has accumulated 940~million measurements and
                  made them publicly available in a separate, federated data
                  repository.  Our experience shows that building and running
                  such a valuable research tool poses significant engineering
                  and practical challenges."
