UO Joins Two Major Internet Measurement Projects

The University of Oregon recently joined two major Internet measurement projects that are analyzing Internet topology and performance. The first is a skitter project run by the Cooperative Association for Internet Data Analysis (CAIDA), and the other is a multicast project conducted by the National Laboratory for Applied Internet Research (NLANR).

CAIDA. CAIDA 's project uses a skitter tool to measure IP paths, collect round-trip performance data, track persistent routing changes, and help visualize network connectivity.

The UO 's skitter box is one of less than two dozen deployed worldwide and is one of only two university skitter boxes in the world (the other is at the University of Waikato in New Zealand).

More information about skitter is available at http://www.caida.org/tools/measurement/skitter/index.xml

NLANR. The UO is also one of several dozen sites participating in the NLANR Multicast Beacon project (http://dast.nlanr.net/Projects/Beacon/), an active measurement project designed to provide selected IP multicast measurements for Internet sites such as loss, delay, jitter, out of order and duplicate multicast packets.
