CAIDA’s 2006 Annual Report covers last year’s efforts, summarizing highlights from our research, infrastructure, and outreach activities. Our current research projects, primarily funded by the U.S. National Science Foundation (NSF), include several measurement-based studies of the Internet’s core infrastructure, with focus on the health and integrity of the global Internet’s topology, routing, addressing, and naming system. Our infrastructure activities, funded by NSF and DHS as well as other government and industry sources, include building a catalog of Internet measurement data sets, contributing to the (DHS-funded) PREDICT repository of datasets to support the (U.S.-based) network research community, and developing and deploying active and passive measurement infrastructure that cost-effectively supports the global Internet research community. We also lead and participate in tool development to support measurement, analysis, indexing, and dissemination of data from operational global Internet infrastructure. Finally, we engage in a variety of outreach activities, including web sites, peer-reviewed papers, technical reports, presentations, blogging, animations, and workshops. CAIDA’s program plan for 2007-2010 will be available in July 2007.

[okay, that took about four times as long as i’d hoped, but we’re done with a preliminary cataloging of the data collected for our “Day in the Life of the Internet” experiment for 2007. -k]
As a refresher, this is a follow-up to our last year’s announcement that we would try out this experiment recommended by a National Academy of Sciences workshop, specifically, to capture ‘a day in the life of the Internet’ (DITL) to support the needs of network research. We believe the research community now has more measurement data (indexed!) than ever before about a single day of the Internet, and while the data situation is still pretty bleak, a little data is better than even less. In terms of measurements executed, we did significantly better than our practice DITL run in 2006, so there is cause for optimism about the future of this kind of experiment. As the summary makes clear, this year’s progress was mostly due to contributions from outside the U.S., in particular from Korea and Japan, countries which have generally more successfully navigated data sharing issues for their research communities than the U.S. has. We are sorry to say we did not index a single trace from a commercial provider link this year, although we were pleased to get participation from 5 of the 13 root nameserver anycast cluster operators, up from 3 last year.
