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.
