Overview The project's goal is to collect, distribute, and analyze an unprecedented data set: an annotated map of the entire Internet, complete with a rich set of link attributes (delay, loss, capacity, congestion), a rich set of router attributes (alias resolution, geographic location, structural role, and failure rate), and operational policy (intradomain and interdomain routing policy). The map is measured continuously over time to provide a view on the evolution of these properties over time. There are many benefits to collecting, distributing and analyzing a comprehensive map of the Internet, annotated with a rich set of attributes. These include revolutionizing our understanding of the Internet, aiding the evaluation of network architectures and network protocols, and providing realtime data to optimize distributed services. Current research efforts include:
Reverse Traceroute: A system to measure reverse paths back to the user, complementing the forward path information provided by traceroute.
Internet Maps: Efficient collection of link and router attributes at Internet scale from hundreds of vantage points without incurring prohibitive measurement traffic. iPlane: A scalable service providing accurate predictions of Internet path performance for emerging overlay services. Hubble: A system to detect, monitor, and classify black holes and reachability problems in real-time on the Internet. IP Geolocation: Automated solution for determining the geographic location of an Internet host using network measurements. BitProbes: Measurement system that leverages BitTorrent for large-scale Internet measurements to edge systems. Rocketfuel: An ISP toplogy mapping engine that uses routing information to measure an ISP at a time. |
