macroscopic topology project connectivity analysis massive macroscopic traceroute data - largest IP topology data set in world funding from NSF, DARPA, commercial sources establishing framework for topology analysis combinatorial structures (trees, acyclic part, core, giant component) description by Weibull distributions mapping IP -> AS -> city, country -> latitude, longitude BGP routing tables: IP -> prefix -> AS whois registry/hostnames: AS, IP -> city,country -> latitude,longitude note: there is no public trusted source of this data at this time (even CAIDA's has not been funded in 2 years) visualization IP paths: single source, single destination IP paths: single source, few destinations AS/country paths: single source, many destinations IP paths RTT: single source, many destinations IP topology: many sources and destinations AS topology: many sources and destinations geopolitical distribution of Internet resources
