Measuring the Internet using public traceroute servers

This paper characterizes the end-to-end routing measurement infrastructure WTracer and discusses the crucial technologies. Although WTracer is a traceroute server based Internet measurement infrastructure, it can be used in many areas, such as measurement and analysis of end-to-end routing behavior of the Internet, the estimation of the global Internet host distances, the measurement of hop count in the Internet, the discovery of Internet topology at both router level and AS level so on.
