Evaluation of a New Method for Measuring the Internet Degree Distribution: Simulation Results

Free registration required

Executive Summary

Many contributions rely on the degree distribution of the Internet topology. However, current knowledge of this property is based on biased and erroneous measurements and is subject to much debate. Recently, a new approach, referred to as the Neighborhood Flooding method, was proposed to avoid issues raised by classical measurements. It aims at measuring the neighborhood of Internet core routers by sending trace-route probes from many monitors distributed in the Internet towards a given target router. In this paper, the authors investigate the accuracy of this method with simulations.
