Exploring the Congestion Level Index for Defining the QoS Performance Profile of Internet Paths

This paper

presents research into Internet Quality of Service (QoS) data capture and analysis techniques for QoS performance profiling of global Internet paths. Through a support program available to collaborators within the European Réseaux IP Européens (RIPE) Atlas project, it is possible to set-up an active Internet probing network whereby raw QoS measurements may be made and captured along selected Internet paths. Employing this facility, this paper presents a way towards developing local to global large-scale Internet QoS performance profiling. Mainly for demonstration purposes, this profiling is done for a set of radial Internet paths which cover 22 cities in eleven countries in six continents. The results, a selection of which are presented here, also may serve as a historical Internet performance benchmark for the particular Internet paths and countries investigated here.
