Executive Summary

The diversity of end-to-end (e2e) Internet routes has been studied for over a decade, dating back to Paxson's seminal work from 1995. This paper presents a measurement study of this issue and systematically evaluate the diversity of the Internet routes, while revisiting some of the conclusions previously made. Two large scale experiments are used for evaluation, one executed in late 2006 and the second in early 2009, both employ a set of more than 100 broadly distributed vantage points, actively measuring between each other. The authors find that although e2e routes are quite diverse, they are relatively stable, albeit with high variance between different vantage points, with strong dependency on the network type (academic vs. commercial).
