Abstract

The growth of Internet eXchange Points (IXPs) as an important component in the Internet Autonomous System (AS) level topology has led to the need for a detailed evaluation of their effect on Internet topology evolution and inter-domain packet routing. In this work, we carry out initial measurements to analyze the effect of the additional peering links and observe path quality in terms of round-trip time and loss rates of routes going through an IXP between pairs of Internet hosts. We observe significant effects of IXP-links on Internet growth and topology evolution while the routing performance points to numerous cases of Triangle Inequality Violations (TIVs) due to the IXP switches.
