Cloud Assisted Overlay Routing

Abstract

Delay is a crucial factor on the Internet especially for real-time multimedia and interactive applications like videoconferencing, gaming. The best-effort service model doesn't provide essential assistance to these applications because of the unstable queuing delays. Cloud infrastructures have being used heavily for content delivery by replicating the original content prior to demand. In this work, we investigate if cloud can also help to improve delay-sensitive real-time interactive applications. In other words, is it possible to obtain shorter and more stable delays through cloud nodes. In order to answer this question, we have done a measurement study which are performed between some vantage points using PlanetLab and public cloud platforms. We investigate the experiment outcomes from different perspectives by analyzing various statistics and characteristics. We infer from the results that utilizing cloud nodes as proxy reduces path length while navigating between two points on the Internet.
