Executive Summary

Several wide-area services are increasingly relying on bottleneck bandwidth estimation tools to enhance their network performance. Selfish hosts have, therefore, considerable incentives to fake their bandwidths in order to increase their benefit in the network. In this paper, the authors address this problem and they investigate the vulnerabilities of current bottleneck bandwidth estimation techniques in adversarial settings. They show that finding "Full-fledged" solutions for the multitude of attacks on the end-to-end bandwidth estimation process might not be feasible in the absence of trusted network components; they discuss solutions that make use of such trusted components.
