Abstract

Most bandwidth estimation tools require access to both ends of a measured path, which is increasingly difficult considering the constantly expanding size of the Internet. We present Pathperf, a tool for estimating bulk transfer capacity by downloading files from websites at one end of a path. We collect 3.3 million websites in 22,656 ASes and leverage DNS infrastructure to deliver website information. Comparing with Iperf, Pathperf saves more than 50% of the network traffic and its relative error rate is under 10%.
