Abstract

In this paper we present results of a series of end-to-end path capacity measurement experiments conducted on a fully controllable IP network built in the lab. We test and evaluate several typical path capacity measurement tools: pathchar, clink, and pathrate. The cross traffic is generated in a reproducible manner, and has similar spatial and temporal characteristics of real Internet traffics. We evaluate the measurement error and other operational characteristics of the tools and analyze factors impacting their performance. Such work is useful for tools selection and further improvement of capacity measurement tools.
