ABuGET: Measuring the Non-Cooperative Available Bandwidth

Although several available bandwidth measurement tools exist, they usually require access at both ends of the measured path. In this paper, we present ABuGET, a single-ended tool for available bandwidth estimation against non-cooperative hosts. Comparing to other single-ended tools based ONE-DELAY mostly. Our measurement tool focus on utilizing ITPR (the improved PTR) algorithm to realize and exploiting TCP protocol options to initiate probing traffic. We describe the design of ABuGET. The comparison of ABuGET to Pathload (the most popular tool measuring the available bandwidth) used in simulation environments showed that our tool can provide better quality of measurements in non-cooperative environments.
