Measuring Bottleneck Bandwidth of Targeted Path Segments
Abstract— Accurate measurement of network bandwidth is crucial for network management applications as well as flexible Internet applications and protocols which actively manage and dynamically adapt to changing utilization of network resources. Extensive work has focused on two approaches to measuring bandwidth: measuring it hop-by-hop, and measuring it end-toend along a path. Unfortunately, best-practice techniques for the former are inefficient, and techniques for the latter are only able to observe bottlenecks visible at end-to-end scope. In this paper, we develop end-to-end probing methods which can measure bottleneck bandwidth along arbitrary, targeted subpaths of a path in the network, including subpaths shared by a set of flows. We evaluate our technique through extensive ns simulations, then provide a comparative Internet perfomance evaluation against hop-by-hop techniques. We also describe a number of applications which we foresee as standing to benefit from solutions to...
