Comparative Analysis of Active Bandwidth Estimation Tools

Abstract

A comparative analysis of state-of-the-art active probing tools for bandwidth estimation is outlined. Techniques and tools for capacity, available bandwidth and bulk transfer capacity estimation are simultaneously assessed. First, a generic framework for the design of active bandwidth estimation tools is proposed as a result of our analysis of the implementation and performance of a number of available techniques and tools. Then, we describe a first and comprehensive series of tests performed over a broad range of bandwidth estimation tools, scenarios and experimental conditions. These tests have been done with the aim to develop a set of practices, procedures and tools for the comparative analysis of active bandwidth estimation techniques and tools, which are presented. Finally, Overall conclusions are discussed and pointers to publicly available records and tools are given.
