Test and performance comparison of end-to-end available bandwidth measurement tools

The bandwidth measurement is essential for resource management, provisioning of network. There are many measurements techniques and tools, but the accuracy and intrusiveness of these tools are not much shown concurrently in a paper. Thus, we survey bandwidth measurement tools and evaluate performance of some well-known tools. In this paper, we present measurement results in accuracy and intrusiveness perspectives with IGI-PTR, pathChirp. Also, we present traffic volume of probing packets and measurement time using probing packet inspection with tcpdump. The test results give us information about what we should consider when we measure bandwidth.
