Available Bandwidth Estimation Tools Metrics, Approaches and Performance

The estimation of the available bandwidth (av bw) between two end nodes through Internet, is an area that has motivated researchers around world in last twenty years, to have faster and more accurate tools; Due utility it various network applications; Such as routing management, intrusion detection systems performance transport protocols. Different tools use different techniques but generally only analyze three most used metrics av bw, relative error time. This work expands information regarding evaluation literature current Available Bandwidth Estimation Tools (ABET’s), where they techniques, metrics, generation cross-traf?c testbed; Concentrating on methodologies used, well challenges faced by open-source high-performance networks 10Gbps or higher.
