Measuring End-to-end packet loss characteristics are modulated more accurately using Probes than in traditional way. Generally measurement and estimation of end-to-end packet loss characters are challenging due to short duration of packet loss episodes. Active probe tools are used to measure packet loss at end-to-end paths which has been show the little impact on the network. The authors begin their test by showing loss packet characteristics reported from Poisson-modulated probe tools. It can be quite inaccurate over a range of traffic conditions. By observing these conditions, they introduce a new algorithm called BADABING which measure the packet loss that is designed to overcome the deficiencies in standard Poisson-based tools.
