The ubiquity of Internet access, the wide variety of devices for WEB browsing and the use of heterogeneous applications, have made the internet become one of the main pillars of the information society. However, its distributed nature entails some fragility and induces real operational difficulties in the research and identification of the causes of the problems related to the availability of services and the performance of connections. The first step in improving this situation is "measuring" through automatic control plans to identify and predict the currently obscure dynamics that reduce network performance. The project this is in summary the purpose of the Mplane project, which consists of a geographically distributed measurement infrastructure, capable of actively executing, passively and in hybrid mode, several measurements in a dynamic way. All data will be recorded in a repository where, through parallel processing and data mining techniques, it will be possible to derive analyses and models that can identify the "bottlenecks" and improve the communications of the network. The results of the project will be useful both to Internet providers (ISPs) who will be able to have the complete data of their infrastructure, and if necessary to improve their service levels, while the application providers gain important indicators for Improve the management of your applications ' performance issues. The numbers of the project project funded under the 7 Framework Programme (FP7) of the European Community.
