Network management has failed to cope properly with the amazing increase in diversity, scale and scope of the Internet, which leads in turn to the Internet lacking the kind of reliability, robustness, and predictable performance we expect from critical infrastructure. Future Internet growth will require not only new technology and evolution of access performance but also a better way to manage this distributed high performance architecture. The Leone project seeks to build a network management framework that integrates an unprecedented number and diversity of sources of information about the network and its performance, including measurements focussed on the quality of experience perceived by the end users in a world of highly distributed and increasingly meshed applications.

The Leone consortium will research, prototype and validate through trials several tools that instantiate our framework:

• New tests running on the probes, to measure Quality of Experience. We build on the existing global platform of our partner SamKnows, which already has several thousand probes in the homes of broadband customers, by deploying 100 probes in partner ISP networks
• Analysis to determine the cause of degradation of Quality of Experience. The tool combines the multiple viewpoints provided by the multi-dimensional data, in order to isolate which part of the Internet or service infrastructure has failed or needs to be upgraded.
• Visualization of the measurements and analysis results.
• Integration of the measurements and analysis results into existing network management tools, exemplified by the tool of our partner MG-Soft.
• Automatic repair of the problem, where possible in some scenarios.
