The networked systems area has developed, in the last 10 years, even thanks to the successful participation in 25 major advanced research projects mainly financed by the European Union, and carried on together with the major European ICT players.

The research activities  mainly deal with the design, simulation, and implementation of a technology independent "convergence layer" allowing the interoperation among heterogeneous networks (most of the activities concern telecommunication networks, but even large industrial networks, robotic networks, energy networks and transport networks are being considered), as well as the efficient and flexible handling of network resources and services/contents. Such a convergence layer, on the basis of the sensing of appropriate heterogeneous information (which can be subject to errors and could be limited) and its conversion and aggregation in homogeneous metadata, includes advanced control algorithms (methodologies such as bounded optimal control, predictive control and robust control are used) taking decisions concerning the management of the network resources, as well as the management of network contents/services; robustness of the controllers to uncertainties, as well as to delays and loss of information is a key  issue of such control algorithms. These decisions are properly actuated in the network.

The networked systems area is supporting a Future Internet vision in which the convergence layer becomes a sort of "embedded mind" of the network; in this vision all network control tasks are gradually moved in such convergence layer allowing cross-layering, cross-network optimization. According to this vision, the present control layering stack, becomes a sort of star with the  above-mentioned embedded mind being the center of the star.

Such a convergence layer is distributed among appropriate network entities (each one availing of a portion of the whole input information): thus, enhancement of distributed control algorithms is essential.
The networked systems area plans to apply these concepts, in addition to telecommunication networks, to large-scale industrial networks, robotic networks, energy networks, and transport networks.
