Future Internet will have to cope with yet unknown terminals and services (even users), in a number and heterogeneity never seen before. So, flexibility or adaptability will be considered as one of the most important design principles. This flexibility will demand different kinds of awareness both in the ends and in every node in the service supplying chain, while targeting users' satisfaction as the final goal of any management process. Although virtualization and “everything is a service” approaches seem to be promising foundations to guarantee this flexibility, Future Internet will be built upon real world mobile wireless network technologies, so that cross-layers issues and quality constraints will persist. Quality of Experience (QoE) could play a significant role there, since it could provide an unified metric, isolating users from low level details or complex NQoS definitions. We will also show an example of how user-aware network tuning mechanisms are able to provide similar users' QoE with lower resources consumption and therefore propose that QoE and *-awareness were considered in the Future Internet design from the very beginning.
