The foreseen increase in the number of services and applications, coupled with evermore stringent Quality of Service (QoS) requirements, will require more muscle from what the Internet can deliver today. Today we have a differentiated services framework, with evolutionary approach supplements, such as Mobile IP, IPSec, DiffServ, HIP, RSerPool, SCTP, LISP, Shim6 or IPv6. However, the current Internet ecosystem still harbours severe shortcomings, in terms of performance, reliability, scalability, security and many other categories including societal, economical and business aspects, which have led to Future Internet research efforts. Quite clearly, the existing Internet needs to evolve to be ready for 5G services. The European Commission (EC) Future Internet Architecture (FIArch) Experts Reference Group (ERG) has analysed the existing design principles, and initiated efforts for developing novel ones. This chapter specifically addresses a consolidated step in the research community towards answering new principles, inspired by important aspects for the Future Internet cloud, such as the Internet of Things, Software Defined Networking, Network Function Virtualization, Mobility and the notion of the “Differentiation of services with aggregate resource control framework”. Moreover, we introduce a “resource over provisioning” approach and guidelines as a potential solution for effective use of network capacity in the 5G internet.
