The 5G Internet

The foreseen increase in the number of services and applications, coupled with ever more 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 (Internet Protocol), IPSec (IP Security), DiffServ (Differentiated Services), HIP (Host Identity Protocol), RSerPool (Reliable Server Pooling), SCTP (Stream Control Transmission Protocol), LISP (Locator/Identifier Separation Protocol), IPv6 (IP version 6) and Shim6 (Site Multihoming by IPv6 Intermediation). 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 widely accepted future Internet paradigms, such as the Internet of Things, Software Defined Networking, Network Function Virtualisation, Mobility and the notion of the ‘Differentiation of services with aggregate resource control framework’. Moreover, we introduce a ‘resource over provisioning’ approach and design guidelines as a potential solution for effective use of network capacity in the 5G internet.
