In the near future, the high volume of content together with new emerging and mission critical applications is expected to stress the Internet to such a degree that it will possibly not be able to respond adequately to its new role. This challenge has motivated many groups and research initiatives worldwide to search for structural modifications to the Internet architecture in order to be able to face the new requirements. This paper is based on the results of the Future Internet Architecture (FIArch) group organized and coordinated by the European Commission (EC) and aims to capture the group’s view on the Future Internet Architecture issue.

One of the key aspect fundamentally missing from the current Internet infrastructure is an advanced service networking platform and facilities, which take advantage of flexible sharing of available connectivity, computation, and storage resources. This paper aims to explore the architectural co-existence of new and legacy services and networks, via virtualisation of connectivity and computation resources and self-management capabilities, by fully integrating networking with cloud computing in order to create In-Network Clouds. It also presents the designs and experiments with a number of In-Network Clouds platforms, which have the aim to create a flexible environment for autonomic deployment and management of virtual networks and services as experimented with and validated on large-scale testbeds.

This chapter is committed to give a comprehensive overview of the scalability problems of mobile Internet nowadays and to show how the concept of flat and ultra flat architectures emerges due to its suitability and applicability for the future Internet. It also aims to introduce the basic ideas and the main paradigms behind the different flat networking approaches trying to cope with the continuously growing traffic demands. The discussion of the above areas will guide the readers from the basics of flat mobile Internet architectures to the paradigm’s complex feature set and power creating a novel Internet architecture for future mobile communications.

The Future Internet as a design conception is network and service-aware addressing social and economic trends in a service oriented way. In the Future Internet, applications transcend disciplinary and technology boundaries following interoperable reference model(s). In this paper we discuss issues about federated management targeting information sharing capabilities for heterogeneous infrastructure. In Future Internet architectures, service and network requirements act as design inputs particularly on information interoperability and cross-domain information sharing. An inter-operable, extensible, reusable and manageable new Internet reference model is critical for Future Internet realisation and deployment. The reference model must rely on the fact that high-level applications make use of diverse infrastructure representations and not use of resources directly. So when resources are not being required to support or deploy services they can be used in other tasks or services. As implementation challenge for controlling and harmonising these entire resource management requirements, the federation paradigm emerges as a tentative approach and potentially optimal solution. We address challenges for a future Internet Architecture perspective using federation. We also provide, in a form of realistic implementations, research results and solutions addressing rationale for federation, all this activities are developed under the umbrella of federated management activity in the Future Internet.

Numerous projects in the area of Real-World Internet (RWI), Internet of Things (IoT), and Internet Connected Objects have proposed architectures for the systems they develop. All of these systems are faced with very similar problems in their architecture and design and interoperability among these systems is limited. To address these issues and to speed up development and deployment while at the same time reduce development and maintenance costs, reference architectures are an appropriate tool. As reference architectures require agreement among all stakeholders, they are usually developed in an incremental process. This paper presents the current status of our work on a reference architecture for the RWI as an architectural blueprint.

The current debate around the future of the Internet has brought to front the concept of “Content-Centric” architecture, lying between the Web of Documents and the generalized Web of Data, in which explicit data are embedded in structured documents enabling the consistent support for the direct manipulation of information fragments. In this paper we present the InterDataNet (IDN) infrastructure technology designed to allow the RESTful management of interlinked information resources structured around documents. IDN deals with globally identified, addressable and reusable information fragments; it adopts an URI-based addressing scheme; it provides a simple, uniform Web-based interface to distributed heterogeneous information management; it endows information fragments with collaboration-oriented properties, namely: privacy, licensing, security, provenance, consistency, versioning and availability; it glues together reusable information fragments into meaningful structured and integrated documents without the need of a pre-defined schema.

This Chapter proposes a novel Cognitive Framework as reference architecture for the Future Internet (FI), which is based on so-called . The objective of the proposed architecture is twofold. On one hand, it aims at achieving a full interoperation among the different entities constituting the ICT environment, by means of the introduction of , in charge of virtualizing the heterogeneous entities interfacing the FI framework. On the other hand, it aims at achieving an inter-network and inter-layer cross-optimization by means of a set of so-called , which are in charge of taking consistent and coordinated decisions according to a fully cognitive approach, availing of information coming from both the transport and the service/content layers of all networks. Preliminary test studies, realized in a home environment, confirm the potentialities of the proposed solution.

The currently Internet foundation is characterized on the interconnection of end-hosts exchanging information through its network interfaces usually identified by IP addresses. Notwithstanding its benefits, the TCP/IP architecture had not a bold evolution in contrast with the augmenting and real trends in networks, becoming service-aware. An Internet of active social, mobile and voracious content producers and consumers. Considering the limitations of the current Internet architecture, the envisaged scenarios and work efforts for Future Internet, this paper presents a contribution for the interaction between entities through the formalization of the Entity Title Model.

Overlay applications generate huge amounts of traffic in the Internet, which determines a problem for Internet Service Providers, since it results in high charges for inter-domain traffic. Traditional traffic management techniques cannot deal successfully with overlay traffic. An incentive-based approach that employs economic concepts and mechanisms is required in order to deal with the overlay traffic in a way that is mutually beneficial for all stakeholders of the Future Internet. This "TripleWin" situation is the target of Economic Traffic Management (ETM). A wide variety of techniques are employed by ETM for optimizing overlay traffic management considering performance requirements of overlay and underlay networks together with cost implications for ISPs. However, the assessment of ETM requires an innovative methodology. In this article this methodology is described and major results are presented as obtained accordingly from the evaluation of different ETM mechanisms.

Many, if not most, well-designed Future Internet protocols fail, and some badly-designed protocols are very successful. This somewhat depressing statement illustrates starkly the critical importance of a protocol’s deployability. We present a framework for considering deployment and adoption issues, and apply it to two protocols, Multipath TCP and Congestion Exposure, which we are developing in the Trilogy project. Careful consideration of such issues can increase the chances that a future Internet protocol is widely adopted.
