Abstract-Recent endeavors in addressing the challenges of the current and future Internet pursue a clean slate design methodology. Simultaneously, it is argued that the Internet is unlikely to be changed in one fell swoop and that its next generation requires an evolutionary design approach. Recognizing both positions, we claim that cleanness and evolution are not mutually exclusive, but rather complementary and indispensable properties for sustainable management in the future Internet.In this paper we propose the in-network management (INM) paradigm, which adopts a clean slate design approach to the management of future communication networks that is brought about by evolutionary design principles. The proposed paradigm builds on embedded management capabilities to address the intrinsic nature, and hence, close relationship between the network and its management. At the same time, INM assists in the gradual adoption of embedded self-managing processes to progressively achieve adequate and practical degrees of INM. We demonstrate how INM can be exploited in current and future network management by its application to P2P networks.

Abstract-Current architectures and solutions are about to reach the limits of sustainable developments. Over the years, many new requirements have emerged, and there are observations pointing to an ever-increasing diversity in applications, services, devices, types of networks at the edge and the access. Meanwhile, the infrastructures for internetworking, connectivity, and also management remain fairly the same. A new paradigm is needed that can support a continuous high pace of innovations in all the different parts and aspects of a communication system, while at the same time keeping costs of deployment and maintenance down. This new paradigm has to embrace current trends towards increased heterogeneity, but on the other hands provide support for co-existence and interoperability between alternative and various solutions all residing within a global communication system. This paper presents a new architectural framework called the Nth Stratum concept, and which takes a holistic approach to tackle these new needs and requirements on a future communication system. Index Terms-Architecture, Framework, Stratum, System I. INTRODUCTION XISTING systems for communication like Internet are challenged by developments occurring at various parts of these systems. Especially towards the edge, new forms of applications, access networks and devices make it increasingly difficult to keep the overall communication system consistent and coherent, as well as to maintain inter-operability. One can observe a fragmentation of the system into different noninteroperable segments. Peer-to-peer technology makes new and fairly independent application-specific networks appear on top of the existing networks as overlays, and generally with nodes in such overlays being at edges. Further to this, core features such as security, mobility, and QoS, are sometimes lacking proper support, which leads to different middlebox and adhoc solutions, and not to forget about the still occurring problems with security attacks, spam, as well as maintaining the overall stability of the routing system. The challenge is an ever-increasing need to support not only a high growth of terminal entities of various kinds but also to support mobility and multi-homing. Cellular networks are challenged by the emergence of alternative and complementary radio access systems. The integration of these different types of networks calls for a flexible architecture framework, especially in view of the fast pace of application and device development. The Internet on the other hand lacks support for mobility, QoS, and security, which are fairly well supported by the cellular networks. However, Internet shows, so far, a clear advantage in supporting application development, making it relatively easier to roll-out new services Considering the status of the current systems for communication as being described above, it does not seem reasonable and feasible to continue with patching those systems with different 'fixes'. Instead we advocate that a new architectural framework is nee...

Abstract. The evolution of various wireless technologies has greatly increased the interest in heterogeneous networks, in which the mobile users can enjoy services while roaming between different networks. The current Internet architecture does not seem to cope with the modern networking trends and the growing application demands for performance, stability and efficiency, as the integration of different technologies faces many problems. In this paper, we focus on the issues raised when attempting to provide seamless mobility over a hybrid environment. We highlight the shortcomings of the current architecture, discuss some of the proposed solutions and try to identify the key choices that lead to failure. Finally, we introduce RINA (Recursive Inter-Network Architecture), a newly-proposed network architecture that achieves to integrate networks of different characteristics inherently and show a simple example that demonstrates this feature.

Abstract-MEC or Multi-Access Edge Computing is a network service delivery architecture that enables cloud computing capabilities at the edge of the access network. Realisation of the MEC vision is challenging with current network technologies: service discovery and routing, secure network slicing and distributed mobility management require complex capabilities in the network. This demo features an OMEC use case realised via RINA, the Recursive Network Architecture. RINA provides interesting properties for OMEC, due to its support for multi-homing, mobility and slicing without special protocols, and security as a first class element of the architecture.

Abstract. Future communication networks will be composed of a diversity of highly heterogeneous network variants, ranging from energy constrained wireless sensor networks to large-scale wide area networks. The fact that the size and complexity of such networks will experience tremendous growth will eventually render existing traditional network management paradigms unfeasible. We propose the radically new paradigm of in-network management, which targets the embedding of self-management capabilities deep inside the network nodes. In this paper, we focus on our framework for in-network management, which allows management logic to be embedded and executed within network nodes. Based on a specific use-case of bio-inspired network management, we demonstrate how our framework can be exploited in a network failure scenario using quorum sensing and chemotaxis.
