As the Internet has penetrated everyday life, more and more users will demand high-quality services. However, the Internet was not designed to handle such heavy usage. Thus, networks need to be enhanced in order to deal with the increased traffic. In this study, the use of opportunistic networks (ONs) is studied. ONs are operator-governed, coordinated(More)
This paper briefly proposes the demonstration of a prototype system that is able to successfully govern autonomic functions and to efficiently manage virtualized resources. The demonstration also showcases how Software-Driven Networks (SDNs) can be managed using the UMF architecture, as well as how novel optimization algorithms and mechanisms can be(More)
This paper proposes the exploitation of a Unified Management Framework for coordinating (i.e. ensuring conflict-free and stable operation), multiple, autonomic control loops. The functionality is demonstrated through the instantiation to Self-Organizing Network (SON) coordination for managing LTE-Advanced Heterogeneous Network (HetNet) with relays.
Future Networks will constitute a complex, highly miscellaneous, decentralized and dynamic environment, the requirements of which cannot be handled by traditional management schemes. The alternative is the approach of governance framework of service and network management, which targets at guidance of the behavior of autonomic and legal network entities and(More)
