The wide deployment of Internet of Things (IoT) applications raises the need for underlying environments and infrastructures that can both support the traffic data requirements and enable the process of distributed IoT data. 5G-the fifth generation of mobile, cellular technologies, networks and solutions, provides the enabling environments to fulfil the aforementioned IoT applications diverse requirements. 5G promises to bring the reliability, latency, scalability and adaptability that would be needed for several services in the IoT space and beyond. To satisfy these demands, network slicing has been envisioned as the promising solution in an IoT-oriented 5G architecture. In this paper we propose an efficient IoT-oriented architecture supporting network slicing for 5G-enabled IoT services over the 5G Core, in order to meet the requirements for establishing an efficient network with high capacity, while ensuring the maximum Quality of Service (QoS) to the end users-applications.

A key feature of fifth generation (5G) and Software Defined Networking (SDN) is the assurance of high levels of the quality of service (QoS). To this end, Service Level Agreements (SLAs) are introduced in order to fulfill the gap between network operators and their customers. An SLA is a contract between the operator and the internal or external customer, which determines what Network Services (NSs) are offered and the guaranteed level of performance. Taking into consideration the above-mentioned needs, in this paper, we are introducing a fully integrated SLA management framework in a real 5G environment. In this demonstration we aim to bind business requirements as Service Level Objectives (SLOs) between network operators and the customers, with measurable recourse attributes. To achieve this, we allow network operators to choose between different SLOs during the SLA Template generation, and then automatically formulate an Agreement, based on each network slice instantiation and the corresponding NS. Finally, we provide a monitoring system in order to detect and alert for any violations.

Unlike previous generations, 5G will need to be faster, more efficient, reliable, flexible, agile, and, at the same time, cost less. For this to be possible, 5G has to engage with the best-of-breed of the emerging technologies, where NFV is definitely in the top list. In this context, this paper describes the SONATA Service Platform, an open source MANO framework extended in the scope of the 5GTANGO H2020 project. In particular, this demo presents some features that go beyond the stateof-the-art including Monitoring, Policy, and SLA Management.
