One of the key use cases for the future 5G network is the massive machine-to-machine communication for the Internet of Things (IoT) area, fulfilling a broad set of requirements, from massive bandwidth to extremely low latency and the huge heterogeneity of end devices. Subsequently, the network has to provide the IoT domain a dedicated network slice from the physical network. The network slicing concept describes a logical segment of a physical network guaranteeing a set of QoS requirements. More importantly, they are ensured for end-to-end communication, not only at the radio access segment, but also at the network core. The whole network infrastructure needs to provide provisioning, managing association to slices, interoperating and supporting performance and isolation [1].

To realize the concept of network slicing in 5G systems, Software Defined Networking (SDN) and Network Function Virtualization …
