Towards The Quest For 5G Network Slicing


Due to the recent mobile traffic explosion, Mobile network Operators (MNOs) are severely challenged. We believe that the imminent arrival of 5G, will drive changes in communications service provider networks and address several issues by leveraging on both Network Function Virtualization (NFV) and Software Defined Networking (SDN) technologies. The upcoming 5G ecosystem will involve a number of vertical markets to give rise to a plethora of novel services with different requirements such as, Ultra-Reliable Low-Latency Communication (URLLC), machine Massive Type Communications (mMTC), and enhanced Mobile Broadband (eMBB). To be able to offer such variety of services with different needs over the same network, this latter should be split into multiple logical networks known as network slices. In this paper, we propose an architecture design for 5G network slicing inspired by ONF and 3GPP models. We have developed an OpenAPI-based architecture that provides Network Slice as a Service (NSaaS) together with their life cycle management. We have demonstrated the realization of this approach via a deployment of the URLLC, mMTC, and eMBB services on a real platform.
