The fifth-generation technology standard for cellular networks (5G) aims to provide high throughput, reduced latency, massive connection and a shift from service-orientation to user-orientation in requirements and innovations. To achieve the target goals, efficient resource allocation and management are required. In this regard, the concept of Network Function Virtualization (NFV) has been introduced, as well as the one of Software Defined Network (SDN). NFV is a state-of-the-art approach which replaces whole classes of network’s nodes functions, which were generally deployed on dedicated hardware, with pure software implementations. The virtualization of radio access networks (vRAN) comes under the NFV paradigm. The goal of vRANs is to centralize the virtualized radio access point (vRAP) processing stack, and to efficiently map the users’ requirements into radio and computational resources allocation.
