The 5G network is virtualized through a complex interlinking of individual components running as Virtual Network Functions (VNFs), and network slicing. While VNFs have been around for a while, network slicing presents itself as the next step in SDN technology—amounting to full virtualization of the network from radio to core. The separation of the network
With the advent of 5G, a much more highly virtualized and dense mobile network infrastructure will place greater demands on management. 5G virtualization presents new challenges, both through individual components running as Virtual Network Functions (VNFs) and through network slicing, chiefly because these factors result in complex networks and consequently, much more complex network management.
