Therefore “softwarization” of 5G networks is imperative and becomes a reality through new technologies, such as Software Defined Networking (SDN), Network Function Virtualization (NFV) and Cloud Computing. In this context, this paper provides a cost model in order to estimate the Capital Expenditure (CAPEX), the Operational Expenditure (OPEX) and the Total Cost of Ownership (TCO) for the proposed architecture. Furthermore, the proposed techno- economic model is used in order to estimate the above-mentioned network costs for the proposed network architecture and these costs are compared with the corresponding costs of a traditional network architecture. The experimental results verify and even exceed the ambitious predictions for cost reduction, due to the integration of those state of the art technologies in next-generation architectures.</p>
