Macroscopic and microscopic techno-economic analyses highlighting aspects of 5G transport network deployments

5G networks will comprise multiple, versatile infrastructures at finest granularity consisting of multiple disaggregated pools of network, compute and storage resources. To support the 5G network architectures and satisfy the access network demanding performance requirements, transport networks consisting of various converging technologies shall provide mechanisms to support deployment flexibility and scalability. The various deployment alternatives of transport network technologies and topologies in real network deployments shall take into account various factors such as area specifics, technologies’ deployment feasibility, traffic/usage forecasts considering long-term services roadmaps and certainly, the implicated costs. Thus, transport network planning and dimensioning shall be tightly accompanied by the techno-economic analysis of the various deployment alternatives. This paper provides insights of 5G transport network technologies and deployments as retrieved through macroscopic and microscopic technoeconomic analyses and demonstrates their applicability on the architectural concepts of 5G-PICTURE 5G-PPP project.
