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.

5G网络将以最精细的粒度包含多个通用基础设施，其中包括多个分散的网络，计算和存储资源池。为了支持5G网络架构并满足接入网对性能的苛刻要求，由各种融合技术组成的传输网络应提供支持部署灵活性和可扩展性的机制。在实际网络部署中，传输网络技术和拓扑的各种部署替代方案应考虑到各种因素，例如区域详细信息，技术的部署可行性，考虑到长期服务路线图的流量/使用情况预测，当然还包括相关成本。从而，运输网络的规划和规模确定应紧密结合各种部署替代方案的技术经济分析。本文提供了从宏观和微观技术经济分析中检索到的5G传输网络技术和部署的见解，并展示了它们在5G-PICTURE 5G-PPP项目的体系结构概念上的适用性。
