【摘要】：5G正在朝着更高速率、更低时延、更低功耗的方向迈进,前传光网络(fronthaul optical network)已成为提升其综合能力必不可少的重要手段之一.本文阐述了5G前传光网络未来发展趋势的"三一"观点(一个关键问题,一个重要特征,一个发展目标):(1)面向5G大带宽和低时延传送需求,探索光网络资源的多维度复用技术,实现海量数据的高速与低时延传送是5G前传光网络亟待解决的关键问题;(2)天线数量的激增与虚拟化技术的不断部署,导致面向5G前传光网络的拓扑不再是固定的点到点的连接形式,构建灵活与可重构的前传光网络是实现5G资源高效配置的重要特征;(3)满足不断增长的移动业务流量需求,以及物联网等多样化业务接入下的高质量数据传送,结合人工智能与机器学习,打造深度智能化的控制管理系统是未来5G前传光网络的又一发展目标.
[Abstract]:5G is moving towards higher rates, lower latency, lower power consumption, Fronthaul optical network has become one of the indispensable means to improve its comprehensive capability. This paper expounds the "three one" viewpoint of the future development trend of 5G pretransmission optical network (a key problem, an important feature, A development goal is to explore the multi-dimensional multiplexing technology of optical network resources for 5G large bandwidth and low delay transmission requirements. The high speed and low delay transmission of massive data is the key problem in 5G pretransmission optical network. The number of antennas and the deployment of virtualization technology are increasing rapidly. As a result, the topology of 5G forward optical network is no longer a fixed point-to-point connection form. Constructing a flexible and reconfigurable forward optical network is an important feature of implementing 5G resource efficient configuration. It is also another development goal of 5G pretransmission optical network in the future to build a deep intelligent control management system based on the combination of artificial intelligence and machine learning and the high quality data transmission under the diversified business access such as the Internet of things.
