SDN在轨道交通通信网络中的应用

虽然5G通信技术日渐成熟,互联网业务高速发展,但在轨道交通的应用中,5G通信技术仍然存在许多挑战。将SDN技术应用在轨道交通通信网络技术中,实现网络设备的控制面和用户面的分离解耦,可以提高网络性能和数据管控能力,减小开发成本,提高资源管控效率。本文将结合既有的技术和文献资料,综述SDN在5G轨道交通通信网络中的研究与应用情况,并讨论软件定义网络在轨道交通通信系统应用中的挑战。

Despite the increasing maturity of 5G communication technology and the rapid development of Internet business,5G communication technology still faces many challenges in the application of railway.The application of SDN technology in railway communication network can realize the separation and decoupling of control plane and user plane of network equipment,improving network performance,data management and control ability,which can reduce the development cost,and improve resource management and control efficiency.This paper will combine existing technology and literature the research and application of SDN in 5G railway communication network,confirming the importance of software defined network in the construction of future railway communication system.
