摘要: 边缘计算技术不仅可以大大减少端到端的业务时延,还可以有效降低数据回传至核心网引起的回传带宽,因此边缘计算技术在铁路中的应用值得深入研究。首先介绍5G网络中边缘计算的系统架构,其次介绍边缘计算常见的3种分流方案,并对其适用场景进行分析,最后结合铁路客站、货站、线路、列车4种应用场景的业务特点,提出网络边缘计算部署建议,以供今后铁路5G边缘计算应用借鉴参考。

Abstract: The edge computing technology can not only greatly reduce the end-to-end service delay, but also effectively reduce the back bandwidth caused by data back to the core network. Therefore, the application of edge computing technology in railway is worth further study. This paper first introduces the system architecture of edge computing in 5G network, then introduces three common diversion schemes of edge computing, and analyzes their application scenarios. Finally, combined with the service characteristics of four application scenarios of railway passenger station, freight station, line and train, this paper puts forward the deployment suggestions of network edge computing for reference for future railway 5G edge computing applications.

Key words: railway, 5G network, edge computing, diversion scheme, deployment suggestions
