面向铁路5G-R的SPN组网及业务承载方案研究OA
Research on SPN Networking and Service Bearing Solution for Railway 5G-R System
基于铁路5G-R业务的应用场景和运营商规模商用的SPN创新承载技术;针对不同铁路线路场景,提出一种面向铁路5G-R的切片分组网(Slicing Packet Network,SPN)方案,结合差异化5G-R业务需求,提出针对性的小颗粒硬管道业务模型和三层虚拟专用网络(Layer 3 Virtual Private Network,L3VPN)到边缘的分组业务模型部署方案.该方案满足铁路行车控制类业务高可靠、高安全的硬隔离承载需求,同时满足5G-R大带宽的视频业务、数据业务灵活调度、智能运维、高可靠和持续大带宽演进诉求,为铁路5G-R的承载网络建设提供部署方案和应用建议.
Based on the application scenarios of railway 5G-R service and the innovative bearing technology of SPN for large-scale commercial use by operators,this paper proposes an SPN networking solution for railway 5G-R systems based on different railway line scenarios.Based on differentiated 5G-R service requirements,it also proposes targeted deployment solutions for small particle hard pipeline service models and L3VPN-to-edge packet service models.This solution addresses the demands for high reliability and high security hard isolation and bearing of railway traffic control services,and also meets the demands of 5G-R large bandwidth video boarding,flexible scheduling of data services,artificial intelligence for IT operations,high reliability and continuous large bandwidth evolution.It provides deployment plans and application suggestions for the construction of railway 5G-R bearer network.
