Research on SPN Networking and Service Bearing Solution for Railway 5G-R System
摘要
Abstract
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.关键词
