基于SPN的5G+车联网的切片技术的应用与研究

Application and Research on Slicing Technology of 5G+Internet of Vehicles Based on SPN

SPN是面向5G传输网提出的创新技术体系,可实现大带宽、低时延、高效率的综合业务传输。针对5G+车联网这类垂直行业的业务需求,当前尚存在大量问题亟待解决。通过SPN试验网设计与搭建,对SPN系统中切片功能及业务承载能力进行了研究。研究测试表明:切片功能管控面可大幅度降低业务开通和维护的复杂度,转发面能基于FlexE技术实现车联网业务的隔离和带宽灵活调度功能;业务承载结合分段路由SR能有效降低业务中断风险,提高网络安全性能。

SPN is an innovative technology system proposed for 5G transmission,which can realize comprehensive service transmission with large bandwidth,low delay and high efficiency.For the service needs of vertical industries such as 5G+Internet of vehicles,there are still a lot of problems to be resolved.Through the design and construction of SPN test network,the slicing function and service carrying capacity of SPN system are studied.The research and test show that the management and control planes of the slice function can greatly reduce the complexity of service opening and maintenance,and the forwarding plane can realize the function of isolation and flexible bandwidth scheduling of the Internet of vehicles service based on FlexE technology,and the combination of service bearing and SR can effectively reduce the risk of service interruption and improve the network security performance.
