摘　　要：随着软件定义网络(software defined network,SDN)和网络功能虚拟化(network functions virtualization,NFV)的深入发展,5G网络切片技术将业务需求和网络资源有机结合,满足了5G时代不同垂直行业的具体功能需求。智能电网各应用场景满足切片灵活创建、高效运行及动态更新的全过程管理需求,支持移动性、安全性、可靠性、大带宽、低时延等差异化网络的服务需求。文章首先分析5G时代下典型电力业务的通信需求,然后介绍网络切片的基本概念及电力业务的3种典型场景,并提出网络切片在电力业务场景下的具体方案,最后通过实际测试验证网络切片应用于电力业务中的可行性和适用性。With the further development of SDN(software defined network)and NFV(network functions virtualization),the 5G network slicing technology with the two techniques considering the business requirements and network resources can meet the specific functional needs of different vertical industries in the 5G era.Each application scenario of the smart grid requires flexible slice creation,efficient operation,and dynamic update of the whole process management requirements,and supports the service requirements of differentiated networks such as mobility,security,reliability,large bandwidth,and low latency.This paper first analyzes the communication requirements of typical power services in the 5G era,then introduces the basic concepts of network slicing and three typical scenarios in power services,and proposes specific solutions for network slicing in power business scenarios.Finally,the feasibility and applicability of network slicing applied in power business are verified through practical test.
