FlexE承载电力业务的应用架构及测试验证

FlexE Application Architecture and Test Validation for Power Business

随着大规模配电网自动化、分布式能源接入、用户双向互动等通信业务快速发展,电网通信业务呈现出多颗粒度、安全隔离、低时延的承载需求,新一代以太网FlexE接口技术具有带宽灵活配置、硬隔离管道及超低时延的优点,能否在接入侧承载电网业务成为重要课题。文章研究了FlexE切片技术在电网中的应用架构,分析了电网典型业务对FlexE切片适配性,分别从隔离性、低时延及带宽灵活绑定3方面提出了FlexE切片技术承载电力典型业务的测试方案,为FlexE网络切片在电网中的推广应用提供测试基础。

With the rapid development of communication services such as large-scale distribution network automation,distributed energy access,and two-way user interaction,power grid communication services present the bearing requirements of multi-granularity,security isolation,and low latency.The new-generation Ethernet FlexE interface technology has the advantages of flexible bandwidth configuration,hard isolation pipes,and ultra-low latency.Whether it can carry power grid services on the access side has become an important issue.This paper studies the application architecture of FlexE slicing technology in the power grid,and analyzes the adaptability of typical grid services to FlexE slicing.A test solution for FlexE slicing technology to carry typical power services is proposed in terms of isolation,low latency and flexible bandwidth binding.This test solution provides test support for the application solution of FlexE network slicing in the power grid.
