基于CBR指数与EoFgu的电力系统高隔离性以太网技术研究
Research on High Isolation Ethernet Technology in Power Systems Based on CBR Index and EoFgu
摘要
Abstract
To ensure the stability of the power communication system,the strategies for improving small granularity slicing and constant bit rate(CBR)business that based on flexible Ethernet(FlexE)/slicing packet network(SPN)devices are proposed.This strategy establishes a framework for slicing packet network that supports small granularity slicing together with a protection switching approach.At the same time,in order to ensure the adaptability of high-isolation Ethernet for the power systems,the Operation Administration and Maintenance(OAM)configuration process for Ethernet is optimized.Furthermore,to address the issue of clock jitter,a clock recovery method based on the improved direct digital frequency synthesizer is proposed.Experimental analysis shows that when the byte size is 200 B,the latency of network devices based on EoFgu-CBR is 117 μs,which is lower than that of devices from other manufacturers.This indicates that the proposed strategy for small granularity slicing and CBR business based on FlexE/SPN devices can effectively guarantee the real-time performance of power system communications.关键词
