摘要
FlexE是承载网实现业务隔离承载和网络切片的一种接口技术,因其能实现带宽灵活可调且传输管道隔离,与5G业务特点完美契合受到主流运营商、供应商的认可。但传统的FlexE切片的颗粒度大,不适应能源互联网小颗粒度业务的需求,所以在传统5 Gbit/s颗粒的基础上引入小颗粒切片技术划分出最小粒度10 Mbit/s的传输管道的方案。文章提出了引入FlexE技术的捆绑、通道化、子速率、交叉等功能特性来适配能源互联网,为电网端到端的业务提供差异化服务,保障关键业务的可靠、低时延、安全传输,提升了能源互联网的传输效率,也简化了光传输网络设备之间的映射关系。
FlexE is an interface technology of bearer network to realize service isolation bearer and network slicing. It has been recognized by mainstream operators and suppliers because it can realize flexible and adjustable bandwidth and isolation of transmission pipeline, and perfectly fit with the characteristics of 5G business. However, the traditional FlexE slicing has a large particle size and does not meet the needs of energy Internet small-particle business. Therefore, based on the traditional 5 Gbps particle size, the smallparticle slicing technology is introduced to divide the transmission pipeline with the minimum particle size of 10 Mbps. This paper introduces the FlexE technology with binding, channelization, sub rate, crossover and other functional characteristics to adapt to the energy Internet to provide differentiated services for the power grid end-to-end business, to ensure the reliable, low latency, security transmission of the key businesses, enhance the energy transmission efficiency of energy Internet, also simplifies the mapping relationship between optical transmission network equipment.
