摘要
为迎合5G/6G时代人们对数据通信不断增长的需求,针对现阶段超高速以太网多业务支持、速率灵活可变和IP光融合组网的发展趋势,研究了灵活以太网(FlexE)的协议规范,包括FlexE基本结构、开销帧定义和Calendar机制。在此基础上,提出一种将介质访问控制(MAC)层不同速率的用户数据映射至物理层中的功能模型,并研究了一种基于Calendar机制的时隙分配算法。
In order to cater to the growing demand for data communication in the 5G and 6G era, aiming at the development trend of ultra high speed Ethernet multi service support, flexible speed and IP optical fusion networking at this stage, this paper studies the protocol specifications of flexible ethernet(FlexE), including FlexE basic structure, overhead frame definition and Calendar mechanism. On this basis, a functional model for mapping user data of different rates in the media access control(MAC) layer to the physical layer is proposed, and a time slot allocation algorithm based on the Calendar mechanism is studied.
