摘要
针对时间触发以太网的信息网络能够满足高带宽、低延迟、高可靠的应用需求,文章提出了一种兼容传统以太网,实现关键流量降级传输的以太网接口设计方案,并完成接口逻辑实现。文章对数据帧的发送延迟、接收延迟等主要指标进行了仿真和实物测试,最后与1553B总线进行了对比,结果表明该接口能够满足当前飞行器数据传输要求,可以应用于面向空间应用的各类高带宽、低延迟、高可靠数据传输场景。
Aim at time triqgered Ethernet,it can meet the application requirements of high bandwidth,low latency,and high reliability.This paper proposes a design scheme for a time triggered Ethernet interface that can be compatible with traditional Ethernet and achieve degraded transmission of critical traffic.The implementation of the time triggered Ethernet interface has been completed,and key indicators such as data frame transmission and reception delay have been simulated and tested.Finally,a comparison has been made with bus of 1553B,the results indicate that this interface can meet the current requirements for space data transmission and can be applied to various high bandwidth,latency,and high reliability data transmission scenarios for space applications.
