本章讨论了确定性以太网的结构，它有助于提高时间关键通信系统中服务的安全性和可访问性。帧交换是将帧连接到其目的地的方法。混乱的帧交换网络会增加应用程序响应时间的波动，并在敏感网络中造成弱点。动态帧流量振荡通过隔离中断网络服务的外部影响，使帧工作负载更有组织和更易于管理。这个概念，我们称之为关键网络，组织网络并减少网络资源浪费，例如开销，从而通过仔细规划帧传输的类型和可用的网络资源来减少应用网络帧延迟。帧流量由网络流量振荡器（NTO）处理，NTO在帧传输中创建确定性时间响应。这两个概念在组合时消除了在帧中分配任意优先级编号的需要，并且消除了连续应用传输的开销，并且隐藏了每个帧内的敏感开销信息。这个概念是用一个机场场景中的实时交通模拟来说明的。
This chapter discusses the structure of deterministic Ethernet which helps to improve the security and accessibility of services in a time critical communication system. Frame switching is the method of connecting frames to their destination. A disorganised frame switching network increases the fluctuation of application response times and creates weakness in a sensitive network. Dynamic frame traffic oscillation allows the frame workload to be more organised and manageable for networking by isolating external influences that disrupt network service. This concept, which we term Critical Networking, organises networks and reduces network resource wastage, such as overheads, thereby reducing application network frame delay by carefully planning the type of frame transmission and the available network resource. The frame traffic is handled by a network traffic oscillator (NTO), which creates deterministic time response in frame transmission. Both concepts when combined remove the need to assign arbitrary priority numbers in frames, and overheads for consecutive application transmissions and hides sensitive overhead information within every frame. The concept is illustrated using a simulation of real-time traffic in an airfield scenario.
