AFDX exchange method based on time trigger architecture and exchanger

The invention discloses an AFDX exchange method based on a time trigger architecture. The AFDX exchange method comprises the following steps: establishing an information table; searching an information table after receiving the data frame, and taking the receiving verification information, the frame type and the forwarding information of the data frame; distinguishing data frames according to frame types, carrying out receiving and forwarding in a time triggering mode and a flow control mode, and extracting corresponding parameters according to two different forwarding modes. The invention also discloses an AFDX exchanger established according to the AFDX exchange method. According to the invention, the fixed forwarding delay of the data frame in the switch is realized, and the determinacyof network system communication is improved. 本发明公开了一种基于时间触发架构下的AFDX交换方法，包含建立信息表；接收数据帧后查找信息表，取该数据帧的接收校验信息，帧类别以及转发信息；根据帧类别区分数据帧按时间触发方式接收转发和流量控制方式接收转发，同时按照两种不同转发方式提取各自对应的参数。本发明还公开根据上述AFDX交换方法建立的AFDX交换机。本发明实现数据帧在交换机中固定的转发时延，提高网络
