AFDX是双余度、可确定的数据传输网络。 TAP卡是将设备接入网络中，在保证原来的双向通信正常进行的同时，将原来两个方向的数据分别复制一份输出到TAP端口上。为了研究AFDX网络特性，对AFDX网络的数据和流量进行监控与分析。文中介绍了AFDX网络基本特性，重点描述了AFDX网络TAP卡的设计实现。该TAP卡利用标准的以太网PHY接入AFDX网络，通过FPGA逻辑对接收到的网络数据进行存储，并通过USB接口上传给主机软件。测试结果表明，该TAP卡能够在不影响网络传输的前提下，正确全面地对AFDX网络的数据进行监控。

AFDX is a data transmission network with redundancy and determinism. TAP is accessed to network without intervening the two-way data transmission. It copies the data from on way to another. In order to study the features of AFDX network,monitor and ana-lyze the data and flow of AFDX network. Describe the basic features of AFDX network,mainly the design and implementation of TAP of AFDX network. The TAP accesses to AFDX with standard Ethernet PHY,stores frames received from AFDX with FPGA logic,and sends frames to host software with USB interface. Tests show that the TAP can monitor AFDX network data without interfering the network transmission.
