Design and Implementation of PCIe Interface Card Based on Gigabit AFDX TAP

摘要:

近年来,大通信量使得机载网络对带宽的需求逐渐增长,目前的10/100 Mbps传输速率已经不能满足需求,故千兆AFDX技术研究急需开展；基于千兆AFDX网络,对TAP卡设计和实现进行了研究；通过系统设计和详细设计对设计过程中的问题进行分析,提出了一种基于FPGA的TAP卡设计方法；模拟不同的网络情况对设计进行了验证；结果表明该设计可以正确反映网络细节,能够给网络级调试带来了极大的便利。

Abstract:

In recent years, the mass communication makes the airborne network bandwidth on demand is increasing, the 10/100Mbps transmission rate is already unable to meet the demand, so the Gigabit AFDX technology research is urgently needed. The design and implementation of TAP based on the research of Gigabit AFDX network. Through analyzing the design process of system design and detailed design analysis, put forward a design method of FPGA based TAP card. The verification of the design to simulate different network environment. The results show that the design can accurately reflect the details of the network, can bring great convenience to the network level debugging.
