摘要
航空电子全双工交换以太网(Avionics Full Duplex Switched Ethernet,简称AFDX)是一种标准以太网子集,仅支持10/100Mbps传输;近年来,为满足机载网络对带宽的逐渐增长的需求,千兆AFDX网络技术研究渐渐展开;着重研究千兆AFDX网络物理层和介质访问控制(MAC)层,设计出一种支持多种传输介质、三种速率的千兆AFDX网络测试卡,使用成熟测试卡APX-GNET-4验证其功能正确性,为分析千兆AFDX网络的技术参数和虚拟链路VL、冗余等规则、研制和测试新产品提供技术基础。
Avionics Full Duplex Switched Ethernet （AFDX） is a subset of standard ethernet, which supports transport at 10/100 Mbps. Recently, study of Gigabit AFDX Network has started because Aircraft Network need a higher bandwidth. Based on the study of Physical Layer and Medium Access Control Layer of Gigabit AFDX Network, design a type of Gigabit AFDX Network testing card, and verify its function correctness with mature testing card APX GNET--4. It can analyse the technology parameters of Gigabit AFDX Network and rules of Virtual Link （VL） and redundancy management, which provides technology for designing and testing new products.
