Avionic full-duplex switched-type Ethernet network card and integration method thereof

The invention relates to an avionic full-duplex switched-type Ethernet network card and an integration method thereof. Allocation information of various layers and a communication interface, required by a terminal system, is downloaded into an RAM (Random Access Memory) in an FPGA (Field Programmable Gate Array) chip, and all functional modules are in circuited connection with the communication interface, therefore, four protocols of a transmission layer UPD, a network layer IP (Internet Protocol), a link layer Virtual Link and a physical layer PHY are integrated on a board card. The invention finishes most functions of the whole AFDX (Avionic Full-duplex); the functions of a soft part are achieved just by simply writing data and ports into a transmission sharing memory of the network card and reading the data and the ports from a reception sharing memory, which is not basically relational to a communication protocol and very simple in operation. The invention can be directly applied to a data loading system of an AFDX bus, an AFDX simulation system, an AFDX integration system, and other application systems.
