| With the rapid development of aerospace technology and the increasing complexity of electronic devices, the transmission of information has become more and more frequent exchange has played an important role in it. This thesis is based on a research program "Design and Implementation of Private Switch in Aerospace". According to the requirements of the project, the key technologies of packet processing and transformation talble which support both Ethernet and AFDX are focused on in this thesis.This thesis introduces the research background, Ethernet switching and AFDX technology firstly. Secondly, according to functional and performance requirements of the project, practical implementation is given and design of the structure and function of each module are described overall. Third, detailed design and implementation of packet processing and transformation talble which bases on VLAN technology are discussed. Fourth, the main modules are simulated by the Modelsim software. Finally, The test platform for board-level testing are built and the testing problems are analysed. At present, the design has been verified by board level, indicating that the design is reasonable and meets design requirments. |
