【摘要】：在航空航天系统中，要实现信息的传输，信息交换是关键技术之一。近年来，以太网技术发展迅速，分组交换因此得到了广泛应用，但是传统的以太网交换单元并不适宜直接应用于航空航天系统中，而必须针对特殊应用开发具有特殊功能保证的专用交换单元。本文结合实验室承担的项目“专用交换单元的设计与实现”。首先，在分析了设计需求的基础上，简要介绍了专用交换单元的总体结构及其主要子模块的功能，并通过详细分析提出了性能改进的实现方案；其次，提出了一种流分类设计方案，可实现数据流的快速过滤及黑白名单管理。第三，设计了一种分组处理机制，实现了数据分组在二层及三层的高效处理与转发。最后，搭建测试平台，对专用交换单元进行了系统级测试，，并总结了测试过程中所遇问题及解决措施。测试结果表明所设计的流分类及分组处理运行正确，性能良好，能够满足专用交换单元的设计需求。
[Abstract]:In aerospace system, information exchange is one of the key technologies to realize information transmission. In recent years, with the rapid development of Ethernet technology, packet switching has been widely used, but the traditional Ethernet switching unit is not suitable for direct application in aerospace systems. Special switching units with special function guarantee must be developed for special applications. This paper combines the project "Design and implementation of Special switching Unit". Firstly, based on the analysis of the design requirements, the general structure of the special switching unit and the functions of its main sub-modules are briefly introduced, and the implementation scheme of performance improvement is put forward through detailed analysis. A design scheme of stream classification is presented, which can realize fast filtering of data stream and management of black-and-white list. Thirdly, a packet processing mechanism is designed to efficiently process and forward data packets in layer 2 and layer 3. Finally, the test platform is set up, the system level test of the special switch unit is carried out, and the problems encountered in the testing process and the solutions are summarized. The test results show that the designed stream classification and packet processing are running correctly and the performance is good, which can meet the design requirements of the special switching unit.
