【摘要】：在航空航天系統(tǒng)中，要實(shí)現(xiàn)信息的傳輸，信息交換是關(guān)鍵技術(shù)之一。近年來(lái)，以太網(wǎng)技術(shù)發(fā)展迅速，分組交換因此得到了廣泛應(yīng)用，但是傳統(tǒng)的以太網(wǎng)交換單元并不適宜直接應(yīng)用于航空航天系統(tǒng)中，而必須針對(duì)特殊應(yīng)用開(kāi)發(fā)具有特殊功能保證的專用交換單元。 本文結(jié)合實(shí)驗(yàn)室承擔(dān)的項(xiàng)目“專用交換單元的設(shè)計(jì)與實(shí)現(xiàn)”。首先，在分析了設(shè)計(jì)需求的基礎(chǔ)上，簡(jiǎn)要介紹了專用交換單元的總體結(jié)構(gòu)及其主要子模塊的功能，并通過(guò)詳細(xì)分析提出了性能改進(jìn)的實(shí)現(xiàn)方案；其次，提出了一種流分類設(shè)計(jì)方案，可實(shí)現(xiàn)數(shù)據(jù)流的快速過(guò)濾及黑白名單管理。第三，設(shè)計(jì)了一種分組處理機(jī)制，實(shí)現(xiàn)了數(shù)據(jù)分組在二層及三層的高效處理與轉(zhuǎn)發(fā)。最后，搭建測(cè)試平臺(tái)，對(duì)專用交換單元進(jìn)行了系統(tǒng)級(jí)測(cè)試，，并總結(jié)了測(cè)試過(guò)程中所遇問(wèn)題及解決措施。測(cè)試結(jié)果表明所設(shè)計(jì)的流分類及分組處理運(yùn)行正確，性能良好，能夠滿足專用交換單元的設(shè)計(jì)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.
