【摘要】：提出了基于FPGA(Field programmable gate array)的多路千兆以太網(wǎng)信號(hào)的篩選與存儲(chǔ)轉(zhuǎn)發(fā)交換技術(shù),該技術(shù)可以線速處理20路千兆以太網(wǎng)數(shù)據(jù),整個(gè)系統(tǒng)的配置與監(jiān)控都是由嵌入式處理器(Nios)來完成;網(wǎng)絡(luò)數(shù)據(jù)包的篩選主要由專門的硬件-網(wǎng)絡(luò)搜索引擎(Network Search Engine)完成,復(fù)雜協(xié)議分析、高強(qiáng)度的計(jì)算均由FPGA完成,提出了定位FIFO技術(shù),提高了存儲(chǔ)轉(zhuǎn)發(fā)速度,使得主處理器能夠?qū)⒏嗟木Ψ旁跀?shù)據(jù)處理與協(xié)議分析上面,從而大大提高了系統(tǒng)的效率;最后給出了整個(gè)系統(tǒng)的測試方法和實(shí)驗(yàn)結(jié)果,結(jié)果證明系統(tǒng)完全可以實(shí)現(xiàn)20路以太網(wǎng)信號(hào)的篩選與存儲(chǔ)轉(zhuǎn)發(fā)交換。
[Abstract]:This paper presents the technology of multi-channel Gigabit Ethernet signal selection, storage and forwarding switching based on FPGA(Field programmable gate array). This technology can process 20 Gigabit Ethernet data at line speed. The configuration and monitoring of the whole system is accomplished by embedded processor Nios. The selection of network data packets is mainly accomplished by a special hardware-network search engine named Network Search engineer. The analysis of complex protocols and the calculation of high intensity are accomplished by FPGA. The technology of locating FIFO is put forward, and the speed of storage and forwarding is improved. The main processor can focus more energy on data processing and protocol analysis, which greatly improves the efficiency of the system. Finally, the testing method and experimental results of the whole system are given. The results show that the system can realize 20 channel Ethernet signal filtering, storage and forwarding switching.
