The Design Of Network Data Management Hardware Platform Based On FPGA

With the rapid development of information technology such as cloud computing,Internet of Things,and big data,people are becoming increasingly dependent on various network terminal equipment,and the network data environment in communities,enterprises,schools and other scenarios is becoming more and more complex.Network security issues such as data leakage,DDo S attacks,and home camera intrusion have become increasingly prominent as lacking of monitoring and management of network data.Meantime,traditional network data monitoring and management solutions based on software have limitations in processing capabilities,processing delays,and resource consumption.Combining research application scenarios and project requirements,this thesis independently designs and implements a set of FPGA-based hardware platform for building network data.The system architecture,processing capacity,processing delay,scalability,and resource occupancy rate and other aspects are well-rounded revamping on condition that meeting project requirements.The network data management hardware platform is a self-designed 12-layer circuit board,using Xilinx's Kintex FPGA chip and Zynq So C chip as the core processor.Main peripherals and interfaces contains 3 groups of 12 DDR3 memory particles,1 PCIe Gen2.0 x8 interface,two SFP+ 10 Gigabit Ethernet ports,and three10/100/1000 M adaptive network ports.1871 electronic components,1187 signal netlists,5922 signal connections and 27 power supplies are combined into the whole board,and the highest signal rate can reach 10.3125 Gbps.This thesis combines theoretical analysis and simulation verification,strictly restricts the PCB layout design,and finally overcomes the signal integrity,power integrity and electromagnetic compatibility issues in the high-speed digital system.Then,the design of the hardware platform is completed.Based on this hardware platform,this thesis also independently develops hardware logic and software systems.In the hardware logic part,functions such as network data forwarding and filtering,network data flow statistics,abnormal data detection and capture are realized in FPGA through the Verilog HDL hardware programming language.The software system development part completes the design of data transmission and storage,visual interface and PCIe driver,based on C language,Node JS,Windriver and other languages or platforms.In summary,this thesis has completed the design of network data management hardware platform,FPGA programmable logic design,and host computer software design.It provides solutions for network data monitoring and management problems in application scenarios such as communities,enterprises,schools,etc.,and has strong scalability and broad application prospects.
