基于FPGA的网络监控交换机设计与实现

Design and Implementation of Network Monitoring Switch Based on FPGA

针对传统网络监控交换机在接口密度和处理能力上的不足,该文给出了一种基于FPGA的高密度网络监控交换机设计和实现方法。采用FPGA+Switch的架构,利用FPGA芯片构造接口线卡,通过并行计算技术实现万兆速率下的网络接口适配和数据线速处理。利用Switch芯片构建多线卡的交换连接,极大地提高了网络接口密度。

In view of the shortage of the interface density and processing ability of the traditional network monitoring switches,this paper gives a design and implementation method of high density network monitoring switch based on FPGA.Using the architecture of ＇FPGA＋Switc h＇,the interface linecard is constructed with FPGA chip,the network interface adaptation and the data line rate processing at 10 Gbps are realized by parallel computing technology.Using Switch chip to build switching connection of multiline card greatly improves the density of network interface.
