千兆网络数据包分析过滤采集系统设计

Design and analysis of filtering and acquisition system of gigbit network

介绍了基于高性能FPGA的千兆网络数据分析过滤采集系统设计。该系统能够对千兆主干网的网络数据进行分析,过滤和采集。该系统提供良好的配置接口,并将所关心的数据转发,百分比采样或是抛弃。而且能够对报文进行统计,并按照协议类型,源地址,目的地址等规则将数据包分类存储起来。本系统采用硬件查找方式进行数据包的分类极大地加速了数据包分类的速度。

This thesis introduces the filter acquisition system of data analysis based on the gigabit network of high performance FPGA.This system has an ability of data analyzing,filtering and gathering for the gigabit backbone network.It not only provides well configuring interface,and transfers the related data as well as the percentage of sampling,or abandons,but also gives the statistics for packets and stores the classification data according to the rules of protocol type,source address and destination address.The system uses the way of hardware checking for packet classification,and it greatly accelerates the speed.
