基于BPF包过滤机制的数据采集系统的设计与实现

Design and Implementation of Data Collecting System Based BPF Architecture

为了捕获校园网中访问各个数据库检索系统的数据包,利用BPF包过滤机制、以太网的广播传输特性等技术设计和实现数据采集系统。同时为了提高了系统的效率,还引入多线程技术,使得数据采集系统在同一时刻既能采集数据包又能实时处理数据包并写入后台数据库中。

To capture all packets of network, this paper designs and implements a data collecting system based BPF architecture. Several realization technologies are adopted, which are the broadcast characteristic and multi-thread policy, etc. The multi-thread policy can improve the performance of the data collecting system. With it, data collecting system can both captures packets and sents them to database at the same time.
