摘要
分析了Linux下基于Libpcap的网络数据包捕获技术机理,指出了影响数据包捕获性能的"瓶颈",通过零拷贝技术、内存映射技术和中断节制机制对其改进,并进行仿真实验。结果表明:改进方法可以显著提高数据包的捕获率。
The technical principle of network data packet capture on Libpcap under Linux is analyzed and the performance "bottleneck" is found.Improvement is made using the technology of zero-copy,memory mapping and interrupt mechanism,and the result of simulation demonstrates that the method can improve the rates of data packet capture.
