基于多核网络处理器平台的Libpcap性能评估

he network intrusion detection system is based on the mechanism capturing network packets. Libpcap is one of the most popular packet capture library of the Linux operating system. In this paper, the working mechanism of Libpcap based on the Linux platform is analyzed in detail. In addition, building the experiment environment to test the performance of the typical multi-core MIPS network processor platform and multi-core X86 processor platform in high-speed network environment when capturing packets by Libpcap, finally come to obtain and analyze results of the test.
