摘要
在对Linux系统捕包机制分析的基础上,通过试验详细讨论了高速网络环境下网络捕包的性能瓶颈。针对性能瓶颈给出了NAPI与内存映射机制相结合的改进方案。
Passive packet capture under high traffic load network will lead to NIC interrupt frequently. In this paper, an explanation for the poor performance of packet capture under heavey load is presented. A approach is proposed to decrease the number of NIC interrupt that NAPI mechanism for linux-based systems is taken.
