Abstract: The difference of Linux software routing performance under different environments,and the packet loss causes under heavy load network are analyzed by Netfilter workflow and specific experiments.The Linux kernel and the Netfilter module adjustment method under a larger network for data traffic are presented.The performance of Linux in the data forwarding has greatly improved.And the results provide basis for the Linux routing applications and the future.

Key words: Linux routing, performance of Netfilter, data forwarding performance, kernel debugging

摘要: 从Netfilter工作流程和具体实验,分析不同环境下Linux软路由的各方面性能差异,以及大负荷网络环境下数据包丢失的原因,提出针对数据流量较大的网络环境下Linux内核及Netfilter模块的调整方法。改进后的Linux在数据转发性能上有较大提高,分析结果为Linux软路由的应用前景提供了依据。
