Abstract:

This paper designs a high speed packets capture platform(HSPCP)for IPv6 high speed environment using the idea of zero copy. It is mainly aimed at solving the serious packets dropping problems in tradition packets capture technology. The platform is based on Intel82541GI's gigabit ethernet driver e1000 to improve the network packets reception process. Through registered a miscellaneous equipment in kernel,it achieves mmap and ioctl methods and we rewrite a user space packets capture program according to the improved zero copy driver. The experiments show that HSPCP in packet capture rate, CPU utilization, the system context switch times have significantly improved than the libpcap capture manner.

Key words: IPv6, packet capture, index terms-zero copy, high speed network
