| 摘 要： | 随着网络速度的不断提高，当前大多数的测量系统已经不能适应高速网络环境而出现数据报文丢失，研究开发适应高速网络环境的测量器已成为当前网络技术的热点之一。该文主要针对基于Linux内核的千兆位网络测量器设计中存在的数据报文丢失率高的问题进行了研究，提出了用户到内核缓冲区映射的方法，有效地解决了该问题。

| Abstract: | Decreasing packet-loss ratio is a key technology in network traffic measurement, current traffic measurement systems can not catch up with the high-speed network, so they represent packets losing. Designing and developing the network meter to adapt high speed network have become the one of the network technique hotspots. Aiming at the high Packet-loss problem which widely exists in 1 000Mbps network Meter based on Linux kernel, this paper puts forwards the measure of buffer mapping from user-space to kernel-space. Practice shows that the measure is so effective in solving packet-loss problem. |
