Qing Jiang · Communications technology · 2009
This paper describes a data acquisition system based on bridge.By analyzing traditional structure of network data acquisition system,according to the deficiency of the existing structure,an modified and optimized system structure is proposed,and the zero copy of data is implemented by Netfilter frame in Linux kernel.Experiments prove that the performance of in network content audit system has been remarkably improved.
