A distributed and layered skeleton has been presented, which can be deployed over all the country easily. The monitor and management system can recognize the illegal information and automatically take action according the analysis result. As a sample, an illegal VPN(Virtual Private Network) monitor and management system have been implemented based on Linux, which can dynamically find illegal IPSec tunnels and then filter them.展开更多
