Internet上面部署的各种各样的防火墙给网络拓扑检测工作带来了很大的困难。通过对防火墙的安全规则进行分析,本文提出了多协议活节点探测方法和多协议网络路径检测方法,从而形成了一套系统的针对防火墙干扰的网络拓扑检测方法。
A variety of firewalls deployed on the Internet have caused great difficulties in network topology detection. By analyzing the security rules of the firewall, a multi-protocol active node detection method and a multi-protocol network path detection method are proposed in this paper, which forms a set of system network detection methods for firewall interference.
