基于ICMP、UDP、TCP协议的分布式IP级拓扑探测方法

Distributed IP-Level Topology Detection Method based on ICMP,UDP and TCP Protocols

网络拓扑测量是认识、研究网络空间的基础,因此研究网络拓扑测量技术具有重要意义。随着安全防范意识的提高,基于传统方式的探测手段会导致拓扑中存在大量的匿名路由器,降低拓扑完整性。针对该问题,提出了一种基于Traceroute、ICMP、UDP、TCP协议的分布式IP级互联网拓扑探测方法。该方法通过在全球范围内部署的分布式探测节点和多种协议组合的方式,不仅能够加快探测速度,而且能最大限度地减少匿名节点的数量,进一步扩充和加强拓扑图,使获得的拓扑图更接近实际。

Network topology measurement is the basis for understanding and exploring cyberspace. Therefore, the research on network topology measurement technology is of great significance. With the improvement of security awareness, the detection means based on traditional methods would lead to a large number of anonymous touters in the topology and the reduction of topology integrity. Aiming at this problem, a distributed IP-level Internet topology detection method based on Traceroute, ICMP, UDP and TCP protocols is proposed. This method could speed up the detection speed and minimize the number of anonymous nodes via the distributed probe nodes and multiple protocols combination on a global scale. Further expansion and enhancement of the topology map would make the obtained topology map closer to the reality.
