Embodiment Construction
[0034] The technical solutions of the present invention are further described below with reference to the accompanying drawings.
[0035]The invention parses router aliases based on routing information and Traceroute information, that is, extracts IP addresses, IP subnets and IP aliases in the network under test by analyzing the captured routing packets, and extracts these according to the distribution strategy of IP addresses. Then, according to the obtained IP subnet, the IP alias analysis based on graph analysis is performed on Traceroute, and finally the IP addresses with alias relationship are aggregated to obtain the actual network nodes in the network. In the subnet inference process, the influence of the IP subnet extracted from the routing information on the IP subnet inference process, that is, when each subnet is judged to be true, we will compare it with the subnet extracted from the routing information. , if the inferred subnet really includes the subnet in the la...
