Embodiment Construction

[0034] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0035]The present invention analyzes 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 captured routing messages, and extracts these IP addresses according to IP address distribution strategies. The IP subnet is inferred from the information and Traceroute information, and then the IP alias analysis based on graph analysis is performed on Traceroute according to the obtained IP subnet, 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 judgment is established, we compare it with the subnet extracte...

Abstract

The invention discloses an analysis method for alias of a router based on routing information and Traceroute information. The method comprises the following steps of S1, collecting a routing message and Traceroute data in a measured network; S2, extracting an IP address and an IP subnet in the routing message, and inferring an IP alias; S3, analyzing the Traceroute information, and the IP addressand the IP subnet extracted in the step S2 according to an IP address distribution strategy, and inferring the IP subnet in the measured network; S4, inferring the IP alias by using an alias analysistechnology based on graph analysis; and S5, integrating the IP addresses with alias relations to acquire an actual node of the measured network. According to the method provided by the invention, therouting information is integrated into a traditional graph analysis method, the IP address, the IP subnet and the IP alias are extracted by using the routing information, and the extracted informationis used for inferring the IP subnet and recognizing the IP alias, so that the defect that the information acquired by only depending on Traceroute is incomplete is made up, accuracy and coverage of alias analysis are greatly improved, and the alias analysis efficiency is also improved.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a router alias analysis method based on routing information and Traceroute information. Background technique [0002] With the rapid development of modern social network, the scale of the network is constantly expanding, and the structure of the network is becoming more and more complex. The overall topology of the network is of great significance for strengthening network management and control, guiding network design, and optimizing network performance. [0003] In any network, routers are responsible for receiving and forwarding network traffic. In order to ensure network connectivity and save costs, routers generally have more than two network interfaces to connect with other routers. Each interface of a router has an IP address, and each IP address can represent its router, and the IP addresses of each router are mutually aliased. [0004] In traditional network topo...
