Embodiment

[0049] In order to better illustrate the content of the present invention, a detailed description will be made in conjunction with the actual topology visualization process:

[0050] The main content of step (1) is to generate the latitude and longitude data of each autonomous domain and calculate which top-level autonomous domain is closest to the autonomous domain except Tier1 and Tier2.

[0051] Step (1.1) is to generate the latitude and longitude data of each autonomous domain. Use the geolocation database (ip2Location) to query the latitude and longitude data of all the prefixes declared by each autonomous domain, and combine and arrange to obtain the latitude and longitude list data of the autonomous domain. The resulting data looks like this:

[0052]

[0053] The above data is information (part) of autonomous domain No. 7029. The data separated by "|" are the autonomous domain number, autonomous domain name, country, autonomous domain size, longitude information lis...

Abstract

An autonomous domain-level Internet topology visualization method relates to the technical field of network topology visualization. In order to solve the problem that the existing Internet topology visualization methods cannot reflect the topology characteristics of the autonomous domain level. According to the hierarchical information, autonomous domains are divided into Tier1, Tier2 and other autonomous domains; all autonomous domains in Tier1 are represented by a graphic symbol, all autonomous domains in Tier2 are represented by the same or different graphic symbols from Tier1, and the remaining autonomous domains Domains are represented by graphical symbols different from Tier1 and Tier2; the longitude coverage in the geographic information is counted to obtain the longitude coverage of the autonomous domain, and the longitude coverage of the autonomous domain is used as the abscissa data of the autonomous domain-level Internet topology map; Use a graphics drawing tool to generate a two-dimensional map with longitude as the abscissa and topology level as the ordinate. The two-dimensional map reflects the basic information and adjacency information of the autonomous domain, thereby completing the visualization of the Internet topology at the autonomous domain level.

Description

technical field [0001] The invention relates to an autonomous domain-level Internet topology visualization method, and relates to the technical field of network topology visualization. Background technique [0002] Autonomous domains are one of the key elements of the Internet routing architecture. Large-scale routing such as transnational routing inevitably uses interdomain routing. Autonomous domains play an important role in Internet routing. Therefore, it will be convenient to visualize the Internet topology at the autonomous domain level. We understand and master autonomous domains. Moreover, the distribution of the global Internet at the autonomous domain level is uneven, and the number and scale of autonomous domains in different countries and regions vary greatly. The visualization of the autonomous domain-level topology helps to recognize the gap in Internet construction at the national level. [0003] Most of the existing routing visualization technologies represe...
