Region-level network survivability difference assessment method and device based on topology analysis

Abstract

The invention provides a regional-level network survivability difference assessment method based on topology analysis, and relates to the technical field of computer network measurement, and the method comprises the steps: calculating survivability sampling of an important autonomous system (AS) in each area; converting the survivability sampling of the important AS in the area into area survivability sampling by up-sampling; creating a significance tester, accessing area survivability sampling from the overall level and the fluctuation level to acquire area survivability ranking; and clustering the area survivability ranking result from the overall level and the fluctuation level to obtain an area survivability clustering result. According to the scheme, the survivability difference of the areas can be evaluated from the overall level and the fluctuation level, universality is achieved, and the essential difference of topology between the areas can be found.

Description

technical field [0001] This application relates to the technical field of computer network measurement, and in particular to a method and device for assessing regional network invulnerability differences based on topology analysis. Background technique [0002] The increasing importance of the global Internet makes it one of the key infrastructures that people rely on in all aspects of life. Network security is the basis for ensuring normal communication. [0003] At present, the Internet topology of a region or region is subject to various security threats. First of all, various types of malicious actors, such as hackers and terrorists, will aim at network topology weaknesses, destroy and intercept Internet traffic, and attack the network to achieve various political, economic or military goals. For example, common DDOS attacks can paralyze the communication infrastructure. [0004] Secondly, existing studies have found that some regions or regions may be disconnected fro...

AI Technical Summary

Problems solved by technology

[0008] For this reason, the first purpose of this application is to propose a method for assessing regional-level network invulnerability differences based on topology analysis, which solves the problem that Internet topology differences in various regions are very different, resulting in the invulnerability of Internet topology in various regions / regions. For problems with differences, reasonably evaluate the invulnerability of regional topologies universally, and get the ranking of regional invulnerability, which is conducive to fully understanding the Internet and is of great significance to improving the security of Internet topology
