国家网络与运营商网络的一致性分析

In the context of cyberspace sovereignty, there is an inconsistency between the National Network divided by national sovereignty and the national Operator’s Network divided by network ownership. To study the deployment of the National Network and Operators’ Network in various countries around the world, this paper proposes a consistency analysis method for the National Network and Operator’s Network from the perspective of network topology measurement data. First, a heuristic method based on router constraints is used to annotate the nation and operator where the topology data is located and a national-level “jurisdiction-ownership” data set of global routers is extracted. Secondly, the consistency index between the National Network and Operator’s Network based on the similarity rate and the external ratio difference is proposed, and quantitative analysis is carried out from the multi-dimensional network and border, router and link, and a consistency index between the National Network and the Operator’s Network of each nation in the world is obtained. Finally, the deployment status of Internet infrastructure in different nations is studied in terms of the deployment scale, scope, and consistency. The experimental results show that the coverage of the router constraint-based heuristic method for annotating topological data is 99.12%, and the accuracy of annotated geographic countries and operator’s countries is 96.47% and 75.08%, respectively, as verified by IXP. Among the 187 sovereign countries in the world covered by the topology data, the average internal similarity between the National Network and Operator’s Network is 0.66, with 106 countries above the average, and the average external ratio difference is 0.15, with 121 countries below the average. The vast majority of countries have higher consistency in routers and links in the network than in border routers and links. 95 countries have higher consistency. A few nations have most of the resources of the global Internet and are closely associated with the Internet infrastructure of many nations, for example, the United States has 39.2% of the total number of global routers, which are deployed in 111 nations, while 109 nations have routers deployed in only 5 nations or less. The number of internet infrastructures distributed in other countries such as China, Israel, the United States, the United Kingdom, and Norway far exceeds the number deployed in their own territories, while nations such as Japan, Mexico, Finland, and Germany do the opposite.
