The Internet was originally shaped as a fully decentralized, cooperative packet transport system that offered transmission services to those who were willing to inter-connect. Its scalable architecture aimed at supporting a global information infrastructure without the requirement of national contributions, regulations or governmental support. Meanwhile the Internet has matured to an almost mission-critical infrastructure for global communication, but also for enabling key operations of public administration and business affairs, of research, education, and entertainment within individual countries.
In this project, we identify, characterize and visualize the fraction of the Internet that serves as the nation-centric communication system of Germany. Starting from the RIPE database and harvesting several additional databases, route monitors and Internet measurement projects, we extract the minimal routing graph that interconnects all members, as well as a subset of relevant players within the German Internet.
The research in this project includes:
- Identifying Autonomous Systems at the nation-state level
- Classifying networks with national relevance
- Visualizing inter-domain routing
- Analyzing Internet sub-graphs (e.g., country-level routing)
The following Visualizations are available:
- Hierarchical Rings
- Hierarchical Layers
- Hierarchical Rings including Betweeness
- Kamada-Kawai Spring Model
- Communication Flows between Relevant Business and Public Sectors
The following Publications are available:
- Ein Routing-Atlas für die strukturelle und visuelle Exposition des deutschen Internets
- A Framework for Nation-Centric Classification and Observation of the Internet
- Towards a Nation-Centric Understanding of the Internet
- Exposing a Nation-Centric View on the German Internet - A Change in Perspective on the AS Level
