Internet

The internet consists of a physically connected network of autonomous systems. It is a classical information network, build over time to accomodate the needs of different parts of the world to communicate with each other. The structure of the internet is hierarchical, somewhat modular, and to some extent influenced by geographical constraints. The degree distribution of the internet is scale free with an exponent close to 2. Finally it is build over time, influenced by adding new autonomous systems, and also by merging events between old servers. Models of evolution of the internet's structure, as well as information spreading across the internet serve as inspiration to think about other communication networks.
