We present a novel approach to analyzing and planning photonic communication networks using concepts from statistical physics and information theory.

Communication networks play a crucial role in modern life infrastructure. When planning and operating such a network, resilience in case of failures as well as costs of infrastructure have to be taken into account. Classical network design algorithms are based on integer linear programming and are located well within the non-polynomial complexity realm.

To achieve a nearly optimal combination of resilience and cost efficiency, we use the topological analysis of neighbourhood graphs and a maximum entropy routing and spectrum assignment strategy. Combining the topological characteristics with the dynamic load properties under maximum entropy distribution we achieve a highly fault resistant as well as cost optimized fiber network.
