Abstract

In this work we present a software tool for the planning of multi-layer photonic backbone networks. We consider the Routing and Assignment of Wavelengths problem (called RAW) in the optical layer and include a consideration of the electrical layer. The resulting planning problem is very complex, which can be shown by the fact that already the RAW problem is NP-hard. Our approach for a software architecture embeds heuristic and non-deterministic optimization algorithms in a framework of a Simulated Annealing based optimization method. Furthermore, we try to separate the algorithms from the complex data structure of the network model by providing so called Access Interfaces. Therefore, different algorithms can be added as modules to the optimization environment.
