Flex Net Sim is a C++ simulation library for developing allocation algorithms in flexible grid optical networks. It supports Elastic Optical Networks (EONs), Multi-Band EONs (MB-EONs), and Spatial Division Multiplexing EONs (SDM-EONs), enabling flexible network customization. Using a Poisson-based traffic model, it lets researchers focus solely in the algorithm codification without handling the simulation infrastructure.
