D2.4. Techno-economic analysis and network architecture refinement

This deliverable will summarize the techno-economic analyses performed in WP2, considering the candidate architectures, and exploiting the developed network design methodologies. Based on these analyses and taking into account the progress done in both WP3 and WP4, it should also propose further network architecture refinements. If possible, it should also provide a roadmap for the adoption of specific technologies and architectures to fulfil the METRO-HAUL objectives.
