To this end, a Workshop on "SDN for Future Networks and Services" (SDN4FNS'13) was organized in Trento, Italy (Nov. 11th-13th 2013). Following the results of the workshop, in this paper, we have further analyzed scenarios, prior-art, state of standardization, and further discussed the main technical challenges and socio-economic aspects of SDN and virtualization in future networks and services. A number of research and development directions have been identified in this white paper, along with a comprehensive analysis of the technical feasibility and business availability of those fundamental technologies. A radical industry transition towards the "economy of information through softwarization" is expected in the near future.}, author = {Manzalini, A and Saracco, R and Buyukkoc, C and Chemouil, P and Kukli{\'n}ski, S and Gladisch, A and Fukui, M and Shen, W and Dekel, E and Soldani, D and Ulema, M and Cerroni, W and Callegati, F and Schembra, G and Riccobene, V and Mas Machuca, C and Galis, A and Mueller, J}, url = {http://sites.ieee.org/sdn4fns/whitepaper/} }
