This document summarizes a research paper on virtual network recognition and optimization in an SDN-enabled cloud environment. The paper proposes using SDN and cloud computing technologies to increase the functionality and capacity of wireless networks. It formulates an online routing problem to maximize traffic flow over time while meeting constraints. A fast approximation algorithm is developed based on time-dependent duals. Extensive simulations show the algorithm outperforms heuristics by enabling end-to-end optimization and awareness of congestion and budgets. The paper concludes SDN is still emerging but highlights areas of expanding its scope and applications.
