N2 - Software-defined networking (SDN) brings new opportunities in the design of more reliable and flexible consistent network update mechanisms by making the update process independent of the underlying routing protocols. With the advance of wireless transmission technology, more and more enterprises have deployed wireless antennas into their data centers. However, to the best of our knowledge, none of the state-of-the-art solutions consider radio interference and resource competition into their model design of consistent network update. In this paper, we first propose a wireless dependency model to formulate radio interference. Based on traffic delivery and resource constraints, we formulate the resource competition problem as an update time minimization problem for ensuring the consistency properties, and then propose a greedy-heuristic scheme to minimize the total update time. Simulation results show that the proposed scheme is efficient and outperforms a well-known solution designed for network update in SDN. The simulation results also reveal the importance of resolving resource competition during network update.
