Enabling Consistent Network Update in Wireless Data Center

Software-defined networking (SDN) brings new opportunities in 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, increasing enterprise has deployed radio antennas into their wireless data center. However, to the best of our knowledge, none of the state-of-the-art solutions consider radio interference into their model design of consistent network update. When the network resource is deficient, the resource competition phenomenon may occur, which prolongs the total update completion time. In this thesis, the wireless resource dependency model is firstly proposed to handle the radio interference. Then, a greedy-heuristic solution is provided to alleviate the resource competition phenomenon. According to the simulation results, the proposed solution can efficiently complete consistent network update in wireless data center. These results also reveal the importance of solving resource competition during consistent network update.
