N2 - As the advanced development of directional antenna, wireless technique has been introduced into data center networks, denoted as hybrid data center networks (HDCN). HDCN shows its great potential to mitigate the over-subscription problem in higher level links in traditional data centers.However, how to implement network virtualization in HDCN such that all the wireless links can be sufficiently utilized remains a challenging problem. In this paper, we study virtual network embedding problem in HDCN, by jointly considering embedding virtual networks and scheduling the directional antennas. We first summarize this problem intoan integer programming problem, then propose a heuristic algorithm to find a near optimal solution for the studied problem. The simulation based evaluation shows the great efficiency for the proposed algorithm deriving a suboptimal solution in HDCN.
