The invention discloses a wireless data center network topology optimization method and system based on flow prediction. The method comprises the following steps: SS1, employing an input parameter topredict the network business flow in a period time period, and obtaining the data business demand Dsd between different racks in a network; SS2, constructing a network topology with the maximum throughput and the minimum network overhead according to the data service demand Dsd between the different racks in the network obtained in step SS1; and SS3, based on the network topology obtained in stepSS2, sequentially calculating, allocating and establishing a data route for the data flow size request passing through each link. Aiming at the high dynamic property of the data volume of the data center network, an optimization scheme of the data center network topology based on the FSO is researched so as to improve the utilization efficiency of network resources and the throughput of the network. 本发明公开了基于流量预测的无线数据中心网络拓扑
