Disclosed is a dynamic data stream scheduling method of a data center based on a hybrid transmission mode. The dynamic data stream scheduling method of the data center based on the hybrid transmission mode comprises, in a data center network based on the hybrid transmission mode, taking the volume of a data stream, a network topological graph formed by connecting switches in a wired mode, an interference graph formed by connecting the switches in a wireless mode and available wireless connection at input, solving a data stream scheduling problem by integrating the methods of relaxation algorithm, linear programming and the like, and lastly, obtaining a data stream transmission route and link service conditions as algorithm output. By reasonable scheduling mass data streams in the data center, the dynamic data stream scheduling method of data center based on the hybrid transmission mode eliminates the hotspot problem of the data center, solves jamming and improves the integral performance of the data center can be improved; meanwhile, the dynamic data stream scheduling method of data center based on the hybrid transmission mode can control the consumption within a certain range and accordingly avoid introducing new burdens to the data center. The dynamic data stream scheduling method of data center based on the hybrid transmission mode can reasonably schedule mass data streams in a network, eliminate hotspots and jamming of the data center network and improve the performance of the data center.
