Flow group scheduling method in photoelectric hybrid data center network

The invention discloses a flow group scheduling method in a photoelectric hybrid data center network, and belongs to the technical field of network transmission. According to the method, firstly, input flow is divided into flow groups according to service semantics, and then a network topology structure is input. Secondly, on the basis of flow group information, solving the sequence of flow groups in combination with the characteristics of port bandwidth and the like of the optical circuit switch and the electric packet switch to obtain an ordered flow group sequence; and finally, scheduling the flow groups and sub-flows contained in the flow groups according to the flow group sequence, optimizing the transmission of the flow in the photoelectric hybrid network structure, reducing the transmission completion time of the flow groups, and achieving the purpose of comprehensively optimizing the overall transmission. According to the method, the scheduling transmission process of the flow in the photoelectric hyb
