Data center network multi-path transmission method based on out-of-order tolerance

The invention relates to the technical field of network information, in particular to a data center network multi-path transmission method based on out-of-order tolerance, which comprises the following steps: identifying a data stream and a data stream type according to header information of a data packet, and determining a group interval of the data stream according to the data stream type and a network load, the method comprises the following steps: uniformly grouping data packets in a data stream according to group intervals, calculating queuing time delay of each transmission path, and when each data packet selects a transmission path, firstly excluding the transmission path of which the queuing time delay is smaller than the maximum queuing time delay of the previous group, and then selecting the transmission path of which the queuing time delay is minimum from the remaining transmission paths. According to the method, the data packet is used as forwarding granularity, so that the use efficiency of the l
