The invention discloses an end-to-end time delay guarantee transmission scheduling method oriented to an industrial backhaul network. The end-to-end time delay guarantee transmission scheduling method oriented to the industrial backhaul network comprises the two processes of a concentrated time delay distribution process and a segmented time delay guarantee forwarding process. The distribution method comprises the steps that a time delay distribution value of each segment link is calculated by a network manager according to time delay requests and transmission path loading conditions of a business flow, and the time delay requests and business header information are sent to network switches. The forwarding of data business is achieved by the network switches according to the time delay requests of specific business, wherein firstly, business data are placed in a corresponding delay priority buffer queue; then, the data in the time delay priority buffer queue are sent to a Crossbar switching matrix by the corresponding network switch through an experiment priority scheduling mechanism; finally, the timely transmission of the business in the corresponding buffer queue is guaranteed by the adoption of a Crossbar scheduling mechanism. According to the end-to-end time delay guarantee transmission scheduling method oriented to the industrial backhaul network, the fine-grained time delay control mechanism is adopted, so that the supportability and the determinacy of the business end-to-end time delay are improved.
