1. A service flow scheduling method, applied to a first network device, the method comprising:
separately scheduling a first service flow and a second service flow based on a hierarchical quality of service (HQoS) model, wherein a priority of the first service flow is higher than a priority of the second service flow; and
adjusting, to a first threshold, a transmission rate threshold of the HQoS model for the second service flow when transmission quality of the first service flow does not meet a service level requirement corresponding to the first service flow, wherein the first threshold is less than a current data transmission rate of the second service flow;
wherein the first network device is connected to a terminal through a second network device; and the HQoS model comprises: a first-level scheduler corresponding to a downlink port of the first network device, a second-level scheduler corresponding to a downlink port of the second network device, a first underlying scheduler configured to transmit the first service flow through the downlink port of the second network device, and a second underlying scheduler configured to transmit the second service flow through the downlink port of the second network device; and
wherein a sum of a transmission rate threshold of the first-level scheduler for the first service flow and that of the first-level scheduler for the second service flow is less than or equal to a maximum bandwidth of the downlink port of the first network device; and a sum of a transmission rate threshold of the second-level scheduler for the first service flow and that of the second-level scheduler for the second service flow is less than or equal to a maximum bandwidth of the downlink port of the second network device.
