  • Publication number: 20220286402
    Abstract: A controlling data packet sending method. The method for controlling data packet sending includes: obtaining a plurality of control models, where the plurality of control models corresponds to a plurality of conditions; selecting, based on a first condition, a first control model corresponding to the first condition from the plurality of control models, the first control model is used to process a transmission parameter of any network in at least one network; processing, by using the first control model, a transmission parameter of a first network accessed by an end node, to obtain a first control parameter required for sending the data packet of the first application by the end node by using the first network; and controlling sending of the data packet of the first application based on the first control parameter.
