Method and apparatus for controlling data packet sending, model training method and apparatus, and system

An apparatus for controlling data packet sending, comprising:

• a memory and a processor, wherein the memory is coupled to the processor;
• and
• the memory stores program instructions, and when the program instructions are run by the processor, the processor is configured to:
• obtaining a plurality of control models, wherein 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, wherein the first condition is used to indicate a congestion control requirement of the first application, the first control model is used to process a transmission parameter of any network in at least one network, to obtain a control parameter required for sending a data packet of the first application by using the any network, the at least one network comprises a first network accessed by the end node, the control parameter is used to control sending of the data packet of the first application, so that the any network meets the congestion control requirement of the first application, and the control parameter comprises at least one of a congestion window value or a transmit rate;
• processing, by using the first control model, a transmission parameter of the first network accessed by the 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.

A non-transitory computer-readable storage medium, storing one or more instructions that, when the medium is in an apparatus for controlling data packet sending, executed by at least one processor, cause the at least one processor to:

• obtain a plurality of control models, wherein the plurality of control models corresponds to a plurality of conditions;
• select, based on a first condition, a first control model corresponding to the first condition from the plurality of control models, wherein the first condition is used to indicate a congestion control requirement of the first application, the first control model is used to process a transmission parameter of any network in at least one network, to obtain a control parameter required for sending a data packet of the first application by using the any network, the at least one network comprises a first network accessed by the end node, the control parameter is used to control sending of the data packet of the first application, so that the any network meets the congestion control requirement of the first application, and the control parameter comprises at least one of a congestion window value or a transmit rate;
• process, by using the first control model, a transmission parameter of the first network accessed by the 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
• control sending of the data packet of the first application based on the first control parameter.
