Data frame sending method and apparatus

A data frame sending apparatus, comprising:

• a processor configured to:
• acquire a basic speed set,
• determine a current sending speed, wherein the current sending speed is an element with a maximum speed in a candidate speed set, wherein the candidate speed set is a set of elements that are in the basic speed set, and wherein a packet sending success rate is greater than or equal to a packet sending success rate threshold;
• acquire an aggregation length value according to the current sending speed, wherein the aggregation length value is a maximum length of a frame that can be sent at the current sending speed;
• determine multiple medium access control protocol data units (MPDUs) from to-be-sent MPDUs according to the aggregation length value;
• aggregate the multiple MPDUs to obtain an aggregate MPDU (A-MPDU), wherein a length of the A-MPDU is less than or equal to the aggregation length value;
• add a first value to the packet sending success rate of the current sending speed when the A-MPDU is sent successfully;
• add a second value to the packet sending success rate of the current sending speed when a quantity of sending failures for sending the A-MPDU is less than a failure quantity threshold, wherein the first value is greater than the second value, wherein an initial value of the packet sending success rate of the current sending speed is an upper limit value, and wherein the packet sending success rate of the current sending speed after being added with the first value does not exceed the upper limit value;
• subtract a third value from the packet sending success rate of the current sending speed when the quantity of sending failures for sending the A-MPDU is equal to the failure quantity threshold;
• and
• a wireless network interface coupled to the processor and configured to send the A-MPDU at the current sending speed.
