Method and apparatus for adjusting data sending rate of terminal

A device, comprising:

• a memory, at least one processor, and a communications interface being connected by using a bus;
• the memory is configured to store computer-executable instructions;
• and
• the at least one processor is configured to invoke the instructions stored in the memory to perform a method, the method comprising:
• when determining that a return time of feedback information of a first data packet has timed out, reducing a data sending rate of a connection to which the first data packet belongs from a first value to a second value, wherein the first data packet is a data packet sent by the terminal to a target device over a communications link that comprises a wireless link and a wired link;
• detecting return times of feedback information of a plurality of subsequent data packets after the first data packet;
• determining a cause of the timeout of the feedback information of the first data packet when detecting that the return times of the feedback information of the plurality of subsequent data packets after the first data packet meet a preset return time requirement;
• and
• increasing data sending rate of the terminal from a current third value to a fourth value when determining that the timeout is caused by a packet loss on the wireless link in the communications link, wherein the third value is greater than or equal to the second value and is less than the first value.

A non-transitory computer-readable medium storing computer instructions, which when run on a computer, enable the computer to perform a method, the method comprising:

• when determining that a return time of feedback information of a first data packet has timed out, reducing a data sending rate of a connection to which the first data packet belongs from a first value to a second value, wherein the first data packet is a data packet sent by the terminal to a target device over a communications link that comprises a wireless link and a wired link;
• detecting return times of feedback information of a plurality of subsequent data packets after the first data packet;
• determining a cause of the timeout of the feedback information of the first data packet when detecting that the return times of the feedback information of the plurality of subsequent data packets after the first data packet meet a preset return time requirement;
• and
• increasing a data sending rate of the terminal from a current third value to a fourth value when determining that the timeout is caused by a packet loss on the wireless link in the communications link, wherein the third value is greater than or equal to the second value and is less than the first value.
