Description

Data transmission method and device and computing equipment Technical Field The present invention relates to the field of computer technologies, and in particular, to a data transmission method, apparatus, and computing device. Background With the continuous development of computer technology, it has become one of the main ways to transmit data between devices. A common data transmission method includes that a transmitting end creates a transmission link between the transmitting end and a receiving end based on a transmission control protocol (transmission control protocol, TCP) or a user datagram protocol (user datagram protocol, UDP), and then the transmitting end transmits target data to be transmitted to the receiving end through the transmission link, so that the receiving end receives the target data. The transmission link is configured with a nominal rate to ensure that the target data can be sent to the receiving end within a preset duration. However, in a high concurrency scenario, when the actual rate of the target data transmitted by the transmission link cannot reach the rated rate of the link, the target data cannot be sent to the receiving end within a preset duration, and the sending efficiency of the target data is reduced. Disclosure of Invention The application provides a data transmission method, a data transmission device and a computing device, which can improve the sending efficiency of target data. In order to achieve the above purpose, the embodiment of the application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a data transmission method, where target data is transmitted between a transmitting device and a receiving device based on multiple links, where a sum of rated rates of the multiple links is an expected rate, where the expected rate is a rate at which transmission of the target data is completed within a preset duration, and the method includes acquiring an actual rate of each of the multiple links in a process of transmitting the target data based on the multiple links, increasing a rated rate of a first link of the multiple links when the sum of the actual rates of the multiple links is less than the expected rate, decreasing a rated rate of a second link of the multiple links, where the actual rate of the first link is equal to the rated rate of the first link, and the actual rate of the second link is less than the rated rate of the second link, where the sum of the rated rates of the multiple links after adjustment is the expected rate. The embodiment of the application provides a data transmission method, because the sum of the rated rates of the links after adjustment is the expected rate, the total transmission resources of the links are not changed, but the blocked second link reduces the occupation of the transmission resources by reducing the rated rate of the second link with smaller transmission rate, and the reduction of the rated rate of the second link is increased to the rated rate of the first link with higher transmission rate, so that the first link with higher transmission rate transmits more data at higher rate, thereby ensuring that the target data is transmitted within the preset duration, and the transmission efficiency of the target data is improved. In one possible implementation manner, the increasing the rated rate of the first link in the plurality of links includes increasing the rated rate of the first link by a first value, where the first value corresponding to any one of the first links is greater than or equal to 0, and the sum of the first values corresponding to all the first links is equal to the value of a first differential rate, where the first differential rate is a difference between the expected rate and the sum of the actual rates of the plurality of links. In the above embodiment, since the actual rates of all the first links reach their rated rates, the first differential rates are equally distributed as the increment to all the first links, that is, the first value corresponding to any one of the first links is the average value of the first differential rates equally distributed to all the first links, thereby improving the fairness guarantee of the first links. In one possible implementation, the first value corresponding to any one of the first links is an average value that assigns the first differential rate to all of the first links. In one possible implementation manner, the reducing the rated rate of the second links in the plurality of links includes reducing the rated rate of the second links by a second value, wherein the second value corresponding to any one of the second links is greater than or equal to 1, the second value corresponding to one of the second links is inversely proportional to the difference between the actual rate of the one second link and the rated rate, and the sum of the second values corresponding to all of the second links is equ
