Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the method of adjusting the TCP sending window through packet loss and interaction between the sending module and the application processor in the prior art when the TCP message stored at the sending end is about to exceed the carrying capacity of the transmission resource The defect that the throughput rate of the sending end will drop significantly and cannot be recovered quickly provides a relatively simple way to send the sending end without increasing the number of interfaces and the number of interactions between the application processor and the data sending module at the sending end. A data transmission method, system, electronic device, and storage medium in which the average throughput rate and the average throughput rate received by the receiving end are maintained at a relatively high level

Embodiment 1

[0057] This embodiment provides a data transmission method, the data transmission method is applied to the sending end, such as figure 1 As shown, the data transfer method includes:

[0058] Step 101, monitor the storage space currently occupied by the TCP packets to be sent stored by the data sending module.

[0059] It should be understood that during the process of monitoring the storage space, the data receiving module may also continuously receive TCP packets sent to it by the peer end. In other words, the TCP messages currently stored by the data receiving module include not only previously stored TCP messages but also newly received TCP messages.

[0060] It should be understood that step 101 in this embodiment monitors the storage space in real time, for example, it may be monitored at intervals.

[0061] Step 102, judging whether the storage space is greater than or equal to the first storage threshold: if yes, execute step 103; if not, execute step 112.

Embodiment 2

[0087] This embodiment provides a data transmission system, the data transmission system is applied to the sending end, such as figure 2 As shown, the data transmission system includes: a data monitoring module 201 , a storage space judgment module 202 , an information type detection module 203 and a priority submission module 204 .

[0088] The data monitoring module 201 is used for monitoring the storage space occupied by the TCP packets currently stored by the data sending module to be sent. It should be understood that during the process of monitoring the storage space, the data receiving module may also continuously receive TCP packets sent to it by the peer end. In other words, the TCP messages currently stored by the data receiving module include both previously stored TCP messages and newly received TCP messages.

[0089] It should be understood that, in this embodiment, the data monitoring module 201 monitors the storage space in real time, for example, the data mon...

Embodiment 3

[0105] An embodiment of the present invention also provides an electronic device, which can be expressed in the form of a computing device (for example, it can be a server device), including a memory, a processor, and a computer program stored in the memory and operable on the processor, wherein The data transmission method in Embodiment 1 of the present invention can be implemented when the processor executes the computer program.

[0106] image 3 A schematic diagram of the hardware structure of this embodiment is shown, as image 3 As shown, the electronic device 9 specifically includes:

[0107] At least one processor 91, at least one memory 92, and a bus 93 for connecting different system components, including the processor 91 and the memory 92, wherein:

[0108] The bus 93 includes a data bus, an address bus, and a control bus.

[0109] The memory 92 includes a volatile memory, such as a random access memory (RAM) 921 and / or a cache memory 922 , and may further includ...

Abstract

The invention discloses a data transmission method, system, electronic equipment and storage medium. The data transmission method is applied to the sending end, and the data transmission method includes: monitoring the storage space occupied by the TCP message to be sent by the data sending module; judging whether the storage space is greater than or equal to the first storage threshold: if so, notifying the data receiving module to stop submitting includes TCP packet of TCP ACK information to application processor. In the present invention, first judge whether the storage space occupied by the TCP message is greater than or equal to the preset storage upper limit, if so, notify to stop sending TCP ACK information, and the application processor automatically adjusts the size of the TCP sending window, so that the application processor can be automatically adjusted without increasing the application processor. Under the interaction interface and the number of interactions with the data sending module, the throughput rate of the sending end can be maintained at a relatively stable level. In the long run, the average throughput rate of the sending end and the average throughput rate of the receiving end can be maintained at a high level.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, system, electronic equipment and storage medium. Background technique [0002] With the surge in the use of mobile communication devices, there is growing interest in mobile Internet and Web-based (network) applications. TCP (Transmission Control Protocol) is a popular transport layer protocol on the Internet, responsible for providing highly reliable data transmission over wired and wireless links. Any data packet loss will cause network congestion and reduce the data transmission rate of the sender. At the same time, when there is a large amount of data interaction, as the receiving end responds to the TCP message sent by the sending end, the sending end TCP will increase the size of the sending window and challenge the limit of transmission resources. Among them, the sending window can It is understood as the amount of data sent at one time. [...
