Description

Technical Field

[0001] The present invention relates to the field of communications, and more specifically, to a method and apparatus for transmitting data. Background Technology

[0002] When dealing with large data transmission tasks, TCP, as a reliable transport protocol, can efficiently achieve complete data transmission under stable network conditions. However, in weak network environments, due to the higher packet loss rate, TCP's congestion control and cumulative acknowledgment mechanisms lead to a decrease in throughput, resulting in a significant performance degradation of TCP in such environments. While UDP offers faster transmission rates than TCP in weak network conditions, it is unreliable and prone to data loss, duplication, and out-of-order delivery.

[0003] TCP and UDP transmissions each have their advantages and disadvantages depending on the network transmission scenario. In time-varying network environments where round-trip time (RTT) and packet loss rate change over time, using a single transmission protocol will have corresponding drawbacks, leading to data transmission errors.

[0025] The methods and embodiments provided in this application can be executed on a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 This is a hardware structure block diagram of a mobile terminal for a data transmission method according to an embodiment of the present invention. Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0026] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the data transmission method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the aforementioned method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0027] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0028] This embodiment provides a method for transmitting data on the aforementioned mobile terminal. Figure 2 This is a flowchart of a data transmission method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0029] Step S202: Obtain the current number of threads of the first transmission protocol and the transmission rate of the first transmission protocol to obtain the first number of threads and the first transmission rate;

[0030] The first transmission protocol mentioned above is the TCP transmission protocol, which can establish a TCP connection between the client and the server as a control connection.

[0031] The TCP_RATE variable can be defined to store the average transmission rate (including the first transmission rate mentioned above) of the last data block transmitted using TCP, with an initial value of 0. The TCP_N variable can be defined to store the number of threads currently using TCP for transmission (including the first transmission rate mentioned above), with an initial value of 0.

[0032] Step S204: Obtain the current number of threads of the second transmission protocol and the transmission rate of the second transmission protocol to obtain the second number of threads and the second transmission rate;

[0033] The second transport protocol is UDP. UDP_RATE is defined to store the average transmission rate of the last data block transmitted using UDP, with an initial value of 0. UDP_N is defined to store the number of threads currently using UDP for transmission, with an initial value of 0.

[0034] Step S206: Determine the transmission protocol of the target data block based on the first number of threads and the first transmission rate, as well as the second number of threads and the second transmission rate.

[0035] Specifically, such as Figure 3 The flowchart shown includes the following steps:

[0036] Step S301: Determine whether the number of the first threads is zero; if the number of the first threads is zero, proceed to step S302; if the number of the first threads is non-zero, proceed to step S303.

[0037] Step S302: Determine that the first transmission protocol transmits the target data block;

[0038] Step S303: Determine whether the second thread count is zero. If the second thread count is zero, proceed to step S304; otherwise, proceed to step S305.

[0039] Step S304: Determine that the second transmission protocol transmits the target data block.

[0040] Step S305: If both the first number of threads and the second number of threads are non-zero, determine whether the first transmission rate and the second transmission rate are equal; if the first transmission rate and the second transmission rate are equal, proceed to step S306; if the first transmission rate and the second transmission rate are not equal, proceed to step S307.

[0041] Step S306: Determine whether the first number of threads is less than or equal to the second number of threads. If yes, determine that the first transmission protocol transmits the target data block; otherwise, determine that the second transmission protocol transmits the target data block.

[0042] Step S307: Determine the transmission protocol with a higher transmission rate to transmit the target data block.

[0043] In the above embodiments, the transmission advantages of TCP and UDP in different network environments are leveraged, and multi-threaded block transmission is used to achieve efficient data transmission under unstable network transmission links.

[0044] Step S208: If it is determined that the target data block is transmitted through the second transmission protocol, the target data block is encoded by the target encoding method, and the encoded target data block is transmitted through the second transmission protocol, wherein the reliability of the first transmission protocol is higher than that of the second transmission protocol.

[0045] Step S210: If it is determined that the target data block is to be transmitted via the first transmission protocol, the target data block is transmitted via the first transmission protocol.

[0046] The target encoding method mentioned above can be fountain code.

[0047] Optionally, the entity performing the above steps may be a background processor or other devices with similar processing capabilities, or a machine that integrates at least an image acquisition device and a data processing device. The image acquisition device may include an image acquisition module such as a camera, and the data processing device may include a terminal such as a computer or a mobile phone, but is not limited thereto.

[0048] Through the above steps, the transmission protocol for the target data block is determined based on the current number of threads and transmission rate of the first and second transmission protocols, achieving the goal of adaptively selecting the transmission protocol for data transmission. Furthermore, when the target data block is determined to be transmitted via the second transmission protocol, it is encoded using a target encoding method to avoid data loss, duplication, and out-of-order issues caused by the lower reliability of the second transmission protocol. Therefore, the problem of data transmission errors caused by using a single transmission protocol can be solved, thereby improving the accuracy of data transmission.

[0049] The execution order of steps S202 and S204 can be interchanged; that is, step S204 can be executed first, and then step S202 can be executed.

[0050] As an optional implementation, such as Figure 3 The flowchart shown also includes the following steps:

[0051] Step S309: If it is determined that the target data block is transmitted through the first transmission protocol, increment the current thread count of the first transmission protocol by one.

[0052] Step S310: After transmitting the target data block through the first transmission protocol, decrement the current thread count of the first transmission protocol by one, and obtain the transmission rate of the target data block transmitted by the first transmission protocol to obtain the third transmission rate.

[0053] Step S311: Update the transmission rate of the first transmission protocol to the third transmission rate.

[0054] Step S312: If it is determined that the target data block is transmitted through the second transmission protocol, increment the current thread count of the second transmission protocol by one.

[0055] Step S313: After transmitting the encoded target data block through the second transmission protocol, decrement the current thread count of the second transmission protocol by one, and obtain the transmission rate of the target data block transmitted by the second transmission protocol to obtain the fourth transmission rate.

[0056] Step S314: Update the transmission rate of the second transmission protocol to the fourth transmission rate.

[0057] As an optional implementation, such as Figure 4 The flowchart shown includes the following steps before transmitting the target data block:

[0058] Step S401: Establish a TCP connection between the client and the server as a control connection. The fountain code uses the LT code and is based on the UDP transport layer protocol. The client application layer defines a value of 2N as the maximum value of the total number of TCP and UDP threads. The value of N can be set according to the actual situation, such as 10, 20, etc.

[0059] Step S402: Define TCP_RATE to store the average transmission rate of the last data block transmitted using TCP, with an initial value of 0. Define TCP_N to store the number of threads currently using TCP for transmission, with an initial value of 0; define UDP_RATE to store the average transmission rate of the last data block transmitted using UDP, with an initial value of 0. Define UDP_N to store the number of threads currently using UDP for transmission, with an initial value of 0.

[0060] Step S403: The client application layer defines a callback function pointer, which is used by this algorithm to notify the application layer of the transmission result of each data block;

[0061] In step S404, if the transmission task has not ended, the client application layer continues to put the block universal unique identifier (uuid) and block data into the cache; if TCP_N+UDP_N<2N, then the data block is retrieved from the cache and transmitted accordingly.

[0062] In step S404, the client algorithm notifies the server of the block UUID through the control channel and selects a transmission mode between TCP and UDP for transmission. The transmission mode selection follows these principles:

[0063] If the number of TCP connections is 0, then TCP_N is incremented by 1, and TCP transmission is selected;

[0064] If the number of UDP connections is 0, then UDP_N is incremented by 1, and fountain code transmission is selected;

[0065] If TCP_RATE == UDP_RATE, choose the transmission method with fewer transmission threads;

[0066] If TCP_RATE ≠ UDP_RATE, choose the transmission method with the higher transmission rate.

[0067] Until the data blocks are completely transmitted or an error occurs, the result is notified to the application layer through a callback function, and the thread count for the corresponding transmission method is decremented by one;

[0068] If a data block is used correctly for TCP transmission, calculate the average transmission rate of the data block after the thread has finished transmitting it, and write it into TCP_RATE; if a data block is used correctly for UDP transmission, calculate the average transmission rate of the data block after the thread has finished transmitting it, and write it into UDP_RATE.

[0069] Maintain a keepalive signal every 5 seconds on the control connection. If no keepalive response is received after 3 attempts, all connections are considered invalid. At this point, all connections are cleaned up and an error is reported to the application layer.

[0070] In the above embodiments, fountain codes generate random data packets at the sender through encoding and decoding algorithms. The receiver can recover the original data by collecting enough linearly independent data packets from the data stream. In network conditions such as weak networks, interference, and multipath transmission, fountain codes are an effective method to achieve reliable data transmission. This application proposes a TCP and UDP adaptive transmission method for time-varying network large transmission tasks, and proposes an algorithm to automatically adjust the TCP and UDP transmission modes according to the network transmission conditions to achieve more efficient data transmission.
