Existing congestion control algorithms mainly determine the following behavior by the state of the state machine when the sender receives an acknowledgment character. However, the conventional congestion control algorithm has an advantage in a relatively stable network condition, and as the wireless technology is explosively increased, a stable network state of wireless communication does not exist. Signal attenuation is still an inevitable problem in wireless communication, and thus network delay is caused, so that the data transmission rate of the whole network is reduced.

For the convenience of understanding the embodiment, a detailed description will be first given of a data transmission method disclosed in the embodiment of the present invention.
Example 1
Fig. 1 is a schematic flow chart of a data transmission method according to an embodiment of the present invention. The method is applied to a client, and the client is in communication connection with a server through a UDP protocol.
As seen in fig. 1, the method comprises the steps of:
step S101: if packet loss is detected in the data transmission process, adjusting the timeout time of the automatic retransmission request based on the UDP protocol; the timeout time is used for indicating the time length of data delay sending caused by data packet loss in the data transmission process.
In this embodiment, if a packet loss is detected during data transmission, an ARQ protocol is invoked in the computer memory to adjust the automatic repeat request timeout by the ARQ protocol based on the UDP protocol. The ARQ protocol adjusts the time-out time of the automatic retransmission by adjusting the coefficient of the recovery time target.
Step S102: based on the adjusted timeout time, a window size of the sliding window is determined.
In actual operation, data transmission is performed based on the adjusted timeout time, then unacknowledged packets in the UDP packets are calculated, so as to obtain the data throughput rate at that time, and finally the window size of the sliding window is adjusted based on the data throughput rate.
Step S103: and adjusting the transmission rate of the data according to the window size of the sliding window so as to transmit the data according to the adjusted transmission rate.
The invention controls the frequency of sending data by two factors of the size of the sending cache and the size of the residual receiving cache of the receiving end, and adopts a non-yielding flow control strategy to sacrifice bisection and bandwidth utilization rate to improve the fluency of data transmission.
The data transmission method, the data transmission device and the electronic equipment are applied to a client, wherein the client is in communication connection with a server through a UDP protocol; the method comprises the following steps: if packet loss is detected in the data transmission process, adjusting the timeout time of the automatic retransmission request based on the UDP protocol; the timeout time is used for indicating the time length of data delay sending caused by data packet loss in the data transmission process; determining a window size of the sliding window based on the adjusted timeout time; and adjusting the transmission rate of the data according to the window size of the sliding window so as to transmit the data according to the adjusted transmission rate. The method determines the window size of the sliding window again by adjusting the timeout time of the automatic retransmission, thereby adjusting the data transmission speed and improving the transmission speed of the existing network data.

The method is applied to a client, and the client is in communication connection with a server through a UDP protocol.

step S201: if packet loss is detected in the data transmission process, adjusting the timeout time of the automatic retransmission request based on the UDP protocol; the timeout time is used for indicating the time length of data delay sending caused by data packet loss in the data transmission process.
In this embodiment, the step of adjusting the timeout period of the data transmission based on the UDP protocol includes: first, the coefficients of a preset recovery time target for data transmission are adjusted based on the UDP protocol. Then, the timeout time for data transmission is adjusted according to the coefficient of the recovery time target.
In one embodiment, the recovery time target has a factor of 1.5.
Step S202: determining an unacknowledged data packet in a data packet header of the UDP protocol based on the adjusted timeout; the unacknowledged data packet is used to indicate that data prior to the currently transmitted data packet has been received by the server.
In this embodiment, the step of determining the unacknowledged packet in the UDP header based on the adjusted timeout period includes: firstly, receiving a confirmation character response message returned by the server based on the adjusted overtime. Then, according to the acknowledgement character response message, the unacknowledged data packet in the data packet header of the UDP protocol is determined.
Step S203: and determining the window size of the sliding window according to the unacknowledged data packet.
In actual operation, the step of determining the window size of the sliding window according to the unacknowledged packet comprises: first, the real-time throughput rate of the currently transmitted data is determined based on the unacknowledged data packets. The window size of the sliding window is then determined based on the real-time throughput rate.
In one possible implementation, the step of determining the window size of the sliding window according to the real-time throughput rate includes: firstly, according to the real-time throughput rate, determining a smooth throughput rate in a preset time. Then, a window size of the sliding window is determined based on the smoothed throughput rate.
Step S204: and adjusting the transmission rate of the data according to the window size of the sliding window so as to transmit the data according to the adjusted transmission rate.
In this embodiment, the method further comprises the following steps A1-A2:
step A1: and determining the lost data packet according to the confirmation character response message.
Step A2: the missing data packet is retransmitted.
In this embodiment, if the received remote acknowledgement character is ACK during data transmission: p1, P3, P4, P5. When the first acknowledgement character is ACK ═ P3, the protocol layer knows that P2 is skipped 1 time, and when ACK ═ P4 is received, the protocol layer knows that P2 is skipped 2 times, at this time, it can think that P2 is lost, and does not wait for timeout, and directly retransmit P2 packet, so as to implement fast retransmission.
The data transmission method, the data transmission device and the electronic equipment are applied to a client, wherein the client is in communication connection with a server through a UDP protocol; the method comprises the following steps: if packet loss is detected in the data transmission process, adjusting the timeout time of the automatic retransmission request based on the UDP protocol; the timeout time is used for indicating the time length of data delay sending caused by data packet loss in the data transmission process; determining an unacknowledged data packet in a data packet header of the UDP protocol based on the adjusted timeout; the unacknowledged data packet is used for indicating that data before the current transmission data packet is received by the server; determining the window size of a sliding window according to the unacknowledged data packet; and adjusting the transmission rate of the data according to the window size of the sliding window so as to transmit the data according to the adjusted transmission rate.
