Description
Technical Field
The embodiment of the invention relates to the field of communication, in particular to a data transmission method, a data transmission device, a storage medium and an electronic device.
Background
With the development of technology and in order to adapt to heterogeneous network environments, many user terminals are often configured with multiple interfaces (e.g., Wi-Fi and 4G, 5G). In order to improve transmission performance, improve bandwidth utilization and enhance fault tolerance of a network by using characteristics of a plurality of network interfaces of a terminal, a plurality of multipath transmission protocols are provided. There are TCP-based and UDP-based. These protocols are aggregated over multiple sublinks. However, the inconsistency of the uplink bandwidth and the downlink bandwidth of the network is not considered, and the ratio of the uplink bandwidth to the downlink bandwidth of the network is about 1: 10, if the uplink bandwidth is insufficient, the data recovery fails, but the downlink bandwidth is still sufficient, the data is transferred to other links, and the network bandwidth is wasted.
A typical multipath transmission method is described below by taking a multipath protocol (e.g., mptcp protocol) as an example for communication between a terminal and a server:
the terminal and the server communicate in MPTCP (MPTCP protocol) topology, as shown in fig. 1, and the server and the terminal communicate using a multi-path transmission protocol (e.g., MPTCP protocol) and transmit using two paths, i.e., 4G and Wi-Fi. The schematic diagram of MPTCP transmission between the server and the terminal can be seen in fig. 2, and the data acknowledgement ACK on each path is transmitted only on the original path. The explanation is made according to the upper and lower bandwidths provided by the network operator: the downlink bandwidth of the Wi-Fi is 100Mbps, and the uplink bandwidth is 10 Mbps; the downlink bandwidth of 4G is 100Mbps, and the uplink bandwidth is 50 Mbps. Because the data acknowledgement ACK on each path is only transmitted on the original path, if packet loss, jitter and congestion occur in the uplink bandwidth of the Wi-Fi, the service end can reduce the transmission rate on the Wi-Fi and transfer part of the data to the 4G network for transmission; however, the downstream bandwidth of Wi-Fi is sufficient, which results in a reduced bandwidth utilization on the Wi-Fi link and, on the other hand, increases the consumption of 4G network traffic.
Therefore, the related art has the problem that the data transmission wastes bandwidth.
In view of the above problems in the related art, no effective solution has been proposed.

In this embodiment, after the target sub-path is determined, the first data may be sent through the target sub-path. Before sending data, the target sub-path may first determine whether the target sub-path currently has a capability of sending the first data, in the case that the target sub-path determines that the target sub-path has the capability of sending the first data, the data packet may be read from the sending buffer, in the case that the data packet is read, the protocol header is added to the data packet, and the data packet with the protocol header added thereto is sent through the target sub-path.

Step S812, the data receiving module is exited.
In the foregoing embodiment, the data transmission structure diagram can refer to fig. 9, and as shown in fig. 9, the structure includes a multipath data transmission scheduling module, a data sending module, a data receiving module, and a congestion control module. The data transmission method is positioned below the application layer and above the UDP transmission layer, UDP can be used as a bottom layer transmission carrier to be suitable for real-time transmission of audio and video, and the whole direction is positioned in a user mode to be more convenient to update and deploy. The multi-path data transmission scheduling module is responsible for scheduling data issued by the application layer to a plurality of transmission paths, detecting a plurality of interfaces and establishing multi-path transmission. The data sending module is responsible for the sending control process of the data. The data receiving module is responsible for the receiving process and the reply processing process of the data.

The data packet is sent to the terminal through the downlink of the path 2, the reply packet in a common multi-path transmission protocol (for example, an mptcp protocol) is only sent back to the server end on the uplink of the path 2, and if the uplink bandwidth of the path 2 is insufficient, the packet is lost, and congestion occurs, the downlink speed of the path 2 is reduced, so that the bandwidth utilization rate of the system is reduced. In the above embodiment, when the reply packet is transmitted, 2 optimal paths may be selected to transmit the reply packet, and the reply packet may be returned to the server end through the uplink of path 1 in the schematic system, so that the downlink bandwidth of path 1 may not be slowed down even if the uplink reply packet through path 2 is lost, thereby improving the bandwidth utilization of the system and solving the problem of bandwidth waste caused by inconsistent uplink and downlink bandwidths.
