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
As technology advances and in order to accommodate 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 by utilizing the characteristics of a plurality of network interfaces of a terminal, improve bandwidth utilization, and enhance fault tolerance of a network, a plurality of multipath transmission protocols are proposed. There are TCP-based and UDP-based. These protocols are all aggregated over multiple sub-links. But the non-uniform uplink and downlink bandwidths of the network are not considered, and the current uplink and downlink bandwidth ratio of the network is about 1: insufficient upstream bandwidth results in failure of data recovery, but insufficient downstream bandwidth results in data transfer to other links, wasting network bandwidth.
The following describes a typical multipath transmission method by taking a multipath protocol (e.g., mptcp protocol) for communication between a terminal and a server as an example:
the topology diagram of the communication between the terminal and the server in MPTCP can be seen in fig. 1, where the server and the terminal use a multipath transmission protocol (such as MPTCP protocol) to perform communication, and use two paths, namely 4G and Wi-Fi to perform transmission. The schematic diagram of MPTCP transmission performed by 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 description is based on the bandwidth provided by the network operator: the downlink bandwidth of Wi-Fi is 100Mbps, and the uplink bandwidth is 10Mbps; the downstream bandwidth of 4G is 100Mbps, and the upstream bandwidth is 50Mbps. Because the data acknowledgement ACK on each path is transmitted only on the original path, if packet loss, jitter and congestion occur in the uplink bandwidth of Wi-Fi, the server side can reduce the transmission rate on Wi-Fi and transfer part of data to the 4G network for transmission; however, the downlink bandwidth of Wi-Fi is sufficient, which results in a decrease in bandwidth utilization in Wi-Fi link, and on the other hand, increases the consumption of 4G network traffic.
As can be seen from the above, the related art has a problem that the data transmission wastes bandwidth.
In view of the above problems in the related art, no effective solution has been proposed at present.

In the above-described embodiment, in the case where it is determined that the terminal and the server establish a plurality of paths for transmitting data, the monitoring information of each sub-path included in the plurality of paths is determined. The monitoring information may include bandwidth, packet loss rate, channel quality, congestion condition, etc. of each sub-path. After the monitoring information is determined, a target sub-path may be determined according to the monitoring information, for example, an optimal path may be selected to transmit data.
In the above embodiment, the execution subject of the above steps may be a terminal or a server, and when the execution subject is a terminal, the data transmission is uplink transmission, and when the execution subject is a server, the data transmission is downlink transmission. When the data is uplink transmission, after the data issued by the application layer is acquired, the data can be distributed to one or more paths with good path quality included in the multiple transmission paths to transmit the data.
According to the invention, under the condition that a plurality of paths for transmitting data are established between the terminal and the server, monitoring information of each sub-path included in the paths is determined, a target sub-path for transmitting the first data is determined from the paths according to the monitoring information, and the first data is transmitted by using the target sub-path. The target sub-path for transmitting the first data can be determined according to the monitoring information of each sub-path, so that the condition that the paths to be transmitted are switched to other paths under the condition that the bandwidths of the sub-paths are sufficient is avoided, the problem that the bandwidths are wasted in data transmission in the related technology can be solved, and the utilization rate of the bandwidths under multiple paths is improved.
In an exemplary embodiment, before determining the monitoring information of each sub-path included in the plurality of paths, the method further comprises: detecting a first number of first transmission interfaces of the terminal for transmitting data and a first interface type of the first transmission interfaces, and detecting a second number of second transmission interfaces of the server for transmitting data and a second interface type of the second transmission interfaces; and establishing a plurality of paths when the first number and the second number are both greater than a predetermined threshold, and the first interface type indicates that the terminal is allowed to establish a plurality of transmission paths with the server and the second interface type indicates that the server is allowed to establish a plurality of path transmission paths with the terminal. In this embodiment, before determining the monitoring information of each sub-path included in the plurality of paths, the transmission interfaces and interface types of the terminal and the server may be detected to determine whether the terminal and the server allow the establishment of the plurality of paths. The number and the type of the interfaces of the equipment can be detected first, and guidance is provided for subsequent establishment of multipath transmission. Firstly, judging whether the upper layer allows the establishment of multi-path transmission, and if not, entering a single-path transmission flow. If so, checking whether the current client (terminal) and server (server) are allowed to establish a plurality of paths, and determining the number of transmission interfaces of the terminal and the server, wherein when the number of the transmission interfaces is larger than a preset threshold value and the terminal and the server are allowed to establish a plurality of paths, the plurality of paths are established between the terminal and the server. If the terminal and the server do not allow the establishment of multiple paths, a path transmission flow is entered but passed.
In one exemplary embodiment, determining the monitoring information for each sub-path included in the plurality of paths includes: acquiring a first reply packet transmitted by each sub-path, wherein the first reply packet is a data packet generated by response of opposite terminal equipment to received data, and the opposite terminal equipment comprises the terminal or the server; determining a network state of each of the sub-paths based on the first reply packet; the network state is determined as the monitoring information for each of the sub-paths. In this embodiment, the network state of each sub-path may be determined according to the received first reply packet, for example, RTT, packet loss rate, etc. of each sub-path may be calculated according to the first reply packet. And then the data of the network state information and the size of the congestion window are updated proportionally according to the calculation result.
In the above embodiment, referring to fig. 5, a flowchart of determining the monitoring information of each sub-path may be shown in fig. 5, where the determining the monitoring information of each sub-path may be determined by a congestion control module, and the flowchart includes:

In one exemplary embodiment, determining a target sub-path for transmitting first data from a plurality of the paths based on the monitoring information includes: determining a path selection rule based on the monitoring information; the target sub-path to send the first data is determined based on the path selection rule. In this embodiment, after a plurality of paths are established, a path selection rule may be determined first, and a target sub-path may be determined according to the path selection rule and monitoring information. The path selection rule may include a rule determined based on the priority of the sub-path, for example, a priority of the wired path may be set higher than a priority of the wireless path, a priority of the wireless path is higher than a priority of the 5G path, and a priority of the 5G path is higher than a priority of the 4G path. When the monitoring information indicates that the network state of each sub-path is at the same level, the target sub-path is determined according to the priority. When the monitoring information indicates that the network state of each sub-path is at different levels, the path with the optimal network state is determined as the target sub-path. When the monitoring information indicates that the network state of each sub-path is poor, the path with the top 2 of the network state rank is determined as a target sub-path. In the case where the target sub-path includes a plurality of sub-paths, data to be transmitted may be allocated according to network states of the plurality of sub-paths.

And then distributes the data to other sub-paths for transmission.
Step S614, whether to exit the multi-path transmission is determined according to the closing identifier of the multi-path transmission, if the closing identifier exists, step S616 is executed, and if the closing identifier does not exist, step S612 is executed.

In this embodiment, after determining the target sub-path, the first data may be sent through the target sub-path. Before transmitting data, the target sub-path may first determine whether the target sub-path currently has the capability of transmitting the first data, and if the target sub-path is determined to have the capability of transmitting the first data, the target sub-path may read the data packet from the transmission buffer, and if the data packet is read, add the protocol header to the data packet, and transmit the data packet to which the protocol header is added through the target sub-path.

In this embodiment, when the second data is received, the second reply packet may be determined according to the state of the second data, and a reply sub-path for sending the second reply packet is determined according to the monitoring information of each sub-path, and the second reply packet is transmitted through the reply sub-path. The state of the second data may include packet loss, packet non-loss, and the like. The reply sub-path may include one sub-path or may include a plurality of sub-paths, for example, 2, 3, etc.
In one exemplary embodiment, determining the second reply packet based on the status of the second data includes: determining that NACK information is included in the second reply packet under the condition that the state of the second data indicates that the data packet loss exists; and determining that the second reply packet comprises ACK information under the condition that the state of the second data indicates that no data packet loss exists. In this embodiment, when there is a packet loss in the received second data, the second reply packet with NACK information is recovered through the reply sub-path. And under the condition that the received second data has no packet loss, the second reply packet with the ACK information is recovered through a reply sub-path.

Step S812, the data receiving module is exited.
In the foregoing embodiment, the data transmission structure may be referred to as fig. 9, and as shown in fig. 9, the structure includes a multi-path data transmission scheduling module, a data transmitting 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, and UDP can be adopted as a bottom transmission carrier to be suitable for real-time transmission of audio and video, and the whole azimuth is positioned in a user mode so as to be more convenient to update and deploy. The multi-path data transmission scheduling module is responsible for scheduling the data issued by the application layer to a plurality of transmission paths, detecting multiple interfaces and establishing multi-path transmission. The data transmission module is responsible for the transmission control process of the data. The data receiving module is responsible for the receiving process and the replying process of the data. The congestion control module is responsible for detecting the network state of the path and controlling the congestion of the path.

The data packet goes down to the terminal through the path 2, and the reply packet only returns to the service end at the uplink of the path 2 in a common multipath transmission protocol (such as an mptcp protocol), if the uplink bandwidth of the path 2 is insufficient, packet loss and congestion occur, the downlink of the path 2 is caused to slow down, so that the bandwidth utilization rate of the system is reduced. In the above embodiment, when transmitting the reply packet, 2 optimal paths may be selected to transmit the reply packet, and in the illustrated system, the reply packet may be returned to the server through the uplink of the path 1, and even if the uplink reply packet through the path 2 is lost, the downlink bandwidth of the path 1 will not be reduced, so as to improve the bandwidth utilization rate of the system, and solve the problem of bandwidth waste caused by inconsistent uplink and downlink bandwidths.
