[0022] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0023] Please refer to Figure 1 , Figure 1 The flowchart of the multi-transmission path collaborative control method provided for the first embodiment. Although the logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown in the drawings. Specifically, the multi-transmission path collaborative control method provided in this first embodiment is applied to a sending end, which refers to a device or system that initiates data transmission. The sending end may be a server, a router, a gateway, or a terminal device such as a smart phone or a tablet.

[0024] The specific process of this multi-transmission path collaborative control method is as follows: S101, obtain multiple performance indicators of each preset transmission path in different dimensions in real time.

[0025] Among them, the preset transmission path refers to a pre-configured heterogeneous communication link. Exemplarily, the preset transmission path here may at least include five types: XingShan, Wi-Fi, 5G, Bluetooth, and wired path. Different communication links each have unique characteristics. Among them, XingShan is good at low-power short-distance communication, Wi-Fi is suitable for high-speed data transmission, 5G has a larger coverage range and lower latency, Bluetooth is mainly used for short-distance device connection, and although wired networks are stable, they have poor flexibility. The purpose of the present invention is to effectively manage the collaboration of these paths when performing multi-path transmission.

[0026] Among them, the performance indicator here refers to a quantitative indicator for measuring communication quality. Exemplarily, it may include end-to-end transmission delay, effective throughput, bit error rate, and power consumption per unit bit, etc., and can be specifically defined according to actual needs.

[0027] Optionally, extend the Netlink subsystem of Linux to establish efficient communication between user-space processes and the kernel network stack using Netlink Sockets, and achieve real-time monitoring of multiple preset transmission paths. The specific methods include: listening to Traffic Control (TC) to obtain bandwidth information, calculating latency using TCP timestamp, obtaining packet loss rate through network status statistics tools, and combining power consumption monitoring tools to monitor the power consumption per bit. The user-space process listens for network status changes based on non-blocking Netlink Sockets, updates the path quality evaluation data in real time, and provides a basis for optimizing the transmission strategy, thereby improving the stability and efficiency of data transmission.

[0028] S102, calculate the path quality of each preset transmission path based on multiple performance metrics.

[0029] Among them, the path quality is the result of a comprehensive evaluation of each preset transmission path, indicating the degree to which the path is suitable for data transmission under the current conditions.

[0030] Optionally, calculate the path quality in the kernel space. The path quality can be the result of a weighted calculation based on multiple performance metrics. A higher path quality means that the path is suitable for efficient transmission.

[0031] S103, determine the current transmission strategy, and allocate and transmit the sharded data packets based on the transmission strategy and the path quality of each preset transmission path.

[0032] Among them, the transmission strategy determines how to use each link in the network. It can be understood that according to the quality of the current link and the transmission requirements, the transmission strategy can have different forms. For example, single-path transmission: select an optimal path in real time for data transmission. Multi-path transmission: divide the data into multiple shards and allocate them to different paths for parallel transmission. Path priority: set priorities for different paths and determine the preferred choice for data transmission according to the path quality. Load balancing: dynamically adjust the allocation ratio of data traffic according to the quality of each path to achieve load balancing between paths.

[0033] Optionally, in the Linux network stack, during the process of allocating transmission paths for sharded data packets, the packet distribution is scheduled through a Queueing Discipline (qdisc) to achieve data traffic control between different paths.

[0034] The above multi-transmission path collaborative control method first monitors multiple performance indicators of each preset transmission path in real time, then calculates the path quality based on these indicators, and finally the sender dynamically determines the transmission path of the data packet according to the current transmission strategy and the path quality. The core advantage of this method is that it can effectively solve the problem that different links in the existing communication system cannot work collaboratively. By intelligently selecting the path through the transmission strategy and the path quality, heterogeneous links can efficiently cooperate in the same network, improving the stability, efficiency, and reliability of the overall data transmission.

[0035] Optionally, in a specific embodiment, the multiple performance indicators include the acquisition bandwidth, delay, and packet loss rate. The specific steps for calculating the path quality of each preset transmission path based on the multiple performance indicators in S102 are as follows: A1. Obtain the extreme value of the acquisition bandwidth and the extreme value of the delay.

[0036] Among them, the extreme value of the acquisition bandwidth is the maximum value or the minimum value of the acquisition bandwidths of the multiple preset transmission paths, and the extreme value of the delay is the maximum value or the minimum value .

[0037] A2. For each preset transmission path, calculate the first ratio between the corresponding acquisition bandwidth and the extreme value of the acquisition bandwidth, and calculate the second ratio between the corresponding delay and the extreme value of the delay. Calculate the path quality by weighting the first ratio, the second ratio, and the packet loss rate.

[0038] Among them, the first ratio is used to measure the relative advantage of the path bandwidth. The larger the bandwidth, the higher the ratio. The second ratio is used to measure the relative disadvantage of the delay. The smaller the delay, the lower the ratio and the higher the score. The packet loss rate refers to the proportion of lost data packets in the total data packets during transmission, reflecting the reliability of the path. The lower the packet loss rate, the better the quality of the path.

[0039] Optionally, both the extreme value of the acquisition bandwidth and the extreme value of the delay are the maximum values. The corresponding path quality calculation formula can be:

[0040] Among them, is the path quality of the j-th path, is the weight coefficient, configured by the user-mode control interface. is the acquisition bandwidth of the j-th path, is the delay of the j-th path, is the packet loss rate of the j-th path. Of course, in the above formula, both the extreme value of the acquisition bandwidth and the extreme value of the delay can also be the minimum values.

[0041] In this specific embodiment, through the dynamic evaluation and management of multiple heterogeneous paths, the system can give full play to the advantages of different paths, avoid the burden on a single link, reduce the risk of network congestion or disconnection, and ensure the stability and reliability of data transmission.

[0042] Optionally, in a specific embodiment, determining the current transmission strategy in S103, and allocating and transmitting the sharded data packets based on the transmission strategy and the path quality of each preset transmission path specifically includes the following sub-steps: B1. If the current transmission strategy is a single-path transmission strategy, then use the preset transmission path with the highest current path quality as the target path, and allocate all sharded data packets to the target path for transmission.

[0043] Among them, the single-path transmission strategy means that in the transmission process, one path is selected from multiple paths for data transmission, and multiple paths are not used for parallel transmission. Under this strategy, the path with the best quality is selected as the target path, and the target path will receive all sharded data packets for transmission.

[0044] B2. Use all preset transmission paths other than the target path as alternative paths. Whenever the path quality of the target path is less than the preset quality threshold, use the alternative path with the highest current path quality as the target path.

[0045] That is to say, in the transmission process, the sending end monitors the quality of the target path in real time. Once the quality of the target path drops, it will check whether it is lower than the set quality threshold. If the quality of the target path is lower than the threshold, the sending end will reselect an alternative path with the best quality as the new target path for data transmission.

[0046] In this specific embodiment, by dynamically selecting paths and real-time monitoring path quality, the system can effectively avoid data loss or transmission interruption caused by poor quality of a certain path, and improve the overall transmission stability.

[0047] Optionally, in a specific embodiment, determining the current transmission strategy in S103, and allocating and transmitting the sharded data packets based on the transmission strategy and the path quality of each preset transmission path specifically includes the following sub-steps: C1. If the current transmission strategy is a multi-path transmission strategy, calculate the corresponding allocation ratio based on the path quality of each preset transmission path.

[0048] Among them, the multi-path transmission strategy means that in the data transmission process, multiple paths are used to transmit data in parallel, and the allocation ratio refers to that under the multi-path transmission strategy, the system determines the load ratio allocated to each path based on the quality of each path. In this specific embodiment, the higher the path quality, the larger the allocated ratio. Optionally, the calculation formula for the allocation ratio is:

[0049] Among them, represents the allocation ratio of path j, is the path quality of the j-th path.

[0050] C2, allocate and transmit the sharded data packets based on the allocation ratio.

[0051] That is, the system allocates the sharded data packets according to the ratio of different paths. The amount of data transmitted on each path is proportional to its ratio, so as to achieve load balancing.

[0052] This specific embodiment can dynamically adjust the allocation ratio according to the real-time quality change of each path, ensure that the optimal path is always selected for data transmission, and thus enhance the adaptability of the system to network fluctuations.

[0053] Figure 2 It is a schematic flowchart of the multi-transmission path collaborative control method provided by the second embodiment. Specifically, the multi-transmission path collaborative control method provided by this second embodiment is applied to the receiving end, and the receiving end refers to a device or module responsible for receiving, processing, and reorganizing data, which can specifically be a smart phone, a tablet computer, and various Internet of Things devices, such as smart home sensors, industrial sensors, etc.

[0054] The specific process of this multi-transmission path collaborative control method is as follows: S201, receive multiple sharded data packets.

[0055] Among them, the multiple sharded data packets are sent through the multi-transmission path collaborative control method applied to the sending end.

[0056] S202, sort and reorganize the multiple sharded data packets to obtain a reorganized data packet.

[0057] At the receiving end, the multiple sharded data packets are sent by the sending end through the multi-path transmission control method. The task of the receiving end is to receive these sharded data packets and ensure that it can identify that they are different parts of the same data packet. Once the receiving end receives the sharded data packets, it needs to sort them according to information such as the sequence number and timestamp of each shard. This process ensures that the received shards can be arranged in the correct order and avoids out-of-order situations. After sorting, the receiving end will recombine these shards to form a complete data packet to ensure the correctness and integrity of the data.

[0058] Optionally, in a specific embodiment, after receiving the multiple sharded data packets, the following steps are further executed: D1, obtain the clock offset of the calibration path sent by the sending end, and perform clock calibration based on the clock offset.

[0059] Among them, the calibration path refers to the path with the minimum time delay among multiple preset transmission paths. This path has the lowest time delay fluctuation among multiple paths. Therefore, it can provide the most accurate clock synchronization information to ensure the clock synchronization of all paths in the system. The clock offset refers to the time difference between the clocks at the receiving end and the sending end, which is expressed as:

[0060] Among them, and are timestamps measured through the calibration path, is the time at the sending end, is the time when the receiving end receives the data packet. and are also timestamps measured through the calibration path, is the local time of the receiving end, is the time when the receiving end receives the data packet at another time point.

[0061] If the clock offset result is not zero, the receiving end can adjust its clock to be synchronized. For example, if the clock of the receiving end is 5 ms ahead of the clock of the sending end, the receiving end will subtract 5 ms to correct the local clock, so as to synchronize to the clock of the sending end.

[0062] In this way, through calibration based on the clock offset, the receiving end can keep the clock synchronized with the sending end, eliminate the receiving time error caused by clock inconsistency, and ensure that the data packets are received in the correct order.

[0063] Optionally, in a specific embodiment, the performance metric includes time delay. Sorting and reorganizing the multiple fragmented data packets in S202 to obtain the reorganized data specifically includes the following sub-steps: E1. Update the reception time of the target fragmented data packet according to the time delay of the target transmission path to obtain the target reception time.

[0064] Among them, the target transmission path is any one of the multiple preset transmission paths, and the target fragmented data packet is any fragmented data packet sent under the target transmission path. That is to say, this step performs the same update operation on all fragmented data packets under the same transmission path. Optionally, the formula for this time delay update is:

[0065] Among them, is the reception time of the target fragmented data packet i, is the time delay of the target transmission path j, is the target reception time of the target fragmented data packet i.

[0066] E2, sort according to the target reception time of each fragmented data packet, and reorganize all the fragmented data packets according to the sorting result to obtain a reorganized data packet.

[0067] That is to say, according to the target reception time of each fragment, the receiving end sorts multiple fragments. The fragment with an earlier target reception time is sorted first to ensure that the data packet is reorganized in chronological order. After the sorting is completed, the receiving end reorganizes all the fragmented data packets into a complete original data packet according to the sorting result.

[0068] Through delay correction in this specific embodiment, the receiving end can ensure that all fragments are correctly reorganized in order, thereby reducing incorrect transmissions caused by delay differences or path instability and improving the reliability of data transmission.

[0069] To facilitate better implementation of the multi-transmission path cooperative control method of this application, this application also provides a multi-transmission path cooperative control device based on the above multi-transmission path cooperative control method, which is applied to the sending end. The meanings of the nouns are the same as those in the above multi-transmission path cooperative control method, and the specific implementation details can refer to the description in the method embodiment.

[0070] Please refer to Figure 3 , Figure 3 is a schematic structural diagram of the multi-transmission path cooperative control device provided by the embodiment of this application, which may specifically include: An index acquisition module 301, configured to acquire multiple performance indexes of each preset transmission path in different dimensions in real time; A path quality calculation module 302, configured to calculate the path quality of each preset transmission path based on multiple performance indexes; A transmission module 303, configured to determine the current transmission strategy, and allocate the transmission path of the fragmented data packet based on the transmission strategy and the path quality of each preset transmission path and perform transmission.

[0071] For the above multi-transmission path cooperative control device, the index acquisition module 301 is used to first monitor multiple performance indexes of each preset transmission path in real time, the path quality calculation module 302 is used to calculate the path quality according to these indexes, and the transmission module 303 is used for the sending end to dynamically determine the transmission path of the data packet according to the current transmission strategy and the path quality. The core advantage of this device is that it can effectively solve the problem that different links in the existing communication system cannot work together, and intelligently select paths through the transmission strategy and path quality, enabling heterogeneous links to cooperate efficiently in the same network, and improving the overall stability, efficiency and reliability of data transmission.

[0072] In one embodiment, the multiple performance metrics include acquisition bandwidth, latency, and packet loss rate. Calculating the path quality of each preset transmission path based on the multiple performance metrics includes: obtaining the extreme value of the acquisition bandwidth and the extreme value of the latency; wherein, the extreme value of the acquisition bandwidth is the maximum or minimum value of the acquisition bandwidth of multiple preset transmission paths, and the extreme value of the latency is the maximum or minimum value of the latency of multiple preset transmission paths; for each preset transmission path, calculating a first ratio between the corresponding acquisition bandwidth and the extreme value of the acquisition bandwidth, and calculating a second ratio between the corresponding latency and the extreme value of the latency, and calculating the path quality by weighted calculation based on the first ratio, the second ratio, and the packet loss rate.

[0073] In one embodiment, determining the current transmission strategy, allocating and transmitting the sharded data packets based on the transmission strategy and the path quality of each preset transmission path includes: if the current transmission strategy is a single-path transmission strategy, taking the preset transmission path with the highest current path quality as the target path, and allocating all sharded data packets to the target path for transmission. Taking all preset transmission paths other than the target path as alternative paths, and whenever the path quality of the target path is less than a preset quality threshold, taking the alternative path with the highest current path quality as the target path.

[0074] In one embodiment, determining the current transmission strategy, allocating and transmitting the sharded data packets based on the transmission strategy and the path quality of each preset transmission path includes: if the current transmission strategy is a multi-path transmission strategy, calculating a corresponding allocation ratio based on the path quality of each preset transmission path; wherein, there is a positive correlation between the allocation ratio of each preset transmission path and the corresponding path quality; allocating and transmitting the sharded data packets based on the allocation ratio.

[0075] To facilitate better implementation of the multi-transmission path collaborative control method of the present application, the present application also provides a multi-transmission path collaborative control device based on the above multi-transmission path collaborative control method, which is applied to the receiving end. The meanings of the terms are the same as those in the above multi-transmission path collaborative control method, and the specific implementation details can refer to the description in the method embodiments.

[0076] Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of the multi-transmission path collaborative control device provided by the embodiments of the present application, and specifically may include: A data receiving module 401, configured to receive multiple sharded data packets; wherein, the multiple sharded data packets are sent by using the multi-transmission path collaborative control method applied to the sending end; A sorting and recombination module 402, configured to sort and recombine the multiple sharded data packets to obtain a recombined data packet.

[0077] For the above multi - transmission path collaborative control device, the data receiving module 401 is used to receive these fragmented data packets and ensure that it can identify that they are different parts of the same data packet. The sorting and recombination module 402 is used to sort the fragmented data packets according to information such as the sequence number and timestamp of each fragment once they are received. This process ensures that the received fragments can be arranged in the correct order, avoiding out - of - order situations. After sorting, these fragments are recombined to form a complete data packet, ensuring the correctness and integrity of the data.
