When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] The soft bus multipath transmission control method based on the super object model described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the soft bus multipath transmission control method based on the super object model includes the following steps:

[0052] Step S10: construct a super object model, where the super object model is a data model based on a super device distributed system.

[0053] Specifically, the super object model is a core data model based on the super device distributed system. The super object model is used to describe the computing power, storage capacity, network bandwidth, path information and spatial attribute description information of each node. The super object model contains the hardware description information, software middleware description information, path information and spatial attribute description information of each physical node. Through the super object model, the resources of the entire distributed system can be fully described and managed, providing a basis for resource scheduling and data transmission.

[0054] The hardware description information is used to provide basic data for resource scheduling and data transmission, and includes: the CPU type and core number of the node, memory capacity, storage space, network interface type and total bandwidth.

[0055] It is understandable that the hyper-object model first needs to include the hardware description information of each physical node. This information includes the node's CPU type and core number, memory capacity, storage space, network interface type and bandwidth, etc. Through detailed hardware description, we can fully understand the hardware resource status of each node and provide basic data for resource scheduling and data transmission.

[0056] The software middleware description information is used to help the system match task requirements, and the software middleware description information includes: software services, algorithm models, and data processing capabilities running on each node. In addition to hardware resources, the super object model also needs to include information about software middleware. This information includes software services, algorithm models, data processing capabilities, etc. running on each node. The software middleware description can help the system more accurately match task requirements and node capabilities when performing task scheduling.

[0057] The path information is used to describe the network status between each node, including the bandwidth, delay, packet loss rate and reliability of each path. Path information is a very important part of the super object model, which is used to describe the network connection between each node. It includes indicators such as bandwidth, delay, packet loss rate, reliability, etc. of each path, which are the basis for multipath transmission path selection.

[0058] The spatial attribute description information is used to optimize data transmission path selection and resource scheduling, and the spatial attribute description information includes the geographical location, spatial coordinate system and coverage area of ​​the device. The super object model needs to record the spatial location information of each device and data. The spatial attribute description includes the geographical location, spatial coordinate system, coverage area, etc. of the device. This information can be used to optimize data transmission path selection and resource scheduling, especially in distributed systems with wide geographical distribution.

[0059] Furthermore, the construction of the super object model collects data from each physical node in the distributed system through automated scripts and management tools to obtain node data, and the node data includes the hardware description information, the software middleware description information, the path information and the space attribute description information.

[0060] In this embodiment, firstly, it is necessary to conduct comprehensive data collection on each node in the distributed system. The content of data collection includes the hardware resources, software services, network connection status and spatial location information of the node. Data collection can be performed through automated scripts and management tools to ensure the real-time and accuracy of the data.

[0061] Furthermore, the collected node data is stored in a centralized database, and the centralized database is managed using distributed database technology.

[0062] In this embodiment, the collected node information needs to be stored in a centralized database to facilitate subsequent query and analysis. Distributed database technology, such as Hadoop HDFS, Apache Cassandra, etc., can be used to support the storage and management of large-scale data.

[0063] Furthermore, a super object model is constructed according to the data in the centralized database, and a comparison and verification is performed with the super object model based on a known multipath transmission technology to obtain a verification result of the super object model.

[0064] In this embodiment, the data structure of the super object model is designed based on the collected data. The data structure should be extensible and flexible to facilitate the maintenance of adding new nodes or updating node information in the future. Standard data formats such as JSON, XML, etc. can be used for data description. At the same time, after the super object model is built, verification is required to ensure the accuracy and completeness of the model. By comparing the actual node information with the data in the super object model, possible errors and omissions can be found and corrected.

[0065] It is understandable that the super object model also needs regular maintenance to ensure the real-time and accuracy of the data. An automatic update mechanism can be set up to automatically update the corresponding data in the super object model when the node information changes.

[0066] Step S20: Obtain the network status in the super object model, and obtain multiple target transmission paths through a path selection algorithm according to the network status.

[0067] Multipath transmission path selection is based on the path information in the super-object model. By selecting multiple transmission paths, efficient and reliable data transmission is achieved. Multipath transmission can make full use of network resources and avoid the bottleneck problem of single-path transmission.

[0068] Specifically, the network status between nodes is obtained from the path information of the super object model through a network monitoring tool; based on the network status, multiple target transmission paths are obtained through a heuristic algorithm or a dynamic programming algorithm, and a target transmission path set is generated based on the multiple target transmission paths.

[0069] It is understandable that obtaining multiple target transmission paths first requires comprehensive information collection of each path in the distributed system. Path information can be collected in real time through network monitoring tools, and the content of path information collection includes indicators such as bandwidth, delay, packet loss rate, and reliability. Design a path selection algorithm based on the collected path information. The path selection algorithm needs to comprehensively consider factors such as the bandwidth, delay, packet loss rate, and reliability of the path, and select the optimal transmission path (obtained by weighting bandwidth maximization, delay minimization, packet loss rate minimization, and reliability maximization). Heuristic algorithms, dynamic programming algorithms, etc. can be used for path selection.

[0070] The multipath transmission path selection of the present application has the following advantages: Efficient transmission: Through multipath transmission path selection, network resources can be fully utilized to improve data transmission efficiency. Multiple transmission paths can be used at the same time to avoid the bottleneck problem of single-path transmission. High reliability: Multipath transmission path selection can improve the reliability of data transmission. When a path fails, it can quickly switch to other paths to ensure reliable data transmission. Dynamic scheduling: Multipath transmission path selection has dynamic scheduling capabilities and can dynamically adjust the transmission path according to changes in path status. Ensure the real-time and efficient data transmission.

[0071] Step S30: split the original data packet to be transmitted into multiple sub-data packets, and allocate different target transmission paths to the multiple sub-data packets through a path allocation algorithm.

[0072] Data fragmentation and scheduling are key steps to achieve multipath transmission. By splitting a large data packet into multiple small data packets and allocating them to different transmission paths according to the path selection algorithm, the efficiency and reliability of data transmission can be improved.

[0073] Specifically, the fragmentation size is determined according to the size of the original data and the bandwidth of the target transmission path, and the original data is fragmented according to the fragmentation size to obtain multiple sub-data packets; data scheduling is performed on the multiple sub-data packets through a load balancing algorithm or a heuristic algorithm, and different target transmission paths are allocated to the multiple sub-data packets.

[0074] It is understandable that the large data packet needs to be fragmented first, and split into multiple small data packets. In this embodiment, the data fragmentation algorithm is responsible for splitting the large data packet into multiple small data packets. The data fragmentation needs to ensure the independence and integrity of each small data packet to facilitate subsequent transmission and reorganization; the data fragmentation algorithm can use fixed-size fragmentation or dynamic fragmentation, and determine the size of the fragmentation according to the size of the data packet and the bandwidth of the transmission path.

[0075] Furthermore, after the data fragmentation is completed, data scheduling is performed on the plurality of sub-data packets. The data scheduling algorithm dynamically adjusts the allocation of data packets according to the path selection algorithm. Load balancing algorithms, heuristic algorithms, etc. can be used for data scheduling to ensure the balance of data packet allocation and transmission efficiency.

[0076] Step S40: synchronously coordinate the plurality of sub-data packets to obtain a plurality of coordinated sub-data packets, input the plurality of coordinated sub-data packets into the corresponding target transmission path for transmission, and output an ordered data stream.

[0077] Transmission coordination is a key step to ensure the integrity and reliability of data transmission. By synchronously coordinating data packets transmitted over multiple paths, the fault tolerance and reliability of data transmission can be effectively improved.

[0078] Specifically, timestamps and sequence numbers are added to the plurality of sub-data packets to complete synchronization coordination, thereby obtaining a plurality of coordinated sub-data packets; based on a multi-path transmission protocol, the plurality of coordinated sub-data packets are input into the corresponding target transmission path for transmission, and an ordered data stream is output.

[0079] It can be understood that the synchronization and coordination of data packets ensures that the data packets transmitted by multiple paths arrive at the receiving end in order; the data packets are synchronized and coordinated through timestamps and sequence numbers. In this embodiment, by adding timestamps and sequence numbers to the data packets, it is ensured that the data packets arrive at the receiving end in order, so as to achieve synchronization and coordination of the data packets transmitted by multiple paths. And based on the multipath transmission protocol (such as MPTCP), it is responsible for managing the synchronization and coordination of data packets to ensure the integrity of the data.

[0080] Step S50: Collect error information and packet loss information in the ordered data stream, correct the error and packet loss information through erasure coding technology and error recovery mechanism, and output the corrected complete data stream.

[0081] Error recovery is also a key step in ensuring the integrity and reliability of data transmission. Using erasure coding technology for error recovery can effectively improve the fault tolerance and reliability of data transmission.

[0082] Specifically, before data packets are transmitted, erasure coding technology is used to generate redundant data. Erasure coding technology can use Reed-Solomon codes, LDPC codes, etc., to improve the fault tolerance of data transmission by adding redundant information to the original data. When data packets are lost or erroneous, they are recovered through redundant data. The receiving end uses erasure coding technology to recover lost or erroneous data packets to ensure the reliability of data transmission.

[0083] The reliability of data transmission can be effectively improved through packet synchronization coordination and erasure coding technology. During multi-path transmission, data packets are ensured to arrive in order and are recovered when data packets are lost or erroneous to ensure data integrity. Erasure coding technology provides high fault tolerance for data transmission. When data packets are lost or erroneous, they are recovered through redundant data to avoid data transmission failure. Finally, through transmission coordination and error recovery, the system has dynamic adjustment capabilities. It can dynamically adjust the transmission and recovery strategies of data packets according to the path status and data transmission conditions to ensure the efficiency and reliability of data transmission.

[0084] Step S60: receiving the complete data stream, reorganizing the complete data stream in sequence to obtain restored original data, and verifying and optimizing the original data.

[0085] Data reception and reassembly is the last step of multipath transmission. It receives data packets transmitted by multiple paths and reassembles them in sequence to restore the original data. Data reception and reassembly ensure the integrity and accuracy of data transmission. The reassembled data is verified and optimized to ensure the accuracy and reliability of the data.

[0086] Specifically, the complete data stream is received through a multipath transmission protocol, and the complete data stream is sorted and reorganized according to the timestamps and sequence numbers corresponding to the coordinated sub-data packets in the complete data stream to obtain restored original data.

[0087] In this embodiment, it is first necessary to receive data packets on multiple paths through a multipath transmission protocol (such as MPTCP). The multipath transmission protocol is responsible for managing the reception and synchronization of data packets to ensure the complete transmission of data. The received data packets need to be sorted and reassembled according to the timestamp and sequence number. The data packet reassembly algorithm sorts the data packets according to the timestamp and sequence number of the data packets, and combines them into the original data to ensure the accurate transmission of the data. It also has fault-tolerant recovery capabilities. When data packets are lost or erroneous, they can also be recovered through the above-mentioned erasure code technology, that is, the receiving end uses the erasure code technology to recover lost or erroneous data packets to ensure the integrity of data transmission.

[0088] Furthermore, the original data is verified by means of a verification technology, path transmission performance feedback information is obtained according to the verification result, the data transmission process is optimized according to the path transmission performance feedback information using an optimization strategy to obtain target data, and a performance report is generated according to the path transmission performance feedback information; wherein the optimization strategy includes adjusting the transmission path or using a data scheduling strategy.

[0089] It can be understood that verification is to check and verify the transmission results to ensure the accuracy and integrity of the data, and optimization is to optimize the data transmission process based on the transmission performance feedback. The transmission efficiency and reliability can be improved by adjusting the transmission path, data scheduling strategy, etc.

[0090] In this embodiment, the transmission result needs to be verified first to ensure the accuracy and integrity of the data. The transmission result can be verified by verification and technology, such as CRC verification, MD5 hash, etc.; then, the data transmission process is optimized according to the transmission performance feedback. The transmission efficiency and reliability can be improved by adjusting the transmission path, data scheduling strategy, etc. The result optimization needs to comprehensively consider the transmission performance indicators, such as bandwidth, delay, packet loss rate, etc., and perform all-round optimization. Finally, a performance report is generated based on the transmission performance feedback information of the path. Performance feedback provides an optimization basis for subsequent data transmission. Through continuous monitoring and analysis of the transmission process, problems in the transmission process can be discovered and solved, and the transmission efficiency and reliability can be continuously improved.

[0091] Furthermore, if Figure 2 As shown, based on the above-mentioned soft bus multipath transmission control method based on the super object model, the present invention also provides a soft bus multipath transmission control system based on the super object model, wherein the soft bus multipath transmission control system based on the super object model includes:

Figure 3 Only some components of the terminal are shown, but it should be understood that it is not required to implement all of the components shown, and more or fewer components may be implemented instead.

In one embodiment, a soft bus multipath transmission control program 40 based on a super object model is stored on the memory 20, and the soft bus multipath transmission control program 40 based on the super object model can be executed by the processor 10, thereby realizing the soft bus multipath transmission control method based on the super object model in the present application.
