Description

Technical Field

[0001] This application relates to the field of data processing technology, and in particular to data transmission control methods, apparatus, devices and storage media. Background Technology

[0002] Various protocols, such as Transmission Control Protocol (TCP) and serial port protocols, are used in streaming data transmission. However, network environments are often complex and affected by multiple factors, such as signal interference, network congestion, and hardware failures, making data transmission prone to errors. Currently, a common method for controlling data transmission is to set up a checkpoint based on the data volume. However, this checkpoint only performs verification upon completion of data reception, and the verification mechanism used is relatively simple. Obviously, verification upon completion of data reception can result in invalid transmissions, wasting a significant amount of time, and leading to the reading of incorrect data due to header information interference. Therefore, the accuracy and efficiency of the above method for controlling data transmission are relatively low.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main objective of this application is to provide a data transmission control method, apparatus, device, and storage medium, which aims to solve the technical problem of low accuracy and efficiency in controlling data transmission in the prior art.

[0005] To achieve the above objectives, this application proposes a data transmission control method, the method comprising:

[0006] When receiving network stream data sent by the sending end, target header information is read from the network stream data, wherein the target header information includes length information, magic number information, and information content;

[0007] The magic number information is hashed to obtain the current magic number hash value;

[0008] When the current magic number hash value is consistent with the preset hash value and the length information is within the preset range, calculate the cyclic redundancy check value of the information content;

[0009] When the cyclic redundancy check value is inconsistent with the preset value, the data transmission between the sender and the data retransmission terminal is controlled according to the data retransmission request.

[0010] In one embodiment, the step of performing a hash calculation on the magic number information to obtain the current magic number hash value includes:

[0011] Determine the target hash algorithm used by the sending end to perform hash calculations on key information;

[0012] Obtain the configuration parameters of the target hash algorithm;

[0013] Based on the target hash algorithm, the magic number information is hashed according to the configuration parameters to obtain the current magic number hash value.

[0014] In one embodiment, after the step of hashing the magic number information to obtain the current magic number hash value, the method further includes:

[0015] When the current magic number hash value is inconsistent with the preset hash value and / or the length information is not within the preset range, the network connection with the sending end is disconnected, and a current error message is generated;

[0016] The current error information is tagged with a type based on the first tag, and the tagged current error information is then stored in the database.

[0017] Re-establish the network connection with the sending end.

[0018] In one embodiment, the step of controlling data transmission with the sending end according to a data retransmission request when the cyclic redundancy check value is inconsistent with a preset value includes:

[0019] When the cyclic redundancy check value is inconsistent with the preset value, a data retransmission request is generated;

[0020] Send the data retransmission request to the sending end;

[0021] Receive the erroneous data packet sent by the sending end according to the data retransmission request, and control the data transmission between the sending end according to the erroneous data packet.

[0022] In one embodiment, after the step of controlling data transmission between the sender and the data retransmission request, the method further includes:

[0023] Obtain the identification information of the target header information;

[0024] The next header information is read from the network stream data according to the identification information, wherein the next header information includes the next length information, the next magic number information, and the next information content;

[0025] The next magic number information is hashed to obtain the next magic number hash value;

[0026] When the next magic number hash value is consistent with the preset hash value, the next length information is within the preset range, and the cyclic redundancy check value of the next information content is inconsistent with the preset value, the step of generating a data retransmission request is repeated.

[0027] In one embodiment, after repeatedly executing the step of generating a data retransmission request when the next magic number hash value is consistent with a preset hash value, the next length information is within a preset range, and the cyclic redundancy check value of the next information content is inconsistent with a preset value, the method further includes:

[0028] Count the current number of times when the magic number hash value is inconsistent with the preset hash value and the length information is not within the preset range;

[0029] When the current number of attempts exceeds a preset number, the network connection with the sending end is disconnected, and a target error message is generated;

[0030] The target error information is tagged with a type based on the second tag, and the tagged target error information is then stored in the database.

[0031] In one embodiment, after repeatedly executing the step of generating a data retransmission request when the next magic number hash value is consistent with a preset hash value, the next length information is within a preset range, and the cyclic redundancy check value of the next information content is inconsistent with a preset value, the method further includes:

[0032] Count the number of times the cyclic redundancy check value is inconsistent with the preset value;

[0033] If the target number of times exceeds the preset number of times, the step of disconnecting the network connection with the sending end continues.

[0034] Furthermore, to achieve the above objectives, this application also proposes a data transmission control device, which includes:

[0035] The reading module is used to read target header information from the network stream data when receiving network stream data sent by the sending end. The target header information includes length information, magic number information, and information content.

[0036] The calculation module is used to perform hash calculation on the magic number information to obtain the current magic number hash value;

[0037] The calculation module is also used to calculate the cyclic redundancy check value of the information content when the current magic number hash value is consistent with the preset hash value and the length information is within the preset range;

[0038] The control module is used to control the data transmission between the sender and the data retransmission terminal according to the data retransmission request when the cyclic redundancy check value is inconsistent with the preset value.

[0039] In addition, to achieve the above objectives, this application also proposes a data transmission control device, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the data transmission control method as described above.

[0040] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and which, when executed by a processor, implements the steps of the data transmission control method described above.

[0041] One or more technical solutions proposed in this application have at least the following technical effects: When receiving network stream data sent by a sending end, target header information is read from the network stream data, wherein the target header information includes length information, magic number information, and information content; the magic number information is hashed to obtain a current magic number hash value; when the current magic number hash value is consistent with a preset hash value and the length information is within a preset range, a cyclic redundancy check (CRC) value for the information content is calculated; when the CRC value is inconsistent with a preset value, data transmission between the sending end and the receiving end is controlled according to a data retransmission request. Through the above method, the multi-dimensional information included in the network stream data is parsed, and then the length information and magic number information in the target header information are strictly verified, achieving the goal of ensuring the accuracy of data transmission from the source. Furthermore, by verifying the information content through check value comparison, data corruption during transmission can be detected in a timely manner, and when verification fails, a request is made to the sending end to retransmit, thereby effectively improving the accuracy and efficiency of data transmission control and making it suitable for various complex network environments.

[0048] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or receiving end capable of performing the above functions. The following description uses a receiving end as an example to illustrate this embodiment and the subsequent embodiments.

[0050] Based on this, embodiments of this application provide a data transmission control method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the data transmission control method of this application.

[0051] In this embodiment, the data transmission control method includes steps S10 to S40:

[0052] Step S10: When receiving network stream data sent by the sending end, read the target header information from the network stream data, wherein the target header information includes length information, magic number information, and information content.

[0053] It should be noted that network stream data refers to network data transmitted in a streaming manner between the sending end and the receiving end, while target header information refers to fixed-length header information read from the network stream data. The target header information, including length information, magic number information, and information content, can be obtained through parsing. The length information can be represented as dataLength, the magic number information can be represented as magicNum, and the information content can be represented as data.

[0054] Step S20: Perform a hash calculation on the magic number information to obtain the current magic number hash value.

[0055] It is understandable that the current magic number hash value refers to the hash value of the magic number information. This current magic number hash value can be calculated by the target hash algorithm used by the sending end to perform hash calculation on the key information. This has uniqueness and randomness, can distinguish different data packets, and has high security and is not easy to be forged.

[0056] Further, after step S20, the method further comprises: when the current magic number hash value is inconsistent with the preset hash value and / or the length information is not within the preset range, disconnecting the network connection with the transmitting end, and generating current error information; performing type marking on the current error information based on a first tag, and storing the marked current error information into a database; re-establishing the network connection with the transmitting end.

[0057] It should be understood that when any of the conditions that the current magic number hash value is inconsistent with the preset hash value and the length information is not within the preset range is satisfied, it indicates that the verification of the target header information fails. At this time, the network connection with the transmitting end is immediately disconnected to avoid invalid transmission, save a large amount of time and network resources, and significantly reduce transmission delay and improve the overall transmission efficiency when the network is busy. The first tag refers to a tag that marks the error type as a target header information error. After the current error information is generated, the current error information is type-marked based on the first tag, and the marked current error information is recorded by means of database storage. At the same time, a reconnection process is started, that is, the network connection with the transmitting end is re-established.

[0058] Step S30: when the current magic number hash value is consistent with the preset hash value and the length information is within the preset range, calculate a cyclic redundancy check value of the information content.

[0059] It should be understood that the preset hash value refers to a hash value calculated by the transmitting end using the same target hash algorithm. After the current magic number hash value is obtained, it is necessary to determine whether the current magic number hash value is consistent with the preset hash value and whether the length information is within the preset range. If both are true, it indicates that the verification of the target header information is successful, and at this time, the cyclic redundancy check value of the information content is further calculated. For example, the preset range may be expressed as [minLength, maxLength]. If minLength < dataLength < maxLength, it indicates that the length information is within the preset range. If dataLength < minLength or dataLength > maxLength, it indicates that the length information is not within the preset range, that is, it is determined that the length information is erroneous.

[0060] Step S40: when the cyclic redundancy check value is inconsistent with a preset value, control data transmission with the transmitting end according to a data retransmission request.

[0061] It's understandable that the preset value refers to the cyclic redundancy check value used to verify the information content. This preset value can be represented as expectedCRC, and the cyclic redundancy check value of the information content can be represented as calculatedCRC. If calculatedCRC != expectedCRC, it indicates that the CRC check has failed. In this case, the receiving end will send a data retransmission request to the sending end and control the data transmission between them based on the retransmission request. Conversely, if calculatedCRC == expectedCRC, it indicates that the CRC check has succeeded, and data reception is complete. In other words, through the above CRC check, data corruption during transmission can be detected in a timely manner, and when the CRC check fails, the sending end is requested to retransmit the erroneous data packet, ensuring that the data received by the receiving end is consistent with the data sent by the sending end, thereby effectively improving the accuracy of transmitted data.

[0062] Further, step S40 includes: generating a data retransmission request when the cyclic redundancy check value is inconsistent with a preset value; sending the data retransmission request to the sending end; receiving the erroneous data packet sent by the sending end according to the data retransmission request, and controlling the data transmission between the sending end and the sending end according to the erroneous data packet.

[0063] It should be understood that a data retransmission request indicates a request for the sender to transmit only erroneous data packets. For the receiver, after generating a data retransmission request, it sends the data retransmission request to the sender. At this time, the sender will determine the erroneous data packets based on the data retransmission request and only retransmit the erroneous data packets to the receiver, rather than the entire data sequence, thereby avoiding the situation of duplicate data transmission.

[0064] Furthermore, after the step of controlling the data transmission between the sender and the data retransmission request, the method further includes: obtaining the identification information of the target header information; reading the next header information from the network stream data according to the identification information, wherein the next header information includes the next length information, the next magic number information, and the next information content; performing a hash calculation on the next magic number information to obtain the next magic number hash value; and repeatedly executing the step of generating a data retransmission request when the next magic number hash value is consistent with a preset hash value, the next length information is within a preset range, and the cyclic redundancy check value of the next information content is inconsistent with a preset value.

[0065] Understandably, to facilitate the reading of the next header information from network stream data, it is necessary to obtain the identification information of the target header information, i.e., to quickly locate the next header information and continue the transmission process, ensuring the continuity of data transmission and further improving data transmission efficiency. The next header information includes the next length information, the next magic number information, and the next information content. After calculating the next magic number hash value, the hash value, length information, and cyclic redundancy check (CRC) value are also judged. Specifically, it is judged whether the next magic number hash value is consistent with the preset hash value, whether the next length information is within the preset range, and whether the CRC value of the next information content is consistent with the preset value. If the next magic number hash value is consistent with the preset hash value, the next length information is within the preset range, and the CRC value of the next information content is inconsistent with the preset value, it indicates that the next header information verification is successful and the CRC check fails. In this case, the sender will still be requested to retransmit the erroneous data packet to avoid the situation of duplicate data transmission.

[0066] Furthermore, after repeatedly executing the step of generating a data retransmission request when the next magic number hash value is consistent with the preset hash value, the next length information is within the preset range, and the cyclic redundancy check value of the next information content is inconsistent with the preset value, the method further includes: counting the current number of times the magic number hash value is inconsistent with the preset hash value and the length information is not within the preset range; when the current number is greater than the preset number, disconnecting the network connection with the sending end and generating target error information; marking the target error information based on the second tag and storing the marked target error information in the database.

[0067] It should be understood that the current count refers to the number of times the magic number hash value is inconsistent with the preset hash value and the length information is not within the preset range. After multiple verifications using a multi-dimensional and rigorous verification mechanism, the current count of times the magic number hash value is inconsistent with the preset hash value and the length information is not within the preset range is counted. When the current count is greater than the preset count, it indicates that multiple header information verifications have failed, and the network connection with the sending end is disconnected. The second tag refers to the tag that marks the error type as multiple errors and disconnection. After generating the target error information, the target error information is tagged based on the first tag, and the tagged target error information is recorded in the database.

[0068] Furthermore, after repeatedly executing the step of generating a data retransmission request when the next magic number hash value is consistent with the preset hash value, the next length information is within the preset range, and the cyclic redundancy check value of the next information content is inconsistent with the preset value, the method further includes: counting the target number of times the cyclic redundancy check value is inconsistent with the preset value; and continuing to execute the step of disconnecting the network connection with the sending end when the target number is greater than the preset number.

[0069] It is understood that the target count refers to the number of times the cyclic redundancy check (CRC) value is inconsistent with the preset value. When the target count exceeds the preset count, it indicates that multiple CRC checks have failed. In this case, the network connection with the sending end will be disconnected, a target error message will be generated, and a type marking will be performed. The preset count can be 2 times, or it can be adaptively adjusted according to actual needs. Therefore, by utilizing the above error handling mechanism, whether the disconnection and reconnection are caused by multiple header information verification failures or multiple CRC check failures, it can ensure that unstable connections are promptly severed and reliable connections are re-established when serious errors occur, thus guaranteeing the stability of data transmission. Moreover, this embodiment can effectively handle transmission errors and ensure the reliability of data transmission even in various complex network environments.

[0070] This embodiment reads target header information from the network stream data sent by the receiving end. The target header information includes length information, magic number information, and information content. A hash calculation is performed on the magic number information to obtain a current magic number hash value. When the current magic number hash value matches a preset hash value and the length information is within a preset range, a cyclic redundancy check (CRC) value for the information content is calculated. When the CRC value does not match a preset value, data transmission between the receiving end and the sending end is controlled according to a data retransmission request. By parsing the multi-dimensional information included in the network stream data and then rigorously verifying the length and magic number information in the target header information, the accuracy of data transmission is guaranteed from the source. Furthermore, by verifying the information content through checksum comparison, data corruption during transmission can be detected promptly. If verification fails, a retransmission request is made to the sending end, thereby effectively improving the accuracy and efficiency of data transmission control and making it suitable for various complex network environments.

[0071] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 Step S20 includes steps S201 to S203:

[0072] Step S201: Determine the target hash algorithm used by the sending end to perform hash calculation on the key information.

[0073] It should be noted that the target hash algorithm refers to the hash algorithm used by the sending end to perform hash calculations on the key information. In order to effectively improve the accuracy of verifying the target header information, the hash algorithm used to calculate the magic number information in this embodiment is the same as the hash algorithm used by the sending end to perform hash calculations on the key information, i.e., the target hash algorithm, which can be the MD5 hash algorithm. The key information of the sending end includes, but is not limited to, the packet number, timestamp, source IP address, and destination IP address.

[0074] Step S202: Obtain the configuration parameters of the target hash algorithm.

[0075] It is understandable that configuration parameters refer to the parameters configured when using the target hash algorithm, including but not limited to function type, iteration parameters, etc.

[0076] Step S203: Based on the target hash algorithm, perform hash calculation on the magic number information according to the configuration parameters to obtain the current magic number hash value.

[0077] It should be understood that the current magic number hash value refers to the hash value of the magic number information. After obtaining the magic number information, the magic number information is hashed according to the target hash algorithm and the configuration parameters to obtain the current magic number hash value.

[0078] This embodiment determines the target hash algorithm used by the sending end to perform hash calculations on key information; obtains the configuration parameters of the target hash algorithm; and performs hash calculations on the magic number information based on the target hash algorithm and the configuration parameters to obtain the current magic number hash value. By determining the target hash algorithm used by the sending end to perform hash calculations on key information, obtaining the configuration parameters of the target hash algorithm, and configuring it accordingly, hash calculations on the magic number information based on the target hash algorithm can effectively improve the accuracy of calculating the current magic number hash value, thereby improving the accuracy of verifying the target header information.

[0079] This application also provides a data transmission control device, please refer to... Figure 3 The data transmission control device includes:

[0080] The reading module 10 is used to read target header information from the network stream data when receiving network stream data sent by the sending end. The target header information includes length information, magic number information, and information content.

[0082] The calculation module 20 is further configured to calculate the cyclic redundancy check value of the information content when the current magic number hash value is consistent with the preset hash value and the length information is within the preset range.

[0083] The control module 30 is used to control the data transmission with the sending end according to the data retransmission request when the cyclic redundancy check value is inconsistent with the preset value.

[0084] This embodiment reads target header information from the network stream data sent by the receiving end. The target header information includes length information, magic number information, and information content. A hash calculation is performed on the magic number information to obtain a current magic number hash value. When the current magic number hash value matches a preset hash value and the length information is within a preset range, a cyclic redundancy check (CRC) value for the information content is calculated. When the CRC value does not match a preset value, data transmission between the receiving end and the sending end is controlled according to a data retransmission request. By parsing the multi-dimensional information included in the network stream data and then rigorously verifying the length and magic number information in the target header information, the accuracy of data transmission is guaranteed from the source. Furthermore, by verifying the information content through checksum comparison, data corruption during transmission can be detected promptly. If verification fails, a retransmission request is made to the sending end, thereby effectively improving the accuracy and efficiency of data transmission control and making it suitable for various complex network environments.
