Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a data transmission method, device, equipment and storage medium. Background Art

[0002] One-way network communication is a branch of network communication. It can only realize one-way data transmission from the sender to the receiver. It often causes errors such as packet loss and bit change due to network congestion, weak signal, rain attenuation, etc., and directly affects the receiver to restore the correct data. In order to avoid the impact of such errors on data transmission, it is necessary to process the original data at the sender and the receiver according to predetermined rules to ensure that the receiver can check and correct the received data, and finally restore the correct and available data. Traditional solutions are mostly implemented with the help of network hardware such as repeaters, and data verification and error correction are mainly for a single data packet. Losing a data packet means losing a piece of data, which affects the integrity of the overall data. The missing data packet needs to be supplemented by retransmission. In one-way communication, the receiver and the sender do not communicate information. In order to ensure the integrity of the data, the sender generally chooses to resend all data packets multiple times to ensure that the receiver can receive complete data, which seriously affects the transmission efficiency. Therefore, how to reduce the impact of a single data packet loss on the overall data integrity in the process of one-way network communication is an urgent problem to be solved. Summary of the invention

[0020] Optionally, the determining, by the receiving end, target transmission data according to each of the reorganized data, and performing corresponding verification on the target transmission data to complete data transmission includes:

[0021] The receiving end determines redundant transmission data according to each of the reorganized data and the target redundant data, performs grouping error correction and de-redundancy operations on the redundant transmission data according to the target meta information, merges the corresponding error-corrected and de-redundancy data to obtain the target transmission data, and performs corresponding verification on the target transmission data to complete data transmission.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] At present, during one-way communication, data verification and error correction are mainly aimed at a single data packet. Losing a data packet means losing a section of data, which affects the integrity of the overall data. The missing data packet needs to be supplemented by retransmission. In one-way communication, there is no information communication between the receiver and the sender. In order to ensure data integrity, the sender generally chooses to retransmit all data packets multiple times to ensure that the receiving end can receive complete data, which seriously affects the transmission efficiency. In order to solve the above technical problems, the present application discloses a data transmission method, device, equipment and storage medium, which are applied to the sending end and can reduce the impact of the loss of a single data packet on the overall data integrity during one-way network communication.

[0044] See also Figure 1 As shown, an embodiment of the present invention discloses a data transmission method, which is applied to a sending end and includes:

[0045] Step S11, constructing data to be transmitted based on source data and verification data, grouping the data to be transmitted to obtain grouped data, and performing redundant encoding on each grouped data according to target redundant data to obtain encoded data groups.

[0046] In this embodiment, the transmitting end first constructs the data to be transmitted based on the source data and the verification data. It can be understood that the data to be transmitted = source data + verification data. In order to ensure the data security during the transmission process, the data to be transmitted obtained here is encrypted data, that is, the source data is the data obtained by encrypting the plaintext data through the encryption algorithm, and the verification data is the data obtained by converting the source data into a fixed-length data string using the digest algorithm. Then the data to be transmitted is grouped to obtain each packet data. When the data to be transmitted is grouped, the data packet length can be determined based on the data to be transmitted, the network maximum transmission unit and a pre-set redundancy ratio, and then the data to be transmitted is grouped based on the data packet length to obtain each packet data. That is, the data to be transmitted is combined with the network maximum transmission unit (MTU length, Maximum Transmission Unit), the redundancy ratio and other factors to calculate the length of each data packet, and the data to be transmitted is grouped to obtain each packet data. After obtaining each packet data, each packet data is redundantly encoded based on the target redundant data, so as to achieve the redundant data being attached to the corresponding packet data to obtain each encoded data group. Figure 2 As shown, in a specific implementation, the original data (i.e., source data) and verification data are first divided into t groups according to the data group length, each group having i data, to obtain t groups of grouped data, and the t groups of grouped data are redundantly encoded according to the target redundant data to obtain t groups of encoded data groups.

[0047] Step S12, rearrange each of the encoded data groups according to a preset cross-arrangement method to obtain corresponding target data packets, and combine each of the target data packets, the header information of the transmission protocol corresponding to the target data packets, and the target meta information to obtain each combined data; the target meta information is information representing the positioning information and verification information of the target data packet.

[0048] In this embodiment, the encoded data groups are rearranged according to a preset cross arrangement method to obtain corresponding target data packets, which may specifically include: selecting each data in the encoded data group in turn to obtain selected data; and combining the selected data in the same position in each encoded data group to obtain corresponding target data packets. The specific rearrangement process is as follows: Figure 3As shown, there are a total of T groups of encoded data groups. When these data are rearranged to obtain each target data packet, the first target data packet can select the first data in each group of encoded data groups, and the second target data packet selects the second data in each group of encoded data groups. By analogy, if there are i data in each group of encoded data groups, a total of i target data packets will be obtained, thereby dispersing the risk of network packet loss and building a data responsibility sharing mechanism. After obtaining each target data packet, the header information of the transmission protocol corresponding to the target data packet and the target meta information are combined to obtain each combined data. The target meta information here is information that characterizes the positioning information and verification information of the target data packet, which is used to inform the receiving end of the positioning information, verification information, etc. of the target data packet. It should be pointed out that the length of the combined data should be less than or equal to the length of the network maximum transmission unit, that is, the data length of the header information of the transmission protocol corresponding to the target data packet + target meta information + target data packet should be less than or equal to the length of a single MTU.

[0049] Step S13: sending each of the combined data to a receiving end at a uniform speed through a unidirectional network, so that the receiving end reorganizes each of the combined data based on the target meta information to obtain each reorganized data.

[0050] In this embodiment, when the transmitting end sends each combined data to the receiving end at a uniform speed through a unidirectional network, the data transmission rate can be determined according to the data transmission carrying capacity of the unidirectional network, and then each combined data is sent to the receiving end at a uniform speed through the unidirectional network based on the data transmission rate. Figure 3 As shown, after receiving each combined data, the receiving end reassembles each combined data based on the target meta information in each combined data to obtain each reassembled data. Specifically, the process of the receiving end reassembling the combined data is the reverse process of the process of the sending end rearranging each coded data group based on a preset cross arrangement method to obtain each target data packet. According to the positioning information in the target meta information in the combined data, the first data stored in each group of coded data groups is placed in the first position of each corresponding reassembled data, and the second data stored in each group of coded data groups is placed in the second position of each corresponding reassembled data, and so on, so as to obtain each reassembled data.

[0051] Step S14: the receiving end determines target transmission data according to each of the reorganized data, and performs corresponding verification on the target transmission data to complete data transmission.

[0052] In this embodiment, when determining the target transmission data, the receiving end can determine the redundant transmission data according to each of the reorganized data and the target redundant data, and perform grouping error correction and redundancy removal operations on the redundant transmission data according to the target meta information to obtain the target transmission data. That is, the redundant transmission data here includes the reorganized data and the target redundant data. After that, the redundant transmission data is grouped according to the meta information, and after performing redundant error correction and removing the redundancy on the grouped data, it is merged into the target transmission data in sequence, and the target transmission data is verified accordingly to complete the data transmission. Among them, the target transmission data also includes the source data and the verification data, that is, the target transmission data = source data x + verification data x, and the correctness of the source data x needs to be verified. In the verification process, if the verification data x is equal to the data after the source data x is converted into a fixed-length data string using the digest algorithm, it means that the source data x and the verification data x of the receiving end are the same as the source data and the verification data of the sending end, that is, the data is correct and the verification is successful.

[0053] like Figure 3 As shown, packet loss or data bit errors may occur when transmitting the combined data through a unidirectional network. However, since the data in each target data packet is not continuous in the source data, but is a piece of data in different data packets, the overall risk of packet loss changes from losing a whole segment of continuous data to losing one piece of data in each packet. Assuming that there are n data packets from the target network, the risk of data loss due to losing one target network data packet is reduced to 1 / n. Even if i target data packets are lost, the risk of data loss is only i / n. At the same time, the present application adopts redundant coding for the data to be transmitted. The target network data packet contains redundant data packets. Assuming that the target network data packet contains m redundant data packets, and the packet loss amount i is less than the redundant data amount m, the receiving end can restore the correct data to be transmitted through error correction calculations, such as Figure 4 After receiving the reorganized data, the receiving end performs matrix inverse operation on the redundant transmission data determined according to the reorganized data and the target redundant data. Assuming that data a2, a (i-x) , A1 is missing, and the matrices X and A are the original matrices with missing data a2 and a removed. (i-x) , A1 rows of data are formed. According to the formula X*a=A, the inverse A operation of X can be performed to obtain the original data matrix a. In this way, error correction of redundant transmission data is realized to obtain error-corrected data, and then the error-corrected and de-redundant data are sequentially merged into the new data queue to obtain the target transmission data. When correcting the errors of each reorganized data, if the redundancy ratio of the sending end in redundant encoding of the data to be transmitted is larger, the more redundant data is generated in the data to be transmitted, and the stronger the error correction capability of the receiving end when correcting the errors of each reorganized data.

[0054] In this embodiment, if the receiving end successfully verifies the target transmission data, it means that the data transmission is successful, and the receiving end can perform corresponding operations based on the target transmission data; if the receiving end fails to verify the target transmission data, it means that an abnormality has occurred during the data transmission process, and the receiving end needs to discard the target transmission data. Since the data to be transmitted constructed by the sending end is encrypted, the receiving end needs to decrypt the correctly verified source data x after obtaining the target transmission data to obtain the decrypted data.

[0055] It can be seen that the present application groups the data to be transmitted, which is composed of source data and verification data, at the sending end, and then redundantly encodes each grouped data obtained by the grouping to obtain corresponding encoded data groups, and then rearranges the data in each encoded data group according to a preset cross-arrangement method to obtain a target data packet. Since the target data packet is composed of the data in each encoded data group, the impact factor of the loss of a single data packet on the overall data is reduced, and the target data packet, the header information of the transmission protocol corresponding to the target data packet and the target meta information are combined to obtain each combined data, and each combined data is sent to the receiving end at a uniform speed through a unidirectional network, so that after receiving the target data packet, as long as the packet loss amount is less than the redundant data amount, the receiving end can reorganize and correct the target data packet based on the meta information in the target data packet to obtain the source data and verification data, and perform corresponding operations based on the obtained source data and verification data, thereby reducing the impact of the loss of a single data packet on the overall data integrity during unidirectional network communication.

[0056] Based on the above embodiment, it can be known that the present application discloses a data transmission method, which can reduce the impact of a single data packet loss on the overall data integrity during a one-way network communication. Next, the specific process of data transmission will be described.

[0057] like Figure 3 As shown, the transmitting end first constructs the data to be transmitted based on the source data and the check data, wherein the data to be transmitted is encrypted data, thereby ensuring data security during the data transmission process. Then, the data packet length is determined based on the data to be transmitted, the redundancy ratio and the MTU length, and the data to be transmitted is grouped based on the data packet length to obtain each packet data, and then each packet data is redundantly encoded based on the target redundant data, and the redundant data is attached to the corresponding packet data to obtain each encoded data group corresponding to each packet data, that is, the first group of encoded data is obtained after redundant encoding of the first group of packet data, the second group of encoded data is obtained after redundant encoding of the second group of packet data, and so on, the i-th group of encoded data is obtained after redundant encoding of the i-th group of packet data.

[0058] After obtaining each encoded data group, each data in the encoded data group is selected in turn to obtain the selected data; the selected data in the same position in each encoded data group is combined to obtain the corresponding target data packets. That is to say, the first data in the first group of encoded data groups, the first data in the second group of encoded data groups, and the first data in the last group of encoded data groups are combined to obtain the first target data packet. Similarly, the i-th target data packet contains the i-th data in each group of encoded data groups. After obtaining each target data packet, the target meta information corresponding to the target data packet, the header information of the transmission protocol corresponding to the target data packet, and the target data packet are combined to construct the combined data, wherein the target meta information does not represent the positioning information and verification information of the target data packet, and is used to inform the receiving end of the positioning information, verification information, etc. of the target data packet. It should be noted that the length of the combined data should be less than or equal to the length of the network maximum transmission unit, that is, the data length of the target data packet + target meta information + header information of the transmission protocol corresponding to the target data packet should be less than or equal to the length of a single MTU.

[0059] After obtaining the combined data, the sending end determines the data transmission rate based on the data carrying capacity of the unidirectional network, and then sends the combined data to the receiving end through the unidirectional network based on the data transmission rate. After receiving the combined data, the receiving end places the first data stored in each group of encoded data groups at the first position of each corresponding reorganized data according to the positioning information in the target meta information in the combined data, and places the second data stored in each group of encoded data groups at the second position of each corresponding reorganized data, and so on, thereby obtaining each reorganized data.

[0060] After obtaining each reorganized data, the receiving end determines the redundant transmission data according to each reorganized data and the target redundant data, groups the redundant transmission data according to the meta information, uses matrix inverse operation to correct the errors of each corresponding grouped data, and then merges the corrected and de-redundant data obtained by error correction into the new data queue in sequence to obtain the target transmission data. The target transmission data needs to be checked for correctness. If the target transmission data has completed the verification, it means that the data is correct and available, and the receiving end can perform corresponding operations based on the data; if the data has not completed the verification, the receiving end can discard the data. Since the data to be transmitted constructed by the sending end is encrypted, the receiving end needs to decrypt the source transmission data after obtaining the verified source data, so as to complete the entire data transmission process.

[0061] It can be seen that the present application groups the data to be transmitted, which is composed of source data and verification data, at the sending end, and then redundantly encodes each grouped data obtained by the grouping to obtain corresponding encoded data groups, and then rearranges the data in each encoded data group according to a preset cross-arrangement method to obtain a target data packet. Since the target data packet is composed of the data in each encoded data group, the impact factor of the loss of a single data packet on the overall data is reduced, and the target data packet, the header information of the transmission protocol corresponding to the target data packet and the target meta information are combined to obtain each combined data, and each combined data is sent to the receiving end at a uniform speed through a unidirectional network, so that after receiving the target data packet, as long as the packet loss amount is less than the redundant data amount, the receiving end can reorganize and correct the target data packet based on the meta information in the target data packet to obtain the source data and verification data, and perform corresponding operations based on the obtained source data and verification data, thereby reducing the impact of the loss of a single data packet on the overall data integrity during unidirectional network communication.
