Fig. 1 is a flowchart of a method for transmitting disaster recovery backup data in different places, provided in the present application, applied to a primary site, as shown in fig. 1, where the method includes:
s10: judging whether the number of backup data packets to be transmitted exceeds a preset value n;
it should be noted that, when the primary station transmits data, the primary station continuously updates the data according to a set period, and each time the data is updated, a spare data packet is formed, if external interference or network fluctuation is encountered in the transmission process of the spare data packet, the transmission of the spare data packet may be blocked, so that the spare data packet to be transmitted can be better transmitted from the current primary station to the spare station, and a situation that the number of queued spare data packets to be transmitted is too many needs to be found, and whether the number of the spare data packets to be transmitted exceeds a preset value n needs to be judged. The embodiment of the application does not limit the number of preset values and the setting mode of the preset values.
S11: if yes, merging the first n backup data packets to be transmitted into a target data packet;
it should be noted that, when the number of the standby data packets to be transmitted exceeds the preset value n, the first n standby data packets to be transmitted are combined into one target data packet for transmission. In an embodiment of an application scenario, when the value of n is 10, if the number of queued standby data packets to be transmitted is greater than 10, the standby data packets to be transmitted are combined into a target data packet for transmission in sequence according to 10 groups. The numerical value of n is not specifically limited, and may be set according to actual situations, where n may be fixed or may be changed according to situations, and the embodiments of the present application are not limited herein. In addition, when the standby data packet to be transmitted does not exceed the preset value, the embodiment of the application does not limit the transmission mode of the standby data packet to be transmitted at this time, but may, but is not limited to, make the standby data packet to be transmitted currently in a waiting state, and transmit the standby data packet after merging until the number of updated standby data packets reaches the preset value, or make the standby data packet to be transmitted currently transmit separately in sequence, etc., where the embodiment of the application does not limit the transmission mode specifically, and may change according to the actual situation. In addition, the embodiment of the present application does not limit the processing of the target data packet.
S12: encoding data in a target data packet;
s13: and transmitting the target data packet subjected to the coding processing to a standby site.
It should be noted that, after the standby data packet to be transmitted is combined into the target data packet, the data in the data packet is correspondingly encoded, and the embodiment of the present application does not limit the type of encoding and the encoding mode. The embodiment of the application does not limit the processing mode of the data in the target data packet and the type of the data in the target data packet. And transmitting the data packet subjected to the coding processing to a standby station after the target data packet is formed.
Therefore, according to the method provided by the embodiment of the application, whether the number of the backup data packets to be transmitted exceeds the preset value is judged; if yes, merging the backup data packet to be transmitted into a target data packet according to the preset value, and carrying out coding processing on data in the target data packet and transmitting the data to a standby site. By the method, the queued backup data packets are combined when the number of sessions of the main station and the backup station is excessive, the data are correspondingly processed, the data transmission time is reduced, the intermediate node of the network does not have a store-and-forward function any more, the received related data information can be encoded, the processed encoded data are directly transmitted, the encoded information is played in the middle, the transmission and copying process is reduced, the network bandwidth resource consumption is saved, and the transmission efficiency is greatly improved.

judging whether the data in each backup data packet is the same or not;
if the data are the same, the redundant data are deleted.
It should be noted that, in the process of updating and transmitting data at the master site, the data in each backup data packet to be transmitted may have the same repetition, so when the backup data packets to be transmitted are combined, the same data needs to be judged, if multiple groups of data are the same, only one group of data needs to be reserved, and redundant data of the same data needs to be deleted.
Therefore, by judging whether the number of the backup data packets to be transmitted exceeds the preset value or not, the method provided by the embodiment of the application is used; if yes, merging the backup data packet to be transmitted into a target data packet according to the preset value, and carrying out coding processing on data in the target data packet and transmitting the data to a standby site. By the method, the queued backup data packets are combined when the number of sessions of the main station and the backup station is excessive, the corresponding processing is carried out on the data, the redundant data in the data packets before combination is deleted, the data transmission time is shortened, and the backup station can directly acquire the resources of the transmitted target data packets without carrying out data identification and redundant data deletion after receiving the target data packets. And the intermediate node of the network has no store-and-forward function any more, can carry out coding operation on the received related data information, and the processed coded data is directly transmitted, so that the intermediate node plays the role of coding information, reduces the process of transmission replication, saves the network bandwidth resource consumption, and greatly improves the transmission efficiency.
Based on the foregoing embodiments, the present application provides a preferred embodiment, where the encoding processing of the data in the target data packet includes:
and carrying out Hamming code encoding processing and network encoding processing on the data in the target data packet.
It should be noted that, at present, the conventional algorithm of network transmission does not reach the theoretical maximum capacity of network multicast transmission, and success or failure depends on the evaluation of each packet by the standby station when it is received, if the packet can be decoded, an acknowledgement is transmitted to the main station; otherwise, the corrupted packet is discarded and a request is sent to the primary site to resend the packet. Hamming Code (Hamming Code), a linear precoding in the field of communications, is an error correcting Code, and the Hamming Code inserts a check Code into a transmitted message stream, so that data bit errors may be generated during data transmission, single bit flip errors are detected and corrected by the Hamming Code, and in order to save network bandwidth resource consumption, improve network transmission efficiency, and need to perform network coding once during data transmission. The embodiment of the application is not limited to the two encoding processing modes, and can be selected or changed according to actual situations. The embodiments of the present application do not limit the specific manner of network coding. In addition, the embodiment of the application does not limit the processing sequence of hamming code encoding and network encoding, and the target data packet can be subjected to hamming code encoding processing first or network encoding processing first and can be selected according to actual conditions.

Based on the foregoing embodiments, the present application provides a preferred embodiment, where performing network coding processing on data in a target data packet includes:
and carrying out linear coding or nonlinear coding processing on the data in the target data packet.
In order to save network bandwidth resource consumption and improve network transmission efficiency, it is necessary to perform network coding once when transmitting data. The conventional network routing mechanism considers that the intermediate node only needs to simply store and forward the transmitted information, and does not need to perform any processing. However, none of the conventional algorithms reach the theoretical maximum capacity of network multicast transmission. The network coding thoroughly overrides the traditional point, the intermediate node of the network not only has a store-and-forward function, but also can perform linear or nonlinear coding operation on the received related information, and the processed coded data is transmitted. The embodiment of the application is not limited to only include two processing modes of linear coding and nonlinear coding, and can be changed according to actual conditions.
It can be seen that, in the method provided in this embodiment, whether the number of backup data packets to be transmitted exceeds a preset value is determined; if yes, merging the backup data packet to be transmitted into a target data packet according to a preset value, carrying out Hamming code encoding processing and linear encoding or nonlinear encoding processing on data in the target data packet, and transmitting the data to a standby site. By the method, the intermediate node of the network has no store-and-forward function, can perform linear coding or nonlinear coding operation on the received related data information, and the processed coded data is directly transmitted, so that the intermediate node plays a role in coding information, reduces the transmission and copying process, saves the network bandwidth resource consumption, and greatly improves the transmission efficiency and reliability.
Based on the foregoing embodiments, the present application provides a preferred embodiment, where the preset value n is a fixed value or is set according to the number of backup data packets.
It should be noted that, the value of the preset value n may be a fixed value, or may be set according to the value count of the backup data packets to be transmitted, that is, when the number of the backup data packets is too large, the value of the preset value may be correspondingly increased. The embodiment of the application is not limited to the two setting modes, and may be set to a dynamic preset value or the like, and may be selected according to actual situations.
It can be seen that, by the method provided in this embodiment, whether the number of backup data packets to be transmitted exceeds a preset value is determined; if yes, merging the backup data packet to be transmitted into a target data packet according to the preset value, and carrying out coding processing on data in the target data packet and transmitting the data to a standby site. By the method, the queued backup data packets are combined when the number of sessions of the main station and the backup station is excessive, the data are correspondingly processed, the data transmission time is reduced, the intermediate node of the network does not have a store-and-forward function any more, the received related data information can be encoded, the processed encoded data are directly transmitted, the encoded information is played in the middle, the transmission and copying process is reduced, the network bandwidth resource consumption is saved, and the transmission efficiency is greatly improved.
On the basis of the foregoing embodiment, the present application provides a preferred embodiment, where determining whether the number of backup data packets to be transmitted exceeds the preset value n further includes:
and if the number of the backup data packets to be transmitted does not exceed the preset value n, sequentially encoding each backup data packet and transmitting the backup data packets to a standby site.
It should be noted that, when the number of the backup data packets to be transmitted does not exceed the preset value n, that is, the number of the backup data packets to be transmitted does not reach the combined value, in order to avoid interruption of data transmission, and the queued data packets at this time do not affect normal transmission, each backup data packet is sequentially encoded and transmitted to the backup site. The embodiment of the application is not limited to the transmission mode, and can be selected according to actual situations.
Therefore, by judging whether the number of the backup data packets to be transmitted exceeds the preset value or not, the method provided by the embodiment of the application is used; if yes, merging the backup data packet to be transmitted into a target data packet according to the preset value, and carrying out coding processing on data in the target data packet and transmitting the data to a standby site. By the method, the queued backup data packets are combined when the number of the session times of the main station and the backup station is excessive, the data are correspondingly processed, the data transmission time is shortened, the backup data packets are sequentially and singly transmitted when the number of the backup data packets does not reach a preset value, the condition of transmission failure in the waiting process is avoided, the interruption of data transmission is avoided, and the transmission efficiency and reliability are greatly improved.
