[0030] The terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order.

[0031] As mentioned above, in the scenario of high-frequency remote procedure calls, frequent data transmission will cause great pressure on network bandwidth. This pressure is particularly obvious when the amount of data transmitted is large or similar data content is repeatedly called.

[0032] The inventor of the present invention has found that the structured data carried by the same RPC interface often has great similarity. Therefore, the present invention proposes a data transmission method and data transmission device for remote procedure call, an electronic device and a non-transient computer-readable storage medium.

[0033] According to an embodiment of the present invention, before transmitting data, the transmitted data is first divided into blocks, and the hash value of each block data is calculated. Then, the calculated hash value is compared with the hash value cached in the buffer; when the two are the same, the hash number corresponding to the block data is sent to the receiving end to replace the transmission of the block data, thereby reducing the amount of data transmission and reducing the pressure on the network bandwidth.

[0034] The specific embodiments according to the present invention are described in detail below with reference to the accompanying drawings.

[0035] Figure 1 The flowchart of a data transmission method for remote procedure call according to an exemplary embodiment of the present invention is shown. In the embodiment of the present invention, the sending end sends data to the receiving end through the remote procedure call. Figure 1 The method shown is applied to the data sending end. Figure 1 The data transmission method shown includes steps S101, S103, S105 and S107. Figure 1 Taking as an example, a data transmission method for remote procedure call according to an exemplary embodiment of the present invention is described in detail.

[0036] like Figure 1 As shown, in step S101, in response to a data transmission instruction, data to be transmitted is processed in blocks to obtain a plurality of block data, wherein the plurality of block data include a first block data.

[0037] In practice, the data to be transmitted may be processed in blocks according to preset rules, which are not specifically limited in the present invention.

[0038] For example, according to the size of the data to be transmitted, the data to be transmitted is equally divided according to a preset data block length.

[0039] For another example, according to network transmission requirements, such as network bandwidth limitations, the data to be transmitted is divided into blocks.

[0040] In step S103, a hash calculation is performed on the first block data to obtain a first hash value corresponding to the first block data.

[0041] According to an embodiment of the present invention, after obtaining the first hash value corresponding to the first block data, the first hash value and the first block data corresponding to the first hash value are stored in the cache of the sending end, so as to judge whether the transmitted data is the same as the first block data based on the calculation of the first hash value.

[0042] In step S105, the first Hash value is compared with a second Hash value pre-stored in the cache.

[0043] According to an embodiment of the present invention, before step S101, if no data has been transmitted, the cache does not store the block data and the corresponding hash value. Before step S101, if historical data has been transmitted, before step S105, the method shown in 1 further includes:

[0044] First, the historical transmission data is processed in blocks in the cache to obtain historical block data;

[0045] Then, hash calculation is performed on each historical block data to obtain the historical hash value corresponding to each historical block data;

[0046] Finally, the historical hash value and the historical block data corresponding to the historical hash value are stored in the cache; wherein the historical block data includes the first block data, and the historical hash value includes the second hash value.

[0047] In step S107, when the first Hash value and the second Hash value are equal, the first Hash number corresponding to the first Hash value is transmitted instead of transmitting the first block data.

[0048] According to an embodiment of the present invention, before step S107, it is also necessary to set the correspondence between the first hash value and the first block data in the cache of the sending end. The setting of the correspondence between the first hash value and the first block data in the cache includes:

[0049] First, a unique hash number is set for the first hash value; then, a mapping table is established for the first hash value and the first block data corresponding to the first hash value using the hash number; finally, the mapping table is stored in a cache.

[0050] For example, when historical data has been transmitted before step S101, a unique hash number is set for the historical hash value corresponding to each historical block data of the historical transmission data, and then a mapping table is established using the unique hash number, the historical block data, and the historical hash value corresponding to each historical block data, and the mapping table is stored in the cache. The historical block data includes the first block data, and the historical hash value includes the second hash value. When the historical hash value corresponding to the first hash value is retrieved from the historical hash value in step S107, only the hash number corresponding to the retrieved historical hash value is transmitted to replace the transmission of the first block data, thereby saving the amount of data transmission and reducing the pressure on network bandwidth.

[0051] according to Figure 1 In the embodiment shown, before transmitting data, the transmitted data is first divided into blocks and the hash value of each block data is calculated; then, the calculated hash value is compared with the hash value cached in the buffer; when the two are the same, the hash number corresponding to the block data is sent to the receiving end to replace the transmission of the block data, thereby reducing the amount of data transmission and reducing the pressure on the network bandwidth.

[0052] Figure 2 A flow chart of another data transmission method for remote procedure call according to an exemplary embodiment of the present invention is shown. Figure 1 compared to, Figure 2 The method shown also includes step S109. For the sake of simplicity, only step S109 is described here. Figure 1 and Figure 1 The differences between the two will not be repeated here.

[0053] In order to alleviate the storage pressure of the cache area, such as Figure 2 As shown, Figure 1 The method shown also includes step S109, counting the transmission times of the historical block data stored in the cache, and deleting the historical block data in the cache whose transmission times are less than a preset transmission times threshold.

[0054] In practice, the preset transmission number threshold can be set according to the size of the buffer area and is not limited here.

[0055] In other embodiments, step S107 may be executed regularly, and may be executed when the remaining space in the cache area is less than a preset remaining space threshold, which is not specifically limited here.

[0056] It should also be noted that the present invention does not limit the execution time of step S107. In this embodiment, step S107 is executed after step S105. In other examples, step S107 may also be executed before or after steps S101 to S105.

[0057] According to an embodiment of the present invention, before or after the sending end sends a hash number to the receiving end to replace the transmission of block data, it is also necessary to synchronize the mapping table and the corresponding historical block data to the receiving end so that the receiving end can find the block data corresponding to the hash number according to the sent mapping table.

[0058] In practice, for block data whose transmission times are greater than the preset times threshold, since the corresponding hash number has been stored at the receiving end, there is no need to synchronize the mapping table and the corresponding historical block data. However, for block data whose transmission times are less than the preset times threshold, it is necessary to synchronize the mapping table and the corresponding historical block data so that the receiving end can retrieve the corresponding block data according to the mapping table.

[0059] For example, when the block data is transmitted for the first time, the block data and the corresponding hash number need to be transmitted. The sending end stores the block data, the hash number and the corresponding hash value in its buffer at the same time. When the receiving end receives the block data, it stores the block data, the hash number and the corresponding hash value. The receiving end and the sending end synchronize the mapping table and the block data. When the block data needs to be transmitted again in the future, only the hash number of the block data needs to be transmitted, and the receiving end can find the corresponding block data according to the required number.

[0060] Figure 3 Another data transmission method flow chart for remote procedure call according to an exemplary embodiment of the present invention is shown. In the embodiment of the present invention, the sending end sends data to the receiving end through the remote procedure call, and the receiving end receives the data sent by the sending end. Figure 3 The method shown is applied to the data receiving end. Figure 3 The data transmission method shown includes steps S301, S303 and S305.

[0061] like Figure 3 As shown, in step S301, in response to a block data receiving instruction, a first hash number corresponding to a first block data is received.

[0062] When the sending end sends the first hash number to the receiving end instead of sending the first block data, the receiving end receives the first hash number corresponding to the first block data according to the block data receiving instruction.

[0063] In step S303, the first block data corresponding to the first hash number is obtained from the cache.

[0064] According to an embodiment of the present invention, before step S303, the receiving end also needs to receive the mapping table sent by the sending end and store the mapping table in the cache. The cache also stores historical block data, and the mapping table is used to store the mapping relationship between the historical block data, the historical hash value corresponding to the historical block data, and the hash number. When the receiving end executes step S303, according to the first hash number, the first block data corresponding to the first hash number is obtained from the cache. That is, according to the first hash number, the first block data corresponding to the first hash number is obtained using the mapping table.

[0065] In step S305, the transmission data sent by the transmitting end is obtained by using the first block data.

[0066] According to an embodiment of the present invention, after the receiving end obtains all the block data, it splices the block data in the splicing order to obtain the data to be transmitted in step S101. The splicing order can be determined according to the sending order of the sending end.

[0067] according to Figure 3 In the embodiment shown, the receiving end uses the cached hash number and block data and the corresponding relationship between the two to obtain the corresponding block data according to the received hash number, thereby finally obtaining the data to be transmitted by the sending end. The whole process not only reduces the amount of data transmission, but also reduces the pressure on network bandwidth.
