[0002] With the rapid development of the social economy and the continuous improvement of people's living standards, data communication technology has been widely popularized and applied in all walks of life. The data transmission volume has entered an era of unprecedented growth. Moreover, the types of information content that people can access are becoming increasingly rich and colorful, and the size of data blocks in the data transmission process is correspondingly getting larger and larger.

[0003] Data, that is, files in a device with data storage capacity, is usually transmitted through a network using a certain established data transmission protocol. Among them, the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol is one of the most commonly used data transmission protocols. At present, the requirements for data transmission efficiency in the market are getting higher and higher. If data is still transmitted according to the initial size of the data block during TCP / IP transmission, the data transmission efficiency will be severely reduced. Summary of the Invention

[0017] In a third aspect, an embodiment of the present application provides an electronic device, including a processor, a memory, and computer execution instructions stored on the memory and executable on the processor. When the computer execution instructions are run, the electronic device is caused to execute some or all of the steps described in any method of the first aspect of the embodiments of the present application.

[0018] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, in which computer instructions are stored. When the computer instructions are run on a communication device, the communication device is caused to execute some or all of the steps described in any method of the first aspect of the embodiments of the present application.

[0019] In a fifth aspect, an embodiment of the present application provides a computer program product, where the computer program product includes a computer program, and the computer program is operable to cause a computer to execute some or all of the steps described in any method of the first aspect of the embodiments of the present application.

[0022] Determining a digital equivalent, which is determined by the TCP / IP connection establishment process between the sender and the receiver;

[0026] It can be seen that in the embodiments of the present application, the digital equivalent is determined by the TCP / IP connection establishment process between the sender and the receiver, and then the first functional relationship satisfied by the value of the first data shard and the data equivalent is determined.

By using the method of the embodiments of the present application, during the TCP / IP transmission process, the coding information is determined and sent in the data dictionary according to the functional relationship satisfied by the value of the data shard and the data equivalent. Since only the coding information needs to be sent instead of the data blocks that occupy a large amount of space, a large amount of data transmission volume is reduced, thereby improving the data transmission efficiency.

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0038] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps is not limited to the listed steps, but optionally further includes steps not listed, or optionally further includes other steps inherent to these processes, methods, products or devices.

[0039] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0040] The application scenarios related to the embodiments of the present application are introduced below in conjunction with the accompanying drawings.

[0041] Figure 1 It is a structural deployment diagram of a data transmission system. As Figure 1 shown, the first end of the system is connected to the sending end and the second end is connected to the receiving end.

[0042] Among them, the sending end refers to the role that wants to send the original data to the receiving end and thus send the original data to the data transmission system for compression;

[0043] Among them, the data transmission system is used to receive the original data from the sending end, compress the original data through a traditional compression algorithm, and send the compressed original data to the receiving end;

[0044] Among them, the receiving end refers to the role that receives the compressed original data from the data transmission system and restores the compressed original data to obtain the original data;

[0045] During the data transmission process of the above system, since the original data is only compressed by traditional compression algorithms, new compression redundancy will be generated. Moreover, the compression effect of traditional compression algorithms on data blocks with large occupied space is limited. It can be seen that the above process does not have a sufficient improvement effect on data transmission efficiency.

[0046] Based on this, the embodiments of the present application provide a function-based data sending method, which is applied to the sending end. Please refer to Figure 2 , Figure 2 is a schematic flowchart of a function-based data sending method provided by the embodiments of the present application. As Figure 2 shown, the method includes the following steps:

[0047] 101: Obtain the data to be sent and split the data to be sent into X data shards.

[0048] Among them, the data to be sent can be decimal data. In a specific implementation, the binary data corresponding to the original data can be converted into decimal data through the number system to obtain the data to be sent. The data forms of the original data include forms such as numbers, texts, symbols, images, voices, videos, etc.

[0049] Among them, for the X data shards, if the data to be sent is decimal data, each of the X data shards obtained by corresponding splitting should also be decimal data.

[0050] Among them, splitting the data to be sent into X data shards can be splitting it into multiple data shards of the same size or splitting it into multiple data shards of different sizes.

[0051] 102: Determine the digital equivalent, which is determined by the TCP / IP connection establishment process between the sending end and the receiving end.

[0052] Among them, TCP / IP (Transmission Control Protocol / Internet Protocol) refers to the communication protocol for networking communication between computers, which defines how computers and other electronic devices are networked and the standards for how data is transmitted between them.

[0053] Please refer to Figure 3 , Figure 3 is an example schematic diagram of the TCP / IP connection establishment process. As Figure 3As shown, during the TCP / IP transmission process, the sender and the receiver use the three-way handshake method to confirm the successful establishment of the connection between the two parties. In the first handshake, the sender generates a synchronization sequence number, which includes a synchronization flag SYN (synchronous) = 1 and a synchronization sequence number SynNumber. The sender sends the synchronization sequence number and the first random sequence number SEQ1 (Sequence number) = x to the receiver; in the second handshake, the receiver receives the synchronization sequence number and knows from SYN = 1 in the synchronization sequence number that the sender requests to establish a connection. Therefore, the receiver sends an acknowledgement flag ACK (acknowledgement) = 1 and SYN = 1 to the sender, and sends the first acknowledgement number ACKnumber1 (Acknowledge number) = x + 1 to the sender according to SEQ1, and then randomly generates a second random sequence number SEQ2 = y and sends it to the sender; in the third handshake, the sender checks whether the received ACKnumber1 is correct, that is, checks whether ACKnumber1 is equal to SEQ1 + 1, that is, x + 1, and whether ACK is 1. If so, the sender sends ACK = 1 and the second acknowledgement number ACKnumber2 = y + 1 to the receiver. The receiver confirms whether ACKnumber2 is equal to SEQ2 + 1, that is, y + 1, and whether ACK is 1. If so, the sender and the receiver successfully establish a data transmission connection.

[0054] Among them, the digital equivalent is determined by the TCP / IP connection establishment process between the sender and the receiver. It can refer to that the digital equivalent is determined respectively according to the first digits of the synchronization sequence number SynNumber, the first acknowledgement number ACKnumber1, and the second acknowledgement number ACKnumber2 generated during the TCP / IP connection establishment process. Since the first digits of SynNumber, ACKnumber1, and ACKnumber2 may all be 0-9, the possible values of the digital equivalent are 000-999. That is to say, there are 1000 possible values for the digital equivalent. Since the numbers generated during the above connection establishment process will not change until the connection is disconnected after the connection between the sender and the receiver is successfully established, there is only one digital equivalent during a single connection establishment process. Therefore, the sender and the receiver jointly correspond to the same digital equivalent.

[0055] 103: Obtain the first data fragment among X data fragments and determine the first functional relationship satisfied by the value of the first data fragment and the digital equivalent.

[0056] Among them, the first data fragment can be any one of the X data fragments.

[0057] Among them, determining the first functional relationship satisfied by the value of the first data shard and the data equivalent item. In specific implementation, it can refer to the functional relationship where the arithmetic formula holds when the data equivalent item is used as the independent variable and the value of the first data shard is used as the dependent variable, or it can also refer to the functional relationship where the arithmetic formula holds when the value of the first data shard is used as the independent variable and the data equivalent item is used as the dependent variable.

[0058] Exemplarily, the first functional relationship refers to the functional relationship where the arithmetic formula holds when the data equivalent item is used as the independent variable and the value of the first data shard is used as the dependent variable. If the value of the first data shard is 256 and the data equivalent item is 004, considering 004 as 4, since 4 4 = 256, in this case, the first functional relationship is: the value of the data shard is the value of the power function with the data equivalent item as the base and 4 as the exponent. It can be obtained that the first functional relationship is: the value of the data shard = (data equivalent item) 4 .

[0059] Another exemplarily, similarly, the first functional relationship refers to the functional relationship where the arithmetic formula holds when the data equivalent item is used as the independent variable and the value of the first data shard is used as the dependent variable. If the value of the first data shard is 28657 and the data equivalent item is 023, considering 023 as 23, since in the Fibonacci sequence when the independent variable is 23 the dependent variable is 28657, then in this case, the first functional relationship is: the value of the data shard is the value of the Fibonacci sequence with the data equivalent item as the number of terms. It can be obtained that the first functional relationship is:

[0060] 104: Obtain the first coding information of the first functional relationship in the data dictionary. The data dictionary includes coding information corresponding to multiple functional relationships.

[0061] Among them, the first coding information of the first functional relationship in the data dictionary can be the size of 4 bits. That is to say, the number of space bits occupied by the first coding information can be 4 bits. In specific implementation, the number of space bits occupied by the first coding information can be specifically determined according to the number of the first functional relationships. The fewer the number of the first functional relationships, the smaller the number of space bits occupied by the first coding information.

[0062] Exemplarily, based on the above exemplary embodiments, if the first coding information is 4 bits and the data dictionary includes coding information corresponding to multiple functional relationships. In a specific implementation, it can be that when the first functional relationship is that the value of the data shard is the value of a power function with the data equivalent term as the base and 4 as the exponent, the corresponding first coding information is 0001; when the first functional relationship is that the value of the data shard is the value of the Fibonacci sequence with the data equivalent term as the number of terms, the corresponding coding information is 0101. It should be noted that the coding information corresponding to the functional relationship described in this exemplary embodiment in the data dictionary is only an example. In a specific application, the coding information corresponding to the functional relationship in the data dictionary can also exist in other coding forms.

[0063] 105: Send the first coding information.

[0064] Among them, if the first data shard is one of the X data shards, there is a one-to-one correspondence between the first coding information and the first data shard. When the first coding information is sent X times, the sending end successfully sends the data to be sent to the receiving end. After that, the receiving end only needs to restore each of the X first coding information to obtain X data shards, and then splice the X data shards to restore the data to be sent.

[0065] Exemplarily, please refer to Figure 4 , Figure 4 which is an example schematic diagram of a data sending method based on functions provided by an embodiment of the present application. As Figure 4As shown in the figure, assume that the number of bits occupied by the first coding information is 4 bits, and the original data is 00100110100001010111... After converting the original data to decimal, the decimal data, i.e., the data to be sent, is 28657... The server obtains the data to be sent from the sending end and splits the data to be sent into X data shards. If the first digits of SynNumber, ACKnumber1, and ACKnumber2 generated during the TCP / IP connection establishment process between the sending end and the receiving end are 0, 2, and 3 respectively, then the server determines that the digital equivalent is 023, and obtains the first data shard as 26857 among the X data shards. Since in the Fibonacci sequence, the sequence value corresponding to the term number 23 is 26857, therefore, the server determines that the first function relationship satisfied by the value of the first data shard and the digital equivalent is: the value of the data shard is the value of the Fibonacci sequence with the digital equivalent as the term number. And the first coding information of the first function relationship in the data dictionary is 0101, then the server sends the first coding information, that is, sends 0101 to the receiving end; Similarly, for the remaining data, the server can send the remaining coding information in the same way. It can be seen that if the method of this application embodiment is not adopted, then the original sending data corresponding to the data shard 28657 should be 00100110100001010111, which occupies 20 bits of space. After adopting the method of this application embodiment, only the first coding information that occupies 4 bits or other fewer bits of space needs to be sent. Even for data shards that occupy more space and larger space, only 4 bits or other fewer bits of the first coding information need to be sent. Obviously, the method of this application embodiment significantly reduces the amount of data to be sent for data shards that occupy a large amount of space, and greatly improves the data transmission efficiency.

[0066] It can be seen that in the embodiment of this application, the digital equivalent is determined by the TCP / IP connection establishment process between the sending end and the receiving end, and then the first function relationship satisfied by the value of the first data shard and the digital equivalent is determined, so as to obtain the first coding information of the first function relationship in the data dictionary and send the first coding information, and finally complete the sending of X data shards by sending X coding information. By adopting the method of this application embodiment, during the TCP / IP transmission process, the coding information is determined and sent in the data dictionary according to the function relationship satisfied by the value of the data shard and the digital equivalent. Since only the coding information needs to be sent instead of the data block that occupies a large amount of space, a large amount of data transmission volume is reduced, thereby improving the data transmission efficiency.

[0067] In a possible example, the above method further includes:

[0068] Send the data dictionary;

[0069] Or send the identification information of the data dictionary, where the identification information of the data dictionary characterizes the data dictionary corresponding to X pieces of first coding information.

[0070] Wherein, the data dictionary occupies a space of a coding space, and the occupied space of the coding space and the X pieces of first coding information is smaller than the occupied space of sending X data shards.

[0071] In a specific implementation, the data transmission volume of sending the identification information of the data dictionary is smaller than the data transmission volume of directly sending the data dictionary. If the receiving end locally stores the data dictionary, the method of sending the identification information of the data dictionary can be adopted to further improve the data transmission efficiency.

[0072] It can be seen that in the embodiments of the present application, by sending the data dictionary or the identification information of the data dictionary, the data conversion basis between the X pieces of first coding information sent and the X data shards is informed to the receiving end, so that the receiving end can restore the X pieces of first coding according to the data dictionary to obtain the original data corresponding to the data to be sent.

[0073] In a possible example, the above method further includes:

[0074] Obtain the first possible value of the digital equivalent;

[0075] Obtain the second possible value of the first data shard;

[0076] Determine at least one functional relationship that the first possible value and the second possible value can satisfy;

[0077] Encode at least one functional relationship to obtain coding information, and obtain a data dictionary according to the coding information.

[0078] Wherein, for the first possible value of the digital equivalent, if it is determined by the first digits of the synchronization sequence number SynNumber, ACKnumber1, and ACKnumber2 generated respectively during the TCP / IP connection establishment process for the digital equivalent, then as can be seen from the above, the first possible value of the digital equivalent is 1000 possible values from 000 to 999.

[0079] Wherein, the second possible value of the first data shard is determined by the number of bits of the occupied space of the first data shard.

[0080] Exemplarily, if the first data shard is decimal data, when the number of bits of the occupied space of the first data shard is 3 bits, the second possible value of the first data shard is 1000 possible values from 0 to 999; if the number of bits of the occupied space of the first data shard is 5 bits, the second possible value of the first data shard is 100000 possible values from 0 to 99999.

[0081] Among them, determining at least one functional relationship that the first possible value and the second possible value can satisfy may be determining at least one functional relationship that can be satisfied when the first possible value is the independent variable and the second possible value is the dependent variable, or may be determining at least one functional relationship that can be satisfied when the first possible value is the dependent variable and the second possible value is the independent variable.

[0082] Exemplarily, please refer to Figure 5 , Figure 5 FIG. is a schematic diagram of an example of a data sending method based on a function provided by an embodiment of the present application. As Figure 5 shown, if it is determined that the functional relationships that the first possible value and the second possible value can satisfy are functional relationship 1, functional relationship 2... functional relationship N, then functional relationship 1 is encoded as encoding information 1, functional relationship 2 is encoded as encoding information 2... functional relationship N is encoded as encoding information N, so as to obtain a data dictionary including the N encoding information corresponding to the above N functional relationships.

[0083] It can be seen that in the embodiment of the present application, by obtaining the first possible value of the digital equivalent and the second possible value of the first data shard, determining at least one functional relationship that the first possible value and the second possible value can satisfy, encoding at least one functional relationship to obtain encoding information, and then obtaining a data dictionary according to the encoding information. Thus, when there is already a given digital equivalent in the TCP / IP transmission process, through the functional relationship, there is a data conversion basis for one-to-one correspondence between each of the X data shards and the encoding information. In a possible example, the above encoding at least one functional relationship to obtain encoding information includes:

[0084] Obtaining the first identifier of each functional relationship in at least one functional relationship;

[0085] Obtaining the encoding information of each functional relationship in at least one functional relationship, where the encoding information includes the binary value corresponding to the first identifier.

[0086] Exemplarily, if the first identifier of a functional relationship is the decimal data 5, and the decimal data 5 is converted to binary data 0101 through binary conversion, then the encoding information of this functional relationship is 0101.

[0087] It can be seen that in the embodiment of the present application, the encoding information of each functional relationship in at least one functional relationship is the binary data corresponding to the first identifier of each functional relationship, and the encoding information is represented in the form of binary data to facilitate the direct sending of the encoding information.

[0088] In a possible example, the above method further includes:

[0089] Obtain a second identifier, where the second identifier is used to represent the difference between the value of each function relationship in at least one function relationship and the second possible value of the first data shard when the first possible value of the digital equivalent and the second possible value of the first data shard satisfy at least one function relationship;

[0090] Obtain the second identifier corresponding to the difference;

[0091] The encoding the at least one function relationship to obtain encoding information includes:

[0092] Obtain the encoding information of each function relationship in the at least one function relationship, where the encoding information includes the binary values corresponding to the first identifier and the second identifier.

[0093] Among them, the difference can be the value obtained by subtracting the second possible value of the first data shard from the value of the function relationship, or the value obtained by subtracting the value of the function relationship from the second possible value of the first data shard.

[0094] Among them, if the existing difference is only a positive number, the number of bits occupied by the second identifier corresponding to the remainder can be 2 bits, 4 bits, or other numbers of bits.

[0095] Exemplarily, if the existing difference is only a positive number, when the number of bits occupied by the second identifier is 2 bits, 00 can represent a difference of 0, 01 can represent a difference of 1, 10 can represent a difference of 2, and 11 can represent a difference of 3. That is to say, it can represent a total of 4 differences from 0 to 3; when the number of bits occupied by the second identifier is 4 bits, similarly, it can represent a total of 16 differences from 0 to 15.

[0096] Among them, if the existing difference includes both positive and negative numbers, the space occupied by the second identifier corresponding to the remainder can be 3 bits, 5 bits, or other numbers of bits.

[0097] Exemplarily, if the existing difference includes both positive and negative numbers, the first bit of the second identifier is used to represent the positive or negative of the difference. For example, 0 is used to represent a positive difference and 1 is used to represent a negative difference. When the number of bits occupied by the second identifier is 3 bits, 000 to 011 can represent differences from 0 to 3, and 101 to 111 can represent (-1) to (-3), a total of 8 differences; when the number of bits occupied by the second identifier is 5 bits, similarly, 00000 to 01111 can represent 0 to 15, and 10001 to 11111 can represent (-1) to (-15), a total of 32 differences.

[0098] Among them, the encoding information is formed by connecting the binary data corresponding to the first identifier and the second identifier adjacent to each other. That is to say, the binary data corresponding to the second identifier can be located in front of or behind the first identifier.

[0099] Exemplarily, based on the above exemplary embodiments, when the difference is only a positive number, the number of bits occupied by the second identifier corresponding to the remainder is 2 bits, and the binary data corresponding to the second identifier is in front of the first identifier. If the first data shard is 255, the digital equivalent is 4, and the functional relationship satisfied by the first possible value of the digital equivalent and the second possible value of the first data shard is: value of the functional relationship = (digital equivalent) 4 , since 4 4 = 256, and 256 - 255 = 1. It can be seen that the difference is 1, so the second identifier corresponding to the difference is 01. Thus, in this case, the encoded information can be obtained as 010001, and this encoded information can represent that when the value of the first data shard is incremented by 1, the functional relationship can be satisfied: value of the data shard = (digital equivalent) 4 .

[0100] It can be seen that in the embodiments of the present application, when the value of the first data shard can satisfy a certain functional relationship with the digital equivalent only after the difference within a certain range is increased or decreased, the binary value corresponding to the second identifier corresponding to the difference and the first identifier are obtained to form the encoded information. Thus, when there is a predetermined digital equivalent during the TCP / IP transmission process, even when there is a certain deviation between the value of the first data shard and the functional relationship, the encoded information can accurately represent the value of the first data shard, so that there is a data conversion basis for one-to-one correspondence between each of the X data shards and the encoded information.

[0101] In a possible example, the number of bits occupied by each encoded information is less than the number of bits occupied by each of the X data shards.

[0102] Among them, the number of bits occupied by each of the X data shards can refer to the number of bits occupied when each data shard is a decimal data, or can refer to the number of bits occupied after each data shard is converted from decimal data to binary data. Obviously, the number of bits occupied by binary data is greater than the number of bits occupied by decimal data.

[0103] It can be seen that in the embodiments of the present application, by ensuring that the number of bits occupied by each encoded information is less than the number of bits occupied by each of the X data shards, when sending the content of the data shard by sending the encoded information, the data transmission volume is less than the data transmission volume when directly sending the data shard, thereby improving the data transmission efficiency.

[0104] In a possible example, if the first functional relationship satisfied by the value of the first data shard and the data equivalent is a combination of multiple functional relationships, the obtaining of the first encoded information of the first functional relationship in the data dictionary includes:

[0105] Obtain the combination ways of multiple functional relationships and the coding information of each functional relationship in the multiple functional relationships;

[0106] Obtain first coding information, where the first coding information includes the coding information of each functional relationship in the multiple functional relationships and the coding information of the combination way of the multiple functional relationships.

[0107] Among them, the combination way of functional relationships refers to the operation rules between functional relationships, and the operation rules include addition, subtraction, multiplication, division or other rules. If the operation rules are only the four types of addition, subtraction, multiplication, and division, the coding information of the combination way of functional relationships can be represented by 2-bit binary data.

[0108] Among them, the arrangement way of the coding information of each functional relationship included in the first coding information and the coding information of the combination way of the multiple functional relationships can be, in specific implementation, arranged in sequence according to the combination way of the multiple functional relationships and the operation rules therebetween.

[0109] Exemplarily, please refer to Figure 6 , Figure 6 which is a schematic diagram of an example of a data sending method based on functions provided by an embodiment of the present application. As Figure 6 shown, if the first functional relationship satisfied by the value of the first data shard and the data equivalent item is: functional relationship 1 ÷ functional relationship 2, where the coding information of functional relationship 1 is 0001, the coding information of functional relationship 2 is 0101, and the operation rule of division is represented by binary data 11, then the first coding information can be 0001110101.

[0110] It can be seen that in the embodiment of the present application, when the first functional relationship satisfied by the value of the first data shard and the data equivalent item is a combination of multiple functional relationships, by obtaining the combination ways of the multiple functional relationships and the coding information of each functional relationship in the multiple functional relationships, the first coding information includes the coding information of each functional relationship in the multiple functional relationships and the coding information of the combination way of the multiple functional relationships. Thus, the first functional relationship can represent more corresponding functional relationships between the value of the first data shard and the data equivalent item, improve the coverage range of the value of the numerical shard by the first functional relationship, and further reduce the number of functional relationships. Correspondingly, the number of coding information included in the data dictionary also decreases, and in some possible cases, it can play a role in reducing the space size occupied by the first coding information and further improving the data transmission efficiency.

[0111] Consistent with the above Figure 2 shown embodiment, please refer to Figure 7 , Figure 7 which is a schematic structural diagram of a data sending device based on functions provided by an embodiment of the present application. As Figure 7 shown:

[0112] A function-based data sending device is applied to a sending end. The device includes:

[0113] 201: An acquisition unit, configured to acquire data to be sent and split the data to be sent into X data shards.

[0114] 202: A digital unit, configured to determine a digital equivalent, which is determined by the TCP / IP connection establishment process between the sending end and the receiving end.

[0115] 203: A function unit, configured to acquire a first data shard among the X data shards and determine a first functional relationship satisfied by the value of the first data shard and the data equivalent.

[0116] 204: An encoding unit, configured to acquire first encoding information of the first functional relationship in a data dictionary, where the data dictionary includes encoding information corresponding to multiple functional relationships.

[0117] 205: A sending unit, configured to send the first encoding information.

[0118] It can be seen that in the device provided in the embodiment of the present application, the digital equivalent is determined by the TCP / IP connection establishment process between the sending end and the receiving end, and then the first functional relationship satisfied by the value of the first data shard and the data equivalent is determined, so as to acquire the first encoding information of the first functional relationship in the data dictionary and send the first encoding information, and finally complete the sending of the X data shards by sending X encoding information. By using the device in the embodiment of the present application, during the TCP / IP transmission process, the encoding information is determined and sent in the data dictionary according to the functional relationship satisfied by the value of the data shard and the data equivalent. Since only the encoding information needs to be sent instead of the large data blocks that occupy a large space, a large amount of data transmission volume is reduced, thereby improving the data transmission efficiency.

[0119] Specifically, the embodiment of the present application can divide the function units of the function-based data sending device according to the above method example. For example, each function unit can be corresponding to each function, or two or more functions can be integrated into one processing unit.

Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily essential to the present application.

[0133] The foregoing Figure 2 The embodiments shown are applied to the sending end. For the corresponding receiving end, an embodiment of the present application provides a function-based data receiving method, which is applied to the receiving end. Please refer to Figure 9 , Figure 9 which is a schematic flowchart of a function-based data receiving method provided by an embodiment of the present application. As Figure 9 shown, the method includes the following steps:

[0134] 301: Receive X encoded messages.

[0135] 302: Determine the digital equivalent, which is determined by the TCP / IP connection establishment process between the sending end and the receiving end.

The target function relationship is determined in the data dictionary according to each of the X coding information, and then X data shards are obtained according to the target function relationship and the digital equivalent. Finally, the original data can be obtained by splicing the multiple data shards.
