Referring to fig. 1, a flow chart of one embodiment of a data transmission method according to the present disclosure is shown. As shown in fig. 1, the data transmission method includes the following steps S101 to S103.
Step S101, the application program obtains the network state parameter of the current time.
The network status parameters of the used network can be obtained in real time. The network used herein may be a wired network and a wireless network. The wireless network may include, but is not limited to, a 2G network, a 3G network, a 4G network, and a 5G network.
The application program may be, for example, a chat application program or an application program that can substantially receive a user information transmission instruction.
The network state parameters are used for characterizing the network state of the used network. Here, the network status parameters may include, for example: network transmission rate, data transmission delay, etc.
Wherein, the network transmission rate may be obtained based on the procedure shown in fig. 2. Referring to fig. 2, the obtaining of the network transmission rate includes the following steps:
in step S201, the application program obtains the transmission data amount in a preset time period before and adjacent to the current time.
The preset time period may include, but is not limited to, 30 seconds, 1 minute, 2 minutes, 5 minutes.
Here, when the transmission data amount in the preset time period is acquired, timing may be started from the time when the transmission data amount starts to be acquired according to the duration of the preset time period, and the acquisition operation may be ended at the corresponding termination time after the duration, that is, the transmission data amount in the preset time period may be counted.
Step S202, based on the transmission data volume and the duration of the preset time period, the network transmission rate of the previous preset time period is obtained, and the network transmission rate of the previous preset time period is the current network transmission rate.
Specifically, the quotient of the transmission data amount in the preset time period and the duration of the preset time period may be used to obtain the network transmission rate. The duration of the preset time period may be set to be relatively short, for example, 30 seconds or 20 seconds, so that the network transmission rate obtained according to the data amount transmitted in the previous preset time period may be regarded as the real-time network transmission rate at the current time.
Step S102, the network state parameters and the data to be sent at the current moment are sent to a preset data splitting component, and the preset data splitting component executes data splitting operation.
The data to be transmitted may be data corresponding to pictures, texts, or videos. For the same data to be sent, if the network state parameters at different times are different in the sending process, the lengths of the data packets corresponding to the data to be sent at the different times may also be different.
The preset data splitting component can be an execution control for data splitting between the application program and the system network layer.
The data splitting operation can be divided into the following three steps:
the method comprises a first operation of determining whether the network state parameter meets a preset network state parameter condition.
The preset network state parameter condition may include, for example, whether the network transmission rate is greater than a preset network transmission rate threshold, and/or whether the data transmission delay is smaller than a preset data transmission delay threshold.
And a second operation of determining that the current network state is the weak network state in response to determining that the network state parameter does not satisfy the preset network state parameter condition.
In some application scenarios, the preset network transmission rate threshold may be 1 Mbps. If the network transmission rate is greater than the preset network transmission rate threshold, the network state can be determined to be a normal network state. If the network transmission rate is less than the preset network transmission rate threshold, the network state can be determined to be a weak network state.
In these application scenarios, if the current network transmission rate is less than 1Mbps, it may be determined that the current network state is a weak network state.
It should be noted that the preset network transmission rate threshold may be set according to different application scenarios. And are not limited herein.
In other application scenarios, the data transmission delay threshold may be 5s, for example. And if the data transmission delay is smaller than the preset data transmission delay threshold, determining that the network state is a normal network state. If the data transmission delay is greater than the preset data transmission delay threshold, the network state can be determined to be a weak network state.
In these application scenarios, if the current data transmission delay is greater than 5s, it may be determined that the current network state is a weak network state.
And thirdly, splitting the data to be sent into at least two split data according to a splitting rule corresponding to the network state parameter.
The data to be transmitted may be data corresponding to pictures, texts, or videos. For the same data to be sent, if the network state parameters at different times are different in the sending process, the lengths of the data packets corresponding to the data to be sent at the different times may also be different.
The splitting rule here may be to split the data to be transmitted according to a bisection method. For example, if a certain piece of information with ten words is sent as data to be sent, the data corresponding to the piece of information may be divided into two pieces of split data equally and sent, that is, each piece of split data may include five words.
In some alternative implementations, as shown in fig. 3, the third operation may include the following steps:
step S301, matching the network state parameters with a preset network state-data packet mapping relation table, wherein the preset network state-data packet mapping relation table stores multiple groups of network state parameters and data packet lengths corresponding to each group of network state parameters in an associated manner.
In some application scenarios, the network status-packet mapping relationship table includes a plurality of packet lengths and a plurality of sets of network status parameters, and the packet lengths corresponding to different network status parameters are different.
The length of the data packet corresponding to each group of network state parameters can be determined by the following steps:
firstly, obtaining a plurality of sending messages of splitting data packets which are sent successfully in history, wherein the sending messages comprise data packet lengths and sending time delays.
Secondly, the sending efficiency corresponding to each of the plurality of split data which are sent successfully in the history is determined, and the length of the split data packet with the highest sending efficiency is determined as the data packet length corresponding to the group of network state parameters.
The transmission efficiency here may be determined according to the amount of data transmitted per unit time. For example, splitting data to be sent according to a data packet length of 1000 bytes, and if the time length of the split data from the beginning to the end of sending is 40 seconds, then the sending efficiency at this time is (1000/40) bytes/second; splitting data to be sent according to the length of a data packet being 900 bytes, wherein if the time length of the split data after being sent to the sending completion is 30 seconds, the sending efficiency at the moment is (900/30) bytes/second. Then 900 bytes can be split as the packet length of the data to be transmitted under the condition that the network transmission rate is the same. That is, the length of the data packet corresponding to the set of network state parameters may be 900 bytes.
In this embodiment, the network status-packet mapping table may be queried according to the network status parameter, so as to determine whether a packet length corresponding to the network status parameter exists in the network status-packet mapping table.
Step S302, if the matching is successful, splitting the data to be transmitted according to the data packet length corresponding to the network state parameter in the preset network state-data packet mapping relation table.
That is, if the packet length corresponding to the network status parameter is found in the network status-packet mapping table, it can be determined that the packet length corresponding to the network status parameter exists in the network status-packet mapping table. The length of the data packet can be used as the length of the data packet corresponding to the current time, and the data to be sent is split according to the length of the data packet.
In some optional implementations, the third operation may further include:
step S303, if the matching is unsuccessful, determining the data packet length successfully transmitted within the preset transmission delay as the data packet length corresponding to the splitting data according to the network state parameter at the current moment, and splitting the data to be transmitted according to the data packet length; and the network state parameter and the data packet length at the current moment are related and stored in a network state-data packet mapping relation table.
That is, if it is determined in step S301 that the network state parameter at the current time does not exist in the network state-packet mapping table and/or the packet length corresponding to the network state parameter at the current time does not exist, the packet length successfully transmitted within the preset transmission delay is determined as the packet length corresponding to the current time.
The preset transmission delay is a preset time length from the beginning to the end of transmission of the data to be transmitted, and may be, for example, 5 to 30 seconds, 1 to 3 minutes, and the like.
The network state parameter and the data packet length at the current moment are related and stored in a network state-data packet mapping relation table, so that the information capacity of the network state-data packet mapping relation can be increased, and the network state-data packet mapping relation table can be directly inquired next time.
In some optional implementations, the third operation may further include:
step S304, if the length of a data packet generated by splitting the data to be transmitted according to the current network state parameters is less than or equal to a preset splitting threshold, splitting the data to be transmitted by taking the splitting threshold as the length of the data packet corresponding to the split data; wherein the split threshold is the length of the minimum transmission data packet.
That is to say, if the length of the split data packet obtained by splitting the data to be transmitted is smaller than or equal to the preset split threshold under the network state parameter at the current time, the split data cannot be split again. And the preset splitting threshold value can only be used as the length of the split data packet to split the data to be sent. The preset splitting threshold here may be, for example, 64 bytes, 128 bytes, and the like.
In some optional implementations, the data splitting operation may further include the following adjustment steps:
and adjusting the network state-data packet mapping relation table according to the transmission delay corresponding to the transmitted split data.
The adjusting step may be performed based on the following steps:
firstly, if the transmission delay is smaller than a preset delay threshold, adjusting a network state-data packet mapping relation table to increase the length of a data packet for splitting data to be sent.
Secondly, if the transmission delay is larger than the preset delay threshold, the network state-data packet mapping relation table is adjusted to reduce the length of the data packet for splitting the data to be sent.
The preset time delay threshold is a preset time length for sending data to be sent from the beginning to the end of sending, and may be, for example, 5-30s, 1-3 minutes, and the like. The data packet length may be 1000 bytes, 1500 bytes, etc.
That is, when the duration of time for completing the transmission of the data to be transmitted from the beginning to the end of the transmission of the data is shorter than the duration set in advance, the packet length corresponding to the data to be transmitted in the network status-packet mapping relationship table can be appropriately increased.
When the time length used for sending the data to be sent from the beginning to the end of sending the data is longer than the preset time length, the data packet length corresponding to the data to be sent in the network state-data packet mapping relation table can be properly reduced.
In the transmission process, if the packet length is short but the transmission is still unsuccessful (the transmission delay is greater than the preset delay threshold), the packet length can be made to correspond to a larger network transmission rate for the same packet length in the network state-packet mapping table; if the length of the data packet is large and the data packet is successfully transmitted within a short time (the transmission delay is smaller than the preset delay threshold), the length of the data packet can be corresponding to a smaller network transmission rate for the same length of the data packet.
In these optional implementation manners, the correspondence between the network state parameter and the packet length corresponding to the split data may be optimized by continuously adjusting the network state-compression ratio mapping table, so as to obtain the length of the split data that is most matched with the current network state parameter.
Step S103, the system data transmission layer receives at least two split data sent by the preset data splitting component, and executes an operation of sending the at least two split data.
Generally, data transmission of an electronic device includes the following processes: first, the data to be transmitted needs to be split according to a fixed data size. Secondly, the split data is sent to an ip layer in batches. Third, it is then sent by the ip layer to the data link layer. Fourth, the data link layer transfers to the physical layer. Fifth, data is transmitted through a physical layer.
In some optional implementations, step S103 may include: and the system data transmission layer receives the at least two split data sent by the preset data splitting component and executes the operation of sending one split data of the at least two split data at the current moment.
That is, the system data transmission layer may send one split data at the current time, or may send multiple split data at the same time.
The system data transmission layer may perform an operation of transmitting one of the split data after receiving at least two split data transmitted by the preset data splitting component. For example, a piece of split data may be sent to the ip layer, and the ip layer is instructed to perform the operation of transferring the split data.
In this embodiment, the data splitting operation may mark a split identifier for each split data, where the split identifier of each split data is used to indicate the data to be sent corresponding to the split data and the sequence of the split data in each split data.
The split identifier can uniquely identify a certain split data. The split identifier may include letters, numbers, and/or other symbols.
When the data to be sent corresponding to the current moment is split according to the currently determined data packet length, the data to be sent is split into a plurality of split data, and each split data is marked with a split identifier, so that the split information of the split data as the split data and the sequence of the split data in the split data can be indicated.
In practice, in order to enable split data to be orderly assembled after being received by a data receiving client, each split data can be numbered in a data packet encapsulation stage and used as a field for describing a unique identifier of each split data. The number here is the above-mentioned splitting identifier.
For example, the data to be sent at the current time is "how good you are", when it is determined that the length of the data packet corresponding to the network state parameter at the current time is 1400 bytes, the data to be sent is split with the length of the data packet being 1400 bytes, and when the length of the data packet of the last split data is less than 1400 bytes, the data packet also independently becomes a split data.
When the length of the data packet corresponding to the current network state parameter does not exist in the network state-data packet mapping relation table, the data to be sent corresponding to the 'hello does' can be split into two split data with the same length, and then the split data is sent. And if the transmission fails within the preset data transmission time delay, further splitting each split data into two secondary split data with shorter data packet length. And by analogy, a bisection method is utilized until split data obtained by splitting data to be sent according to the method is successfully sent within a preset transmission time delay. And then, the length of the data packet corresponding to the successfully sent split data and the network state parameter at the current moment are stored in a network state-data packet mapping relation table in an associated mode.
After the preset data splitting component marks a splitting identifier on each split data, the system data transmission layer may receive the at least two split data sent by the preset data splitting component and the splitting identifier corresponding to each split data; then, the system data transmission layer may send the split data and the split identifier corresponding to the split data together.
The data packet is transmitted in the form of data frame in the course of sending, the above-mentioned data frame can be formed by "destination IP address", "source IP address", "net load data", etc., the structure of the data packet is very similar to the structure of the letter, the destination IP address is to explain to whom this data packet is sent, it is equivalent to addressee; the source IP address is used to indicate where the packet originated, and corresponds to the address of the sender; and the payload data corresponds to the content of the letter.
When each split data is sent to the target IP address from the source IP address, after the data receiving end of the target IP address receives all the split data, the payload data in all the split data is recombined according to the split identifier on each split data, and the received data consistent with the data to be sent is obtained.
In the prior art, generally, an unpacking scheme provided by a system data transmission layer of a terminal device (for example, a User Datagram Protocol (UDP)) is to split data to be transmitted according to a fixed length, and the unpacking length cannot be adjusted in real time according to a network state, so that split data obtained by splitting the data to be transmitted by the unpacking scheme provided by the system may not be all successfully transmitted to a destination, and then part of the data is lost, thereby causing information loss.
In order to solve the problem caused by unpacking data to be sent by an unpacking scheme provided by a system in the prior art, in this embodiment, a network state parameter at the current moment may be first obtained by an application program; then, the application program sends the network state parameters and the data to be sent at the current moment to the preset data splitting component, and the preset data splitting component executes the following data splitting operation: determining whether the network state parameter meets a preset network state parameter condition; in response to determining that the network state parameter does not meet the preset network state parameter condition, determining that the current network state is a weak network state; splitting data to be sent into at least two split data according to a splitting rule corresponding to the network state parameter; and finally, the system data transmission layer receives at least two split data sent by the preset data splitting component and executes the operation of sending the at least two split data. According to the technical scheme provided by the embodiment, the data to be transmitted can be split according to the current network state by using the data splitting component, the transmission success rate of the data to be transmitted in the weak network state is effectively improved, and the integrity of information is further improved.
