Background technique

During the data transmission process, business transparent transmission, as a service based on unreliable transmission, can be used in the management control system to manage terminal equipment.

When the network is congested, the transmitted data may be lost, causing the management control system to be unable to receive data from the terminal device in time, and the application program interface to be in a waiting state. At this time, the application can determine the timeout based on the second-level standard and retransmit after the timeout.

However, retransmitting data from the application of the management control system to the application of the terminal will cause a long time to obtain the terminal information, thereby causing a problem of poor user experience.

Moreover, every time the management control system manages terminal information, it needs to receive a terminal response or time out before sending the next request. When the amount of information obtained is relatively large, the time to obtain all information will be greatly increased.

Detailed ways

In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

Referring to Figure 1, there is shown a step flow chart of a service data transmission method provided by an embodiment of the present invention, which is applied to a first terminal. The first terminal includes an application layer, a data transmission layer and a data sending layer. The application layer is oriented to The user, in response to the user's input operation, selects a second terminal for business interaction with the first terminal, and determines the business data that needs to be transmitted to the second terminal. A sending interface can be set in the application layer, and the sending interface is used for incoming purposes. Data required in the business interaction process such as numbers, sub-numbers and business data; the data transmission layer is located between the application layer and the data transmission layer and is used to process data during the business transmission process. Reliable filling can be done in the data transmission layer Information required for transmission, such as: message sequence number, local window size, message type, cached data, number of transmissions, etc. The message sequence number can be the identifier of the data packet that the business data is split into, and the local window size is used to determine the data to be transmitted. The amount of data and message types can include response messages and request messages. Cache data can be used to temporarily store the business data being sent to avoid the need to re-obtain the data from the application layer after the business data is lost and shorten the reflection time. The data sending layer can be used to send business data to other external terminals. The first terminal and the second terminal may be terminals in the visual network. The first terminal and the second terminal can transmit through the service transparent transmission protocol,

Based on the first terminal in the embodiment of the present invention, the service data transmission process may specifically include the following steps:

Step 101: Create a retransmission mechanism and/or response mechanism in the data transmission layer during data transmission with the second terminal;

Among them, the retransmission mechanism can be a retransmission rule in the terminal that triggers the retransmission of service data or one or more data packets of the service data. One or more retransmission rules can be preset, and then when the first terminal is in the process of service , the interaction between terminals can be carried out based on this retransmission mechanism.

The response rule is to feed back corresponding response data to the terminal sending the data for the received data, so as to inform the terminal sending the data that the data has been received.

In an example, the retransmission mechanism and response mechanism can be created and generated by configuring corresponding fields in the data transmission layer.

In the embodiment of the present invention, a retransmission mechanism and/or a response mechanism are set at the data transmission layer. During the service data transmission process, the data transmission layer can perform retransmission and/or response, thereby increasing the reliability of the transmission, reducing the waiting time of the application layer, and improving the user experience in the case of network congestion.

Step 102: After the data transmission layer receives the service data to be transmitted to the second terminal, based on the data interaction between the data transmission layer and the data sending layer, a retransmission mechanism and/or a response mechanism is used to conduct business with the second terminal. Data transfer of data.

After the data transmission layer creates a retransmission mechanism and/or a response mechanism, when the data transmission layer receives the business data to be transmitted, it can determine whether the current business data transmission status is based on the created retransmission mechanism and/or response mechanism. In line with the preset trigger conditions of the retransmission mechanism and/or response mechanism, the data transmission layer and the data sending layer perform data interaction according to the retransmission mechanism and/or response mechanism to realize data transmission of business data.

For example, if it is detected that the current transmission of business data is in a transmission timeout state (for example, no response data corresponding to the business data is received within a preset time after sending the business data), the timeout retransmission mechanism can be started.

In one example, in the terminal, the service data is transmitted to another terminal along the direction of application layer - data transmission layer - data sending layer. The application layer can respond to the user's service data input operation and obtain the data to be sent to the second terminal. business data. Specifically, in the application layer, service data can be passed in through the sending interface of the calling terminal. In addition, in the application layer, a second terminal capable of transmitting service data can be selected from the address book, and the address information of the first terminal and the second terminal can be determined.

The business data of the application layer can be sent to the data transmission layer, and then, after being processed by the data transmission layer, is transmitted to the data transmission layer, where the business data is sent to the second terminal.

During the interaction process between the first terminal and the second terminal, the pre-created retransmission mechanism and/or response mechanism can be applied, that is, when the status of the first terminal and the second terminal meets the preset conditions in the retransmission mechanism or response mechanism , triggers the data transmission layer to retransmit data or respond.

In an embodiment of the present invention, the business data is cached in the data transmission layer; after the service data transmission is completed, the cached business data in the data transmission layer is cleared.

In the embodiment of the present invention, a retransmission mechanism and/or a response mechanism during data transmission with the second terminal are created in the data transmission layer; and then the service data to be transmitted to the second terminal can be received in the data transmission layer. , based on the data interaction between the data transmission layer and the data sending layer, the retransmission mechanism and/or response mechanism is used to transmit business data with the second terminal, realizing that during the data transmission process, retransmission and response are performed by the data The transport layer is triggered without reaching the application layer, thereby avoiding the application program to perform retransmissions. When the network is congested due to a large amount of data, the probability of successful data transmission can be improved. The application layer can learn in time whether the business data is sent to the second terminal. , Reduce application layer waiting time.

Referring to Figure 2, a flow chart of another method for transmitting service data provided by an embodiment of the present invention is shown. Specifically, it may include the following steps:

Step 201: Create a retransmission mechanism and/or response mechanism in the data transmission layer during data transmission with the second terminal; the retransmission mechanism is a timeout retransmission mechanism;

Step 202: When the data transmission layer sends service data to the second terminal, start the timer in the data transmission layer for timing;

The retransmission mechanism created in the data transmission layer may be a timeout retransmission mechanism, that is, when the first terminal does not receive response data beyond the preset time, the first terminal is triggered to resend the service data to the second terminal.

In the timeout retransmission mechanism, a timer can be set in the data transmission layer to record the data transmission time. When the business data can be sent to the data transmission layer through the data transmission layer, the data transmission layer can call the transmission interface and pass the business transparent transmission protocol Send business data. While sending business data, send instructions to data transmission to start the timer for timing.

Step 203: When the timing data of the timer is greater than or equal to the time threshold and the data transmission layer does not detect that the first terminal receives the response data for the service data feedback from the second terminal, the data transmission layer and the data transmission layer are used to transmit the service data. Retransmit to the second terminal.

In an example, the number of retransmissions can also be set in the timeout retransmission mechanism. For example, if the number of retransmissions is set to three times, the service data can be retransmitted three times to the second terminal when the timer is determined to have expired.

When the second terminal receives the service data sent at any time, it means that the retransmission is successful. When it does not receive it three times, it means that the retransmission fails. In the case of retransmission failure, the user can be prompted to confirm that the first terminal and the second terminal The device status of the terminal.

In the embodiment of the present invention, by setting a timeout retransmission mechanism, when the data transmission layer detects that the timer has expired, retransmission can be started from the data transmission layer. Compared with retransmission from the application layer, the response time can be shortened. , Reduce application layer waiting time.

Referring to Figure 3, a flow chart of another method for transmitting service data provided by an embodiment of the present invention is shown. Specifically, it may include the following steps:

Step 301: Create a retransmission mechanism and/or response mechanism in the data transmission layer during data transmission with the second terminal; the retransmission mechanism is a packet loss retransmission mechanism;

The service data is sent to the second terminal in the form of one or more data packets, and each data packet is set with a message sequence number.

The service data can be split into one or more data packets, and each data packet is numbered, that is, each data corresponds to its message sequence number, and then the data packet can be sent to the second terminal.

Step 302: Use the data transmission layer to receive the target message sequence number corresponding to the lost data packet sent by the second terminal;

Among them, the data transmission layer is used to execute the retransmission mechanism and/or response mechanism when the triggering conditions of the retransmission mechanism and/or response mechanism are met during the service data transmission process;

The second terminal receives the data packet, determines whether there is packet loss based on the message sequence number of the data packet, and then determines the target message sequence number corresponding to the lost data packet, and sends the target message sequence number to the first terminal, To trigger the first terminal to resend the data packet corresponding to the target message sequence number.

Step 303: Use the data transmission layer to retransmit the data packet corresponding to the target message sequence number to the second terminal.

The data transmission layer is used for data interaction with the data transmission layer of the first terminal and/or the second terminal during service data transmission. Specifically, the data sending layer in the first terminal sends data from the first terminal to the second terminal or receives data sent from the second terminal to the first terminal.

In an embodiment of the present invention, after triggering retransmission, the number of retransmissions is determined; when the number of retransmissions is greater than the preset number, retransmissions are stopped.

In an embodiment of the present invention, the business data is cached in the data transmission layer; after the service data transmission is completed, the cached business data in the data transmission layer is cleared.

In the embodiment of the present invention, the first terminal can retransmit the data packets lost during the data transmission process, thereby ensuring that the second terminal can receive all data packets of the service data. When the network is congested due to a large amount of data, the probability of successful data transmission can be increased. The application layer can learn in time whether the business data is sent to the second terminal, reducing the waiting time of the application layer.

Referring to Figure 4, a flowchart of steps of another service data transmission method provided by an embodiment of the present invention is shown. Specifically, it may include the following steps:

Step 401: Create a retransmission mechanism and/or response mechanism in the data transmission layer during data transmission with the second terminal;

Step 402: Use the data transmission layer and the data sending layer to send the service data to the second terminal;

Step 403: Use the data sending layer to receive response data returned by the second terminal for the service data.

After the first terminal sends the service data to the second terminal, the response data fed back by the second terminal can be received based on the response mechanism.

The response data of the second terminal may include but is not limited to: a response message indicating that the service data is successfully sent, and a message indicating that the service data is failed to be sent.

In the embodiment of the present invention, the device response mechanism between the first terminal and the second terminal is transmitted based on the response mechanism, which can improve the probability of successful data transmission, and the application layer can learn in time whether the service data is sent to the second terminal, reducing Application layer waiting time.

Referring to FIG. 5 , there is shown a step flow chart of another service data transmission method provided by an embodiment of the present invention, which is applied to a second terminal. The second terminal includes an application layer, a data transmission layer, and a data sending layer.

Based on the second terminal in the embodiment of the present invention, the service data transmission process may specifically include the following steps:

Step 501: Create a retransmission mechanism and/or response mechanism in the data transmission layer during data transmission with the first terminal;

Step 502: Use the data sending layer to receive the service data sent from the first terminal to the second terminal;

Step 503: Based on the data interaction between the data transmission layer and the data sending layer, a retransmission mechanism and/or a response mechanism is used to transmit service data with the first terminal.

In one embodiment of the present invention, the retransmission mechanism is a packet loss retransmission mechanism. The service data is sent to the second terminal in the form of one or more data packets. Each data packet is set with a message sequence number, and a data transmission layer is used. and the data transmission layer, based on the retransmission mechanism and/or response mechanism, to perform data transmission of business data with the first terminal, including: using the data transmission layer to determine the transmission of service data from the first terminal to the second terminal based on the message sequence number of the received data packet. Whether there is packet loss during the process of sending data packets; when the data transmission layer determines that there is packet loss in business data transmission, it determines that the lost data packet corresponds to the target message sequence number; sends the target message sequence number to the first terminal so that the first The terminal retransmits the data packet corresponding to the target message sequence number to the second terminal.

In an example, when the data transmission layer receives the service data, it determines whether it is a response message based on the service data type. When the service data is not a response message, it determines whether it is received based on the message sequence number of each received data packet. When all data packets are received, multiple data packets can be reorganized according to the message sequence number, the business data can be restored, and the business data can be fed back to the application layer.

When not all data packets are received, that is, packet loss occurs during the service data transmission process between the first terminal and the second terminal, a feedback message can be sent to the first terminal, and the feedback message can first carry the lost packet. The data packet corresponds to the target message sequence number, and the data packet retransmission can be triggered by the target message sequence number.

In an example, when not all data packets are received, it is determined whether the reception times out. If the reception times out, the data continues to be received. If the reception times out, the first terminal may send a feedback message.

In the embodiment of the present invention, a retransmission mechanism and/or a response mechanism during data transmission with the first terminal is created in the data transmission layer; the data transmission layer is used to receive the data sent by the first terminal to the second terminal. The service data of the terminal; based on the data transmission layer and the data sending layer, the retransmission mechanism and/or the response mechanism are used to perform data transmission of the service data with the first terminal. It realizes that during the data transmission process, retransmission and response are triggered by the data transmission layer without reaching the application layer, thus avoiding the application program to perform retransmission. When the network is congested due to a large amount of data, it can increase the probability of successful data transmission. , the application layer can learn in time whether the business data is sent to the second terminal, reducing the waiting time of the application layer.

As shown in Figure 6a, it is a schematic diagram of a data interaction process for reliable transmission through a service transparent transmission protocol in an embodiment of the present invention.

The first terminal may include management and control software (i.e., application layer), a reliable transmission module (i.e., data transmission layer and data transmission layer), and the second terminal may include a reliable transmission module (i.e., data transmission layer and data transmission layer) and a terminal application. Program (i.e. application layer),

The interaction between the first terminal and the second terminal may include but is not limited to the following three types:

Category 1: The management and control software of the first terminal sends data to the reliable transmission module. The reliable transmission module sends the business transparent transmission message to the reliable transmission module of the second terminal based on the business transparent transmission protocol. The reliable transmission module of the second terminal transmits the data Uploaded to the terminal application of the second terminal, and at the same time, the ACK message is fed back to the reliable transport layer of the first terminal.

Category 2: The management and control software of the first terminal sends data to the reliable transmission module. The reliable transmission module sends business transparent transmission messages based on the business transparent transmission protocol. If the first terminal times out and does not receive the ACK message, that is, the response times out, it retransmits. If the transparent transmission message of this service times out after three retransmissions, the data transmission failure will be reported to the management and control software of the first terminal and retransmission will be stopped.

Category 3: The management and control software of the first terminal sends data to the reliable transmission module. The reliable transmission module sends business transparent transmission messages based on the business transparent transmission protocol. The business transparent transmission messages are divided into 4 data packets for transmission respectively. When the second When the terminal's reliable transmission module does not receive the service transparent transmission message (3/4), it can send an ACK to the reliable transmission module of the first terminal (the third message is lost). After receiving the pending ACK, the first terminal re- Transmit the business transparent transmission message (3/4) to the reliable transmission module of the second terminal. After the reliable transmission module of the second terminal receives it, it can send all the business transparent transmission messages to the application program and send them to the first terminal. The terminal's reliable transmission module sends ACK. The reliable transmission module of the first terminal sends a successful message to the management and control software.

As shown in Figure 6b, it is a schematic diagram of a service data transmission process in an embodiment of the present invention.

In the application layer of the first terminal: call the sending interface, input the destination number, sub-number and data to be sent (ie, service data).

In the reliable transmission layer (that is, the data transmission layer) of the first terminal, information required for reliable transmission can be filled in, such as message sequence number, local window size, message type, cached data, transmission number settings, etc.

After the basic data configuration is completed, the configured data can be sent to the business transparent transmission layer (that is, the data transmission layer).

In the service transparent transmission layer, the sending interface can be called to send service data to the service transparent transmission layer of the second terminal through the service transparent transmission protocol. At the same time, the service transparent transmission layer of the first terminal can send data to the first terminal when sending data. The reliable transport layer of the first terminal sends a message to start the timer in the reliable transport layer of the first terminal. When the reliable transport layer detects that the timer has expired, it triggers the retransmission of the service data. During the retransmission process, it determines the current retransmission. Whether the number of retransmissions is greater than three times. When the number of retransmissions is greater than three times, the application is notified that the service data transmission failed this time. When the number of retransmissions is less than three times, retransmissions can continue until the second terminal is received within the preset time. ACK.

When service data is transmitted from the service transparent transmission layer of the first terminal to the service transparent transmission layer of the second terminal. Then the received data can be sent to the reliable transport layer for processing.

In the reliable transport layer of the second terminal, it is judged whether the received data is a response message. When the received data is a response message, the timer of the reliable transport layer is stopped and it is judged whether the response message is correct. When the response is correct, it is necessary to determine whether there is response content. If there is response content, extract the user data and return it to the application program of the first terminal. When there is no response content, notify the first terminal application program that the transmission was successful.

In the case of receiving data non-response messages, it can be determined whether all messages have been received. When all messages are received, all messages can be reorganized and the reorganized data can be returned to the application program of the second terminal; when When not all messages are received, it is determined whether the current reception has timed out. If the reception has not timed out, continue to receive data. When the reception times out, an ack message (including the sequence number of the lost message) is sent to the first terminal. reliable transport layer.

In the case of a response error, it can be determined whether the number of times the current service data has been sent is less than three times. If it is less than three times, the application program of the first terminal is notified of the sending failure and continues to retransmit. If it is greater than or equal to three times, retransmission will be stopped.
