Detailed Description
Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.
A data transmission method, an apparatus, an electronic device, and a computer-readable storage medium of the embodiments of the present disclosure are described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a data transmission method according to an embodiment of the present disclosure. In the present disclosure, the inventor finds that in the field of video coding, a GOP (a video compression technology used by MPEG) has a good compression effect, and can improve transmission efficiency, and the GOP can completely play video content without concerning the context thereof.
In this disclosure, a standard GOP is set to include a full data frame I and a difference data frame P, where the full data frame includes complete data, and the difference data frame includes a difference between data of this time of transmission and data of a last time of transmission of the full data frame.
As shown in fig. 1, the method comprises the steps of:
The execution subject of the data transmission method of the present disclosure is a server. The data transmission method of the embodiment of the disclosure can be executed by the data transmission device of the embodiment of the disclosure, and the data transmission device of the embodiment of the disclosure can be configured in any server to execute the data transmission method of the embodiment of the disclosure, wherein the server can be a local server or a server arranged at a cloud.
The client refers to an application, a web page, a terminal device, or the like that is served by the server.
Wherein the frame interval is used to indicate the total number of frames that have been transmitted from the last time the full data frame was transmitted to the current frame. The set frame number is a predetermined number indicating the number of frames included between two transmissions of the full data frame. That is, the present disclosure sets that the full data frame is transmitted once every set number of frames. For example, if the number of frames is set to 10, a full data frame is transmitted every 10 frames.
In the present disclosure, the number of frames that have been transmitted according to the frame interval indication from the last transmission of the full data frame is compared with the set number of frames to determine whether the set number of frames is met.
For example, setting the frame number to be 10 frames, sending a full data frame by 0 frame, and if determining that the frame interval between the current frame to be sent and the frame for sending the full data frame to the client at the latest time is 7 frames, the frame interval of 7 frames does not conform to the setting frame number of 10 frames; if the frame interval between the current frame to be sent and the frame for sending the full data frame to the client for the last time is determined to be 10 frames, the frame interval of 10 frames accords with the set frame number of 10 frames.
And 102, if the frame interval accords with the set frame number, determining to send the full data frame to the client.
In this embodiment, when the frame interval meets the set frame number, the full data frame with a large data volume is sent to the client, and compared with the prior art in which only the full data frame is sent, the method reduces the traffic data consumed when the client receives the data frame, so that the traffic of the client is controllable.
And 103, if the frame interval does not accord with the set frame number, determining to send the full data frame or the difference data frame to the client according to the time interval of sending the full data frame to the client at the last time.
In this embodiment, if it is determined that the sent frame number indicated by the frame interval meets the set frame number, the requirement for sending the full data frame to the client again based on the set frame number is met, the full data frame is sent to the client, and if the requirement for sending the full data frame to the client again based on the set frame number is not met, the full data frame or the differential data frame may be determined to be sent to the client according to the time interval of sending the full data frame to the client for the last time, so as to meet the accuracy requirement of data sending, and meanwhile, the traffic consumption of the client is considered.
In a possible implementation manner of the embodiment of the present disclosure, it is determined that a frame interval does not conform to a set frame number, and according to a time interval of sending a full data frame to a client for the last time, if the time interval is greater than or equal to a threshold duration, it is determined to send the full data frame to the client, and if the time interval is less than the threshold duration, it is determined to send a difference data frame to the client, so that when the frame interval does not conform to the set frame number, it may be determined whether to send the full data frame or send the difference data frame according to the time interval, so as to meet a requirement of sending the data frame, and improve accuracy of sending the data.
In the data transmission method of this embodiment, it is determined whether a frame interval at which a full data frame is last sent to the client meets a set frame number, if the frame interval meets the set frame number, it is determined to send the full data frame to the client, and if the frame interval does not meet the set frame number, it is determined to send the full data frame or a difference data frame to the client according to a time interval at which the full data frame is last sent to the client. In this embodiment, the sending of the full data frame or the differential data frame is determined based on the set frame number and the sending time interval, the traffic of the client is controllable because the differential data frame is the differential data sent by each client, and the accuracy of data sending is also satisfied because the full data frame contains comprehensive data and there is no data loss.
Based on the previous embodiment, this embodiment provides another data transmission method, which is described by taking a security application scenario in an application scenario in which large-flow data is issued as an example, and fig. 2 is a schematic flow chart of another data transmission method provided in this embodiment of the present disclosure.
As shown in fig. 2, the method comprises the following steps:
The execution subject of the present disclosure is a server, the server is a server of a certain security application, and the client is all the security applications installed in the terminal device of the user, and may also be a web page, an application, and the like used by a manager and a developer of the security applications to manage and maintain the security applications, which is not limited in the embodiment of the present disclosure.
In this embodiment, after the connection is established between the server and the client, the round value corresponding to the client is set as an initial value to indicate that no service data communication has been performed between the client and the server, that is, the server has not sent any data frame to the client.
The turn value is dynamically changed, and each time the server issues a data frame to the client, the turn value corresponding to the client is added with 1, so that the turn value is used for indicating the total number of data frames sent to the client, and the data frames comprise full data frames and difference data frames.
And step 204, determining to send the full data frame to the client, and sending the full data frame to the client.
In the embodiment of the present disclosure, according to the obtained round value, it is determined whether the round value is an integer multiple of the set frame number, and if the round value is the integer multiple, it is determined that the frame interval corresponds to the set frame number, that is, the frame that has been currently sent corresponds to the set frame number with respect to the last sending of the full data frame to the client, and the full data frame can be sent to the client.
For example, the set frame number is 10 frames, that is, a full data frame is sent every 10 frames, the obtained round value is 30 frames, the round value of 30 frames is 3 times of the set frame number of 10 frames, and is an integer multiple, the frame interval between the current frame to be sent and the most recently sent full data frame is determined to be 10 frames, and 10 frames are consistent with the set frame number of 10 frames, so it is determined that the full data frame can be sent to the client again.
In a possible implementation manner of the embodiment of the present disclosure, before sending the full data frame to the client, the full data frame to be sent may also be obtained from the first interface, that is, the full data frame is obtained through the dedicated first interface, and by setting the independent first interface at the server and obtaining the full data frame through the first interface, protocol analysis may not be required, and the full data frame may be directly sent to the corresponding client after being obtained, so that a time delay of data sending is reduced.
In step 205, if the round value is not an integer multiple of the set frame number, it is determined that the frame interval does not conform to the set frame number.
For example, if the obtained round value is 36 frames, and the 36 frames are not integer multiples of 10 frames of the set frame number, it is determined that the frame interval is 6, the frame interval is not 10 frames of the set frame number, and it is not determined whether the full data frame can be sent according to the frame interval.
In this embodiment, when it is determined that the frame interval does not meet the set frame number, it is further determined whether the time interval for retransmitting the full data frame is satisfied according to the time interval for transmitting the full data frame to the client for the last time, so as to ensure the transmission of the full data frame, and when the time interval for retransmitting the full data frame is not satisfied, the differential data frame is transmitted, so as to improve the accuracy of data transmitted to the client for display, and reduce the traffic consumption of the client.
In the embodiment, the difference data frame is sent to the client when the difference data frame is determined to be sent to the client, so that the difference data frame is sent when the full data frame is not sent again, the flow requirement of the client is reduced, and the accuracy of data display of the client is ensured.
In another embodiment of the present disclosure, before the differential data frame is sent to the client, the differential data frame to be sent may also be obtained from the second interface, that is, the differential data frame performs data acquisition through the dedicated second interface, and by setting the independent second interface at the server and using the second interface to perform differential data frame acquisition, it may be implemented that no protocol analysis is required, and the differential data frame may be directly sent to the corresponding client after being obtained, so as to reduce the time delay of data sending.
It should be noted that the first interface and the second interface are independent interfaces.
In another embodiment of the present disclosure, before sending the difference data frame to the client, a query may be performed to determine that the round value corresponding to the client is not an initial value, that is, when the round value corresponding to the client is not an initial value, it may be determined that the server and the client have performed service data communication, and the difference data frame may be sent to the client.
It should be noted that, when the full-size data frame and the difference data frame in the video are applied to the stock industry, the full-size data frame represents all stock data, and the difference data frame represents the difference data frame that is different from the full-size data frame that was transmitted last time.
For example, there are 5000 stocks, and the full data frame is all data of 5000 stocks, while the difference data frame indicates that only 200 stocks are updated compared with 5000 stocks sent recently, so the difference data frame sent this time is data of 200 stocks with updated data, and data of 4800 stocks not updated is not sent.
The data for each stock may include the following fields:
a header: a header field holding some meta information, where frame _ type is key parameter information for indicating a frame type;
op _ code: an operation code;
code: a security code;
buy _ value: total committed bid amount;
sel _ value: total commission sales;
buy _ volume: total committed bid amount;
self _ volume: total committed sales volume;
detail: specific structure list and detailed information.
The specific structure list may include the following fields:
price: the price of the security;
volume: the amount of securities traded;
level: a transaction gear;
flag: the direction of the transaction;
major _ volume: the volume of orders for securities;
orders, delegation lists, detailed delegation information.
And step 208, updating the corresponding round value of the client.
In this embodiment, the round value is used to indicate a total number of data frames sent to the client, where the data frames include a full data frame and a differential data frame, so that after the differential data frame or the full data frame is sent to the client, the round value corresponding to the client needs to be updated, and optionally, 1 may be added to the round value corresponding to the client in an accumulated manner to perform the update.
In the data transmission method of this embodiment, it is determined whether a frame interval at which a full data frame is last sent to the client meets a set frame number, if the frame interval meets the set frame number, it is determined to send the full data frame to the client, and if the frame interval does not meet the set frame number, it is determined to send the full data frame or a difference data frame to the client according to a time interval at which the full data frame is last sent to the client. In this embodiment, the sending of the full data frame or the differential data frame is determined based on the set frame number and the sending time interval, the traffic of the client is controllable because the differential data frame is the differential data sent by each client, and the accuracy of data sending is also satisfied because the full data frame contains comprehensive data and there is no data loss.
