The present disclosure relates to the technical field of data transmission, and in particular, to a data transmission method, apparatus, electronic device, and computer readable storage medium.
Background
In industries needing large-flow data transmission, such as stock and securities industries, the data amount is greatly changed, and when the data amount is changed, the data needs to be transmitted to a client for display, so that more scenes needing large-flow data transmission exist, such as scenes of implementing disc opening, thousand-file data and the like. And because the data volume changes faster, the data issued by the server has the characteristics of higher frequency, larger data volume and small fluctuation of adjacent data changes in the issued data.
The change of the data volume can be used for guiding the subsequent selection and operation of a user in the securities industry, so that the accurate data delivery is very heavy, and meanwhile, the consumption of the flow is also required to be reduced because the data volume delivered is also large, so that the technical problem of how to deliver the data under the conditions of ensuring the accuracy and reducing the flow consumption is urgently solved.

Detailed Description
Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.
Data transmission methods, apparatuses, electronic devices, and computer-readable storage media of the embodiments of the present disclosure are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a data transmission method according to an embodiment of the disclosure. In the present disclosure, the inventor finds that in the field of video coding, a GOP (video compression technology used by MPEG) has a good compression effect, so that transmission efficiency can be improved, and the GOP can completely play video content without concern about its context.
In the present disclosure, a standard GOP is set to include a full-size data frame I and a difference data frame P, where the full-size data frame includes complete data, and the difference data frame includes a difference between data sent this time and data of the full-size data frame sent last time.
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 present disclosure may be performed by the data transmission device of the embodiment of the present disclosure, and the data transmission device of the embodiment of the present disclosure may be configured in any server to perform the data transmission method of the embodiment of the present disclosure, where the server may be a local server or a server disposed in a cloud.
The client refers to an application program, a web page, a terminal device, or the like which is served by the server.
Wherein the frame interval is used to indicate the last time a full data frame was transmitted to the total number of frames that have been currently transmitted. The set frame number is a preset frame number indicating the frame number included between two transmission of the full-size data frame. That is, it is set in the present disclosure that the full data frame is transmitted every set number of frames. For example, if the number of frames is 10, a full-frame data frame is transmitted every 10 frames.
In the present disclosure, the number of frames that have been transmitted for the last transmission of the full-size data frame is compared with the set number of frames according to the distance indicated by the frame interval to determine whether the set number of frames is met.
For example, the frame number is set to be 10 frames, the full-quantity data frames are sent by 0 frames, and if the frame interval between the frame to be sent currently and the frame which is sent the full-quantity data frames to the client last time is determined to be 7 frames, the frame interval 7 frames do not accord with the set frame number of 10 frames; if the frame interval between the frame to be transmitted and the frame which transmits the full data frame to the client last time is 10 frames, the frame interval 10 frames accords with the set frame number 10 frames.
In this embodiment, when the frame interval accords with the set frame number, the full-volume data frame with larger data volume is sent to the client, and compared with the mode of only sending the full-volume data frame in the prior art, the flow data consumed by the client when receiving the data frame is reduced, so that the flow of the client is controllable.
In this embodiment, if it is determined that the sent frame number indicated by the frame interval meets the set frame number, the requirement of sending the full-size data frame to the client based on the set frame number is met, the full-size data frame is sent to the client, if the requirement of sending the full-size data frame to the client based on the set frame number is not met, the full-size data frame or the difference data frame can be determined to be sent to the client according to the time interval of sending the full-size data frame to the client last time, so as to meet the accuracy requirement of data sending, meanwhile, the flow consumption of the client is considered, and compared with the prior art, the accuracy of displaying data by the client is improved by only sending the difference data frame.
In a possible implementation manner of the embodiment of the present disclosure, it is determined that the frame interval does not conform to the set frame number, and according to a time interval of last sending of a full-size data frame to the client, if the time interval is greater than or equal to a threshold duration, it is determined that the full-size data frame is sent to the client, and if the time interval is less than the threshold duration, it is determined that the difference data frame is sent to the client, so that when the frame interval does not conform to the set frame number, it is determined whether to send the full-size data frame or the difference data frame according to the time interval, so as to meet a requirement of data frame sending, and improve accuracy of data sending.
In the data transmission method of this embodiment, it is determined whether the frame interval of the full-size data frame that was last transmitted to the client matches the set frame number, if the frame interval matches the set frame number, it is determined to transmit the full-size data frame to the client, and if the frame interval does not match the set frame number, it is determined to transmit the full-size data frame or the difference data frame to the client according to the time interval of the full-size data frame that was last transmitted to the client. In this embodiment, based on the set frame number and the sending time interval, the sending of the full-volume data frame or the difference data frame is determined, and because the difference data frame is the difference data sent for each client, the data volume is smaller, so that the client flow is controllable, and because the full-volume data frame contains comprehensive data, no data loss exists, and therefore the accuracy of issuing data is also satisfied.
Based on the above embodiment, the present embodiment provides another data transmission method, taking a securities application scenario among application scenarios issued by large-flow data as an example, and fig. 2 is a flow chart of another data transmission method provided by the embodiment of the present disclosure.
As shown in fig. 2, the method comprises the steps of:
The execution subject of the present disclosure is a server, where the server is a server of a security application, and the client is all applications of the security installed in a terminal device of a user, or may be a web page, an application program, or the like used by a manager or a developer of the security application to manage and maintain the security application, which is not limited in the embodiments of the present disclosure.
In this embodiment, after a connection is established between the server and the client, the round value corresponding to the client is set to 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 round value is dynamically changed, and when the server transmits the data frames to the client, the round value corresponding to the client is added with 1, so that the round value is used for indicating the total frame number of the data frames sent to the client, and the data frames comprise full data frames and difference data frames.
In step 203, if the round value is an integer multiple of the set frame number, it is determined that the frame interval matches the set frame number.
In the embodiment of the disclosure, according to the obtained round value, it is determined whether the round value is an integer multiple of the set frame number, if the round value is the integer multiple, it is determined that the frame interval accords with the set frame number, that is, the frame which has been transmitted currently accords with the set frame number relative to the frame which has been transmitted last time to the client, and the full-size data frame can be transmitted to the client.
For example, the number of frames is set to 10 frames, that is, a full-frame data frame is transmitted every 10 frames, the acquired round value is 30 frames, the round value is 30 frames which are 3 times as large as the set number of frames 10 frames, and the frame interval between the frame to be currently transmitted and the full-frame data frame to be transmitted last is determined to be 10 frames, and the 10 frames are consistent with the set number of frames 10 frames, so that it is determined that the full-frame data frame can be transmitted again to the client.
In a possible implementation manner of the embodiment of the present disclosure, before the full-size data frame is sent to the client, the full-size data frame to be sent may be obtained from the first interface, that is, the full-size data frame is obtained through a dedicated first interface, and by setting an independent first interface at the server, the full-size data frame is obtained through the first interface, so that protocol analysis is not required, and the full-size data frame can be directly sent to the corresponding client after being obtained, thereby reducing the delay of data sending.
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, the obtained round value is 36 frames, the 36 frames are not integer multiples of the set frame number 10 frames, the frame interval is determined to be 6, the set frame number 10 frames are not met, whether the full-size data frames can be transmitted or not is determined according to the frame interval, further, in order to improve the accuracy of the frames to be transmitted, the time interval for transmitting the full-size data frames can be set, whether the full-size data frames are transmitted or the difference data frames are transmitted is determined according to the time interval, and the accuracy of data transmission is improved.
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-size data frame is satisfied according to the time interval for retransmitting the full-size data frame to the client, and when the time interval for retransmitting the full-size data frame is not satisfied, the transmission of the difference data frame is performed, so as to improve the accuracy of the data displayed to the client, and reduce the traffic consumption of the client.
In this embodiment, when it is determined that the difference data frame is sent to the client, so that when the total data frame is not sent again, the difference data frame is sent, so as to reduce the flow requirement of the client, and ensure the accuracy of the display data of the client.
In another embodiment of the present disclosure, before sending the difference data frame to the client, the difference data frame to be sent may be obtained from the second interface, that is, the difference data frame is obtained through a dedicated second interface, and by setting an independent second interface at the server, the difference data frame is obtained through the second interface, so that protocol analysis is not required, and the difference data frame can be directly sent to the corresponding client after being obtained, thereby reducing the delay of data sending.
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, it may be queried 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, and conversely, if the query determines that the round value corresponding to the client is an initial value, it may be determined that the server and the client have not performed service data communication, and cannot send the difference data frame to the client, and discard the obtained difference data frame and do not send the difference data frame to the corresponding client.
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 a difference data frame which is different from the last transmitted full-size data frame.
For example, there are 5000 stocks, the total data frame is all data of 5000 stocks, and the difference data frame indicates that only 200 stocks are updated compared with the 5000 stocks transmitted last time, so the difference data frame transmitted this time is the data of 200 stocks updated with data, and the data of 4800 stocks not updated is not transmitted.
Wherein the data of each stock may contain the following fields:
head: a header field holding some meta information, wherein frame_type is key parameter information for representing a frame type;
op_code: an operation code;
code: a security code;
buy_value: total commission purchase amount;
sel_value: total commission sales;
but_volume: total commission purchase amount;
sel_volume: total commission sales;
detail: list of specific structures, detailed information.
The specific structure list may include the following fields:
price: price of securities;
volume: stock exchange;
level: a transaction gear;
and (3) flag: a transaction direction;
major_volume: stock order consignment;
and the order list is the detailed order information.
And step 208, updating the round value corresponding to the client.
In this embodiment, the round value is used to indicate the total frame number of the data frames sent to the client, where the data frames include a full data frame and a difference data frame, so that after the difference 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, the round value corresponding to the client may be added by 1 in an accumulated manner to update.
In the data transmission method of this embodiment, it is determined whether the frame interval of the full-size data frame that was last transmitted to the client matches the set frame number, if the frame interval matches the set frame number, it is determined to transmit the full-size data frame to the client, and if the frame interval does not match the set frame number, it is determined to transmit the full-size data frame or the difference data frame to the client according to the time interval of the full-size data frame that was last transmitted to the client. In this embodiment, based on the set frame number and the sending time interval, the sending of the full-volume data frame or the difference data frame is determined, and because the difference data frame is the difference data sent for each client, the data volume is smaller, so that the client flow is controllable, and because the full-volume data frame contains comprehensive data, no data loss exists, and therefore the accuracy of issuing data is also satisfied.
In order to implement the above embodiment, the present disclosure further proposes a data transmission device.
