technical field

The present invention relates to the communication field, in particular to a method and device for optimizing bandwidth usage.

Background technique

Desktop cloud is a remote desktop application based on cloud computing technology. Through the desktop cloud platform, it can provide clients or any other devices that can connect to the network with virtualized "computers" or push application desktops, that is to say, clients or other Any device that can be connected to the network can access the personal desktop and various applications on the server side through a dedicated program or browser, and the user experience is the same as using a traditional personal computer.

In desktop cloud applications, the server needs to transmit graphics data and audio and video data to the client through the network. In order to save bandwidth, the server usually compresses these data in a certain way before transmitting it to the client. Under normal circumstances, the desktop of the server is usually compressed into pictures or video streams, the system sound of the server is compressed into audio streams of a certain format, and the media files played on the server are first separated into audio and video, and then the audio and video are separated separately. Transcoding compressed or not compressed, sent directly to the client. Different applications often have different requirements for data transmission. For example, an application that plays a slide show needs to transmit a large amount of graphics data, while an application that plays audio and video needs to transmit a large amount of audio and video data. Because in some application scenarios of the desktop cloud, these applications may need to run at the same time, so these different types of data must be transmitted at the same time and share bandwidth. In the prior art, the server uses fixed compression parameters to compress graphic data, and does not control the transmission rate of graphic data and audio and video data, and always transmits data at a fixed rate.

There are at least the following problems in the prior art: since the server uses fixed compression parameters to process data, it is impossible to dynamically control the data volume of graphics data, and since there is no control over the transmission rate of graphics data and audio and video data, the bandwidth of transmission data The usage depends on the bit rate of graphics data and audio and video data, and when the bit rate of graphics data and audio and video data exceeds the network bandwidth, neither the graphics application nor the media application of the client can obtain enough data in time, resulting in Refresh is slow, graphics lag, and even "scrolling" phenomenon occurs, which will cause the media application to freeze and audio and video are not synchronized, seriously affecting the user experience.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

An embodiment of the present invention provides a bandwidth usage optimization method, as shown in Figure 1, in the desktop cloud system, the client application needs to obtain the data it needs from the server through the network, in the case of insufficient bandwidth, in order to make the client Graphics applications and media applications on the client side can obtain enough data from the server side in time to allow users to obtain a good experience. Embodiments of the present invention provide a solution, which may include:

101. Obtaining data processing delay.

Among them, the client can obtain the processing delay of processing the current data. For example, if the application currently running on the client is a graphics application, then the client can collect the rendering delay of the graphics data. If the application running on the client is a media application, then the client The playback delay of audio and video data can be collected.

102. Determine the relationship between the delay and a preset delay threshold, where the delay threshold includes a first delay threshold.

Wherein, after the client obtains the time delay for processing the current data, it can judge the relationship between the time delay and the preset time delay threshold, and the specific value of the time delay threshold can be obtained according to the bandwidth of the network.

103. When the time delay is greater than the first time delay threshold, send to the server a first flow control request for requesting the server to reduce the transmission code rate, so that the server reduces the transmission code rate according to the first flow control request, so that the client can obtain enough data in time.

Among them, in the desktop cloud system, the server uses fixed compression parameters to process data, so it is impossible to dynamically control the data volume of graphics data, and there is no control mechanism for the transmission rate of graphics data and audio and video data. The bandwidth usage of data transmitted by the client depends on the transmission bit rate of graphics data and audio and video data. When the client judges that the delay is greater than the preset first delay threshold, that is to say, when the delay is too large, it indicates that the bandwidth is insufficient. At this time, the client can send the first stream to the server to request the server to reduce the transmission bit rate Control request, when the server receives the first flow control request sent by the client, it can reduce the data transmission bit rate according to the first flow control request, so that at the cost of a certain graphics image quality, the amount of data can be reduced to improve the performance of graphics applications. Refresh speed and playback fluency of media applications, so as to ensure that in the case of insufficient bandwidth, the client can still obtain enough data in time to ensure user experience. Wherein, lowering the data transmission bit rate specifically may be lowering the graphic data transmission bit rate, lowering the audio/video data transmission bit rate, or lowering the graphic data and audio/video data transmission bit rate simultaneously.

The bandwidth usage optimization method provided by the embodiment of the present invention obtains the current network bandwidth usage by judging the relationship between the acquired data processing delay and the preset delay threshold, and when the delay is judged to be greater than the first Extend the threshold, that is, when the network bandwidth is insufficient, send the first flow control request to the server to request the server to reduce the transmission code rate, so that the server can reduce the transmission code rate according to the first flow control request, so that the client can obtain enough data in time, so that In the case of insufficient network bandwidth, graphics applications and media applications on the client side can obtain sufficient data in a timely manner, which improves user experience.

Another embodiment of the present invention provides a bandwidth usage optimization method, as shown in Figure 2, the method may include:

201. Obtain data processing delay.

202. Determine the relationship between the time delay and the preset time delay threshold. When the time delay is greater than the first time delay threshold, perform the following step 203; when the time delay is less than the second time delay threshold, perform the following step 204.

Among them, the client can set the first delay threshold and the second delay threshold in advance according to the bandwidth of the network, wherein the first delay threshold is used to judge whether the current bandwidth is insufficient, and the second delay threshold is used to judge the current bandwidth Whether there is a balance, the first delay threshold is greater than the second delay threshold.

203. Send to the server a first flow control request for requesting the server to reduce the transmission code rate, so that the server reduces the transmission code rate according to the first flow control request, so that the client obtains enough data in time.

204. Send a second flow control request for requesting the server to increase the transmission code rate to the server, so that the server increases the transmission code rate according to the second flow control request.

Wherein, when the client judges that the delay is less than the second threshold, that is to say, when the current bandwidth is sufficient, the client can send the second flow control request to the server to request the server to increase the transmission code rate. When the server receives When the second flow control request is made, the data transmission rate can be increased according to the second flow control request, so as to make full use of the bandwidth provided by the network. Wherein, increasing the transmission code rate of data may specifically increase the transmission code rate of graphics data, may also increase the transmission code rate of audio and video data, and may also increase the transmission code rate of graphics data and audio and video data at the same time.

It should be noted that, for the specific description of steps 201 to 204 in the bandwidth usage optimization method provided by the embodiment of the present invention, you can refer to the specific description of the corresponding steps in steps 101 to 103 in another embodiment of the present invention. I will not repeat them one by one.

The bandwidth usage optimization method provided by the embodiments of the present invention obtains the current network bandwidth usage by judging the relationship between the acquired data processing delay and the preset delay threshold, and determines that the delay is greater than the first Delay threshold, that is, when the network bandwidth is insufficient, send the first flow control request to the server to request the server to reduce the transmission code rate, so that the server can reduce the transmission code rate according to the first flow control request, so that the client can obtain enough data in time, In the case of insufficient network bandwidth, graphics applications and media applications of the client can obtain sufficient data in time, thereby improving user experience.

In addition, two delay thresholds can be set on the client, and when the client judges that the delay is less than the second delay threshold, a second flow control request for increasing the transmission code rate is sent to the server, so that the server can increase the transmission code rate. rate, so that the network bandwidth can be fully utilized.

Another embodiment of the present invention provides a method for optimizing bandwidth usage. Because in the case of insufficient bandwidth, the server is at the expense of the quality of graphics and images, and by reducing the amount of data, it is ensured that the picture application and media application of the client can obtain enough bandwidth in time. Data, to ensure the user's viewing experience, in the embodiment of the present invention, the user can set different working modes on the client, the working mode indicates the type of application that the user is currently preparing to run, and the working mode includes graphics mode and audio and video mode, so The server can reduce the transmission bit rate of the data types that the user does not care about according to the priority, which can guarantee the user experience to a greater extent.

In an application scenario, when the working mode of the client is a graphics mode. As shown in Figure 3, the method may include:

301. Acquire the rendering delay of the graphics data.

Among them, when the working mode of the client is the graphics mode, it indicates that the user currently has relatively high quality requirements for the graphics data. For example, if the application currently running on the client is a precision drawing application, the client can obtain the rendering delay of the graphics data. The rendering time point at which graphics data can be collected and started rendering can be obtained by subtracting the time stamp of the graphics data from the rendering time point to obtain the rendering delay of the graphics data.

302. Determine the relationship between the rendering delay and the preset delay threshold. When the rendering delay is greater than the first delay threshold, perform steps 303-305; when the rendering delay is less than the second delay threshold, perform steps 306 - step 308 .

Wherein, after the rendering delay is obtained, the relationship between the rendering delay and the preset delay threshold can be judged, wherein the delay threshold includes a first delay threshold and a second delay threshold, and the first delay The threshold is greater than the second delay threshold.

303. Send to the server a first flow control request for requesting the server to reduce the transmission bit rate of the audio and video data.

Among them, since the current working mode of the client is the graphics mode, when it is judged that the rendering delay is greater than the first delay threshold and the server needs to be requested to reduce the transmission bit rate, the server can be requested to first reduce the transmission bit rate of audio and video data, or That is to say, the client sends the first flow control request to the server to request the server to reduce the transmission bit rate of audio and video data. When the server receives the first flow control request sent by the client, it can try to reduce the transmission bit rate of audio and video data. , so as to ensure that the client can obtain enough graphics data in time. Wherein, the specific method for the server to reduce the transmission bit rate of the audio and video data may be to discard part of the data and not send it to the client.

Optionally, when the server receives the first flow control request sent by the client to request the server to reduce the transmission bit rate of the audio and video data, but the current transmission bit rate of the audio and video data is already the lowest, that is to say, the server lowers the audio and video data rate. If the transmission code rate of the video data fails, the server can send a flow control failure response to the client, and the client receives the flow control failure response, that is, executes the following step 304 .

304 . Receive a flow control failure response sent by the server. The flow control failure response is sent when the server fails to reduce the transmission bit rate of the audio and video data.

Wherein, when the server fails to reduce the transmission bit rate of audio and video data, it will send a flow control failure response to the client, and at this time, the client can receive the flow control failure response sent by the server.

305. Send a third flow control request for requesting the server to reduce the transmission code rate of the graphics data to the server, so that the server adjusts the transmission code rate of the graphics data according to the third flow control request.

Among them, when the client receives the flow control failure response sent by the server, the client knows that the transmission code rate of the audio and video data is already the lowest. At this time, the client can send the transmission code used to request the server to reduce the graphics data to the server. rate of the third flow control request, when the server receives the third flow control request, it can reduce the transmission bit rate of the graphics data according to the received third flow control request, if the transmission bit rate of the graphics data is already the lowest, Then the server sends graphics data to the client according to the current transmission code rate. Wherein, the specific method for reducing the transmission code rate of the graphics data may be to reduce the compression level of the graphics and/or change the size of the graphics.

306. Send a second flow control request to the server for requesting the server to increase the transmission code rate of the graphics data.

Wherein, when it is judged that the rendering delay is less than the second delay threshold, in order to make full use of the bandwidth at this time, the server can be requested to increase the transmission bit rate. Since the working mode of the client is graphics mode at this time, the server can be preferentially requested to increase the graphics data. transmission code rate, that is, the client may send a second flow control request to the server for requesting the server to increase the transmission code rate of the graphics data. When the server receives the second flow control request sent by the client, it may try to increase the transmission bit rate of the graphics data, so as to fully utilize the network bandwidth and enable the user to obtain a better experience. A specific method for increasing the transmission code rate of the graphics data may be to increase the compression level of the graphics data and/or change the size of the graphics.

Optionally, when the server receives the second flow control request sent by the client to request the server to increase the transmission code rate of the graphics data, but the current transmission code rate of the graphics data is already the highest, that is to say, the server increases the graphics data transmission rate. If the data transmission code rate fails, the server can send a flow control failure response to the client at this time, and the client receives the flow control failure response, that is, executes the following steps 307,

307. Receive a flow control failure response sent by the server, and the flow control failure response is sent when the server fails to increase the transmission code rate of the graphics data.

Wherein, when the server fails to increase the transmission bit rate of the graphics data, the client receives the flow control failure response sent by the server.

308. Send a third flow control request for requesting the server to increase the transmission code rate of the audio and video data to the server, so that the server adjusts the transmission code rate of the audio and video data according to the third flow control request.

Among them, when the client receives the flow control failure response sent by the server, the client knows that the server has increased the transmission code rate of graphics data to the highest level, and at this time the client can send the transmission code used to request the server to increase the audio and video data to the server. rate of the third flow control request, when the server receives the third flow control request sent by the client, it can increase the transmission bit rate of the audio and video data according to the third flow control request, if the transmission bit rate of the audio and video data is already is the highest, the server sends audio and video data to the client according to the current transmission bit rate.

Optionally, the above steps 301 to 308 can be executed repeatedly, so that the server can dynamically adjust the transmission bit rate of graphics data and audio and video data according to the current bandwidth usage to improve user experience.

In another application scenario, when the working mode of the client is audio and video mode. As shown in Figure 4, the method may include:

401. Obtain the playback delay of the audio and video data.

Wherein, when the working mode of the client is the audio and video mode, it indicates that the user currently has relatively high requirements on the quality of audio and video data. For example, the user needs to play audio and video files, so the client can obtain the playback delay of the audio and video data.

402. Determine the relationship between the playback delay and the preset delay threshold. When the playback delay is greater than the first delay threshold, perform steps 403 to 405; when the playback delay is less than the second delay threshold, perform step 402. 406 - step 408 .

403. Send to the server a first flow control request for requesting the server to reduce the transmission code rate of the graphics data.

Wherein, since the current working mode of the client is the audio and video mode, when it is judged that the playback delay is greater than the first delay threshold, the client can send to the server a first flow control message for requesting the server to reduce the transmission bit rate of the graphics data. Request, that is, to make the server give priority to reducing the transmission bit rate of graphics data.

Optionally, when the server fails to reduce the transmission bit rate of the graphics data, it may send a flow control failure response to the server, and the client may receive the flow control failure response, that is, perform the following step 404 .

The data transmission code rate is adjusted.

406. Send to the server a second flow control request for requesting the server to increase the transmission bit rate of the audio and video data.

Wherein, when it is judged that the playback delay is less than the second delay threshold, and since the working mode currently set by the client is the audio and video mode, the server may be requested to limitly increase the transmission bit rate of the audio and video data, that is, the client sends the audio and video data to the server. The second flow control request is for requesting the server to increase the transmission bit rate of the audio and video data, so that the server can increase the transmission bit rate of the audio and video data.
