Wherein, delay when handling current data when client gets access to, just can judge the magnitude relationship of this time delay and default time delay thresholding, the occurrence of this time delay thresholding can obtain according to the bandwidth of network.
103, when time delay during greater than the first time delay thresholding, send to server and to be used for the first-class control request that request server reduces transmission code rate, so that server reduces transmission code rate according to the first-class control request, and then make client in time obtain enough data.
Wherein, because in the desktop cloud system, server adopts fixing compression parameters deal with data, so data volume of control chart graphic data dynamically, the transmission rate of adding graph data and audio, video data does not have controlling mechanism yet, so server depends on the transmission code rate of graph data and audio, video data to the bandwidth usage of client transmissions data.When the client judgement obtains time delay greater than the first default time delay thresholding, that is to say when time delay is excessive, just show the bandwidth deficiency, client can send to server and be used for the first-class control request that request server reduces transmission code rate this moment, when server receives the first-class control request of client transmission, just can reduce the transmission code rate of data according to the first-class control request, be cost with certain graph image quality like this, reduce data volume and improve the refresh rate of graphical application and the broadcast fluency of media application, thereby guaranteed under the situation of bandwidth deficiency, client still can get access to enough data timely, guarantees user's experience.Wherein, what the transmission code rate of reduction data was concrete can be the transmission code rate that reduces graph data, also can be the transmission code rate that reduces audio, video data, can also be the transmission code rate that reduces graph data and audio, video data simultaneously.
The bandwidth that the embodiment of the invention provides is used optimization method, the time delay that the data that get access to by judgement are handled and the magnitude relationship of default time delay thresholding are known the operating position of current network bandwidth, and obtain time delay greater than the first time delay thresholding in judgement, when being network bandwidth deficiency, send the first-class control request that is used for request server reduction transmission code rate to server, so that server reduces transmission code rate according to the first-class control request, and then make client can obtain enough data timely, make under the situation of network bandwidth deficiency, the graphical application of client and media application can in time obtain enough data, have improved user's experience.
Another embodiment of the present invention provides a kind of bandwidth to use optimization method, and as shown in Figure 2, this method can comprise:
201, obtain the data processing delay.
202, judge the magnitude relationship of time delay and default time delay thresholding, when time delay during greater than the first time delay thresholding, carry out following steps 203; When time delay during less than the second time delay thresholding, carry out following steps 204.
Wherein, client can arrange the first time delay thresholding and the second time delay thresholding in advance according to the bandwidth of network, wherein the first time delay thresholding is used for judging whether current bandwidth is not enough, the second time delay thresholding is used for judging whether current bandwidth has surplus, and the first time delay thresholding is greater than the second time delay thresholding.
203, send the first-class control request that is used for request server reduction transmission code rate to server, so that server reduces transmission code rate according to the first-class control request, and then make client in time obtain enough data.
204, send second flow control request that is used for request server raising transmission code rate to server, so that server improves transmission code rate according to second flow control request.
Wherein, when the judgement of client obtains time delay less than second thresholding, that is to say when current bandwidth is abundant, client just can send to server and be used for second flow control request that request server improves transmission code rate this moment, when server receives second flow control request, just can improve the transmission code rate of data according to second flow control request, thus the bandwidth of fully using network to provide.Wherein, what the transmission code rate of raising data was concrete can be the transmission code rate that improves graph data, also can be the transmission code rate that improves audio, video data, can also be the transmission code rate that improves graph data and audio, video data simultaneously.
Need to prove, the bandwidth that the embodiment of the invention provides is used the specific descriptions of step 201-step 204 in the optimization method, can be with reference to the specific descriptions of corresponding step in the step 101-step 103 in another embodiment of the present invention, the embodiment of the invention is not to give unnecessary details one by one.
The bandwidth that the embodiment of the invention provides is used the method for optimizing, the time delay that the data that get access to by judgement are handled and the magnitude relationship of default time delay thresholding are known the operating position of current network bandwidth, and obtain time delay greater than the first time delay thresholding in judgement, when being network bandwidth deficiency, send the first-class control request that is used for request server reduction transmission code rate to server, so that server reduces transmission code rate according to the first-class control request, and then make client can obtain enough data timely, make under the situation of network bandwidth deficiency, the graphical application of client and media application can in time obtain enough data, have improved user's experience.
And, can two time delay thresholdings be set in client, and when the client judgement obtains time delay less than the second time delay thresholding, send second flow control request that is used for improving transmission code rate to server, so that server improves transmission code rate, make the network bandwidth be fully utilized.
Another embodiment of the present invention provides a kind of bandwidth to use optimization method, because under the situation of bandwidth deficiency, server is that the quality with graph image is cost, can in time get access to enough data by picture application and the media application that reduces data volume assurance client, to guarantee user's viewing experience, the user can arrange different mode of operations in client in embodiments of the present invention, this mode of operation represents that the user prepares the type of the application that moves at present, this mode of operation comprises graphic model and audio frequency and video pattern, server just can guarantee greatly that the user experiences according to the transmission code rate of the current data type of not paying close attention to of preferential reduction user like this.
In a kind of application scenarios, when the mode of operation of client is graphic model.As shown in Figure 3, this method can comprise:
301, obtain the time delay of playing up of graph data.
Wherein, when the mode of operation of client is graphic model, show that the current quality requirement to graph data of user is than higher, such as current be accurate application of drawing in client operation, client can be obtained the time delay of playing up of graph data so, concrete can gather the render time point that graph data begins to play up, and deducts the timestamp of graph data then with this render time point, just can obtain the time delay of playing up of graph data.
302, judge the magnitude relationship of the time delay thresholding of playing up time delay and presetting, when playing up time delay greater than the first time delay thresholding, execution in step 303-step 305; When playing up time delay less than the second time delay thresholding, execution in step 306-step 308.
