Optimization method and device for bandwidth usage

Abstract

The embodiment of the invention discloses an optimization method and device for bandwidth usage, relates to the field of communication, and ensures that user experience is improved as graphics applications and media applications of the client side can obtain enough data timely. The invention adopts the specific scheme that the optimization method comprises the steps as follows: acquiring a data processing time delay; judging relationship of the time delay and a preset time delay threshold, wherein the time delay threshold comprises a first time delay threshold; and when the time delay is greater than the first time delay threshold, sending a first flow control request used for requesting the server to reduce transmission bit rate to the server, so as to enable the server to reduce the transmission bit rate conveniently via the first flow control request, and further enable the client side to obtain enough data timely. The optimization method and device are applied to the optimization process of bandwidth usage.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for optimizing bandwidth usage. Background technique [0002] 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. [0003] 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...

Problems solved by technology

[0004] 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
