Abstract

The invention discloses a bandwidth estimating method, device and system. The method comprises the following steps: receiving a bandwidth detection data packet transmitted by an auxiliary unit; traversing the bandwidth detection data packet after receiving the bandwidth detection data packet, and judging whether bandwidth detection data packet receiving times satisfy a preset condition or not; and acquiring a corresponding bandwidth according to a judgement result. Through adoption of the bandwidth estimating method, device and system, the technical problem of low measurement accuracy in an implementation process of a detection method in the prior art is solved.

Description

technical field [0001] The present invention relates to the application field of communication technology, in particular, to a bandwidth estimation method, device and system. Background technique [0002] In the video transmission, the smoothness of the transmitted image at the source end and the destination end is affected by many factors, such as the codec rate and the image transmission rate. The present invention is studying the factors affecting the image transmission rate in the network-existing network bandwidth- Under the premise of , an improvement to the existing bandwidth measurement algorithm pathchirp is proposed, so that it can provide a usable value for the sending rate of the video sent by the sender in video transmission, so that it can be transmitted as much as possible in video transmission The largest amount of data, so that the receiving end can process the video more smoothly, and the receiving end will not be in a state of starvation, so that the recei...
