Embodiment Construction
[0024] The specific process of the method is described below in conjunction with the accompanying drawings.
[0025] As shown in Figure 1, the server's automatic bandwidth detection module uses the amount of data sent to the client within a period of time to test the current available bandwidth of the server, and the client's automatic bandwidth detection module counts the layers of layered coded messages received in the latest period Quantity, using an exponential weighting method to predict the current available bandwidth. The specific algorithm is as follows:
[0026] The data received by the client is Layer, the client maintains a timer, which is used to trigger bandwidth detection at regular intervals. A receiving window is defined between two triggers of the timer, and the client counts the actual received quantity B of data of each layer in the i-th receiving window. i j , and predict the available bandwidth at the next moment by weighting C ...
