Abstract

A method and a device for estimating available transmission bandwidth on a network connection over which data files are to be transmitted within a predetermined transmission time. A data file size is determined for a first data file to be transmitted over the network connection and a lowest average bitrate required to transmit the first data file within the predetermined transmission time is determined by dividing the data file size by the predetermined transmission time. A transmission time of the first data file is divided into one or more first time intervals and one or more second time intervals, wherein each of the one or more first time intervals is followed by a second time interval of the one or more second time intervals unless the first time interval is a last time interval. Data of the first data file are transmitted over the network connection during the one or more first time intervals at a bitrate higher than the determined lowest average bitrate. Remaining data of the first data file are transmitted over the network connection during the one or more second time intervals at a bitrate lower than the bitrate during the one or more first time intervals. The bitrate during the one or more second time intervals is such that a resulting average bitrate of the transmission of the first data file is equal to or higher than the determined lowest average bitrate but lower than a bitrate threshold. An available transmission bandwidth over the network connection is estimated based on feedback on the transmission of data of the first data file over the network connection during the one or more first time intervals at the bitrate higher than the determined lowest average bitrate.
