Various arrangements for increasing a transfer rate of a data transfer via satellite are presented. A satellite gateway may set an accelerated set of communication parameters that control communication between the satellite gateway and the satellite terminal via the satellite and between the satellite gateway and the content source to an accelerated transfer rate between the content source and the satellite terminal. A first set of data may be transferred from the content source to the satellite terminal using the set of communication parameters. After transferring the first set of data, the satellite gateway may adjust the initial set of communication parameters to an adjusted set of communication parameters. The adjusted transfer rate can be lower than the accelerated transfer rate.
