Abstract

In a method for transferring data packets in a communication network, first data packets having a low priority are transferred between a transmitter and a receiver and second data packets having a high priority compared to the first data packets are preferably transferred between them. In a second data packet to be transferred it is checked whether presently a first data packet is being transferred. If yes, the transfer of the first data packet is interrupted or stopped and the second data packet is then transferred. After the transfer of the second data packet, the transfer of the un-transferred first data packet is repeated or the rest of the incompletely transferred first data packet is transferred. Each first data packet is stored in an intermediate memory in parallel with a transmission and is only deleted from the intermediate memory after complete transfer of the first data packet to the receiver.
