1. A method for bi-directionally transmitting a data packet during data transmission between a first communication appliance and a second communication appliance comprising the steps of:
forming the data packet to be transmitted from the first communication appliance to the second communication appliance, wherein the data packet contains packet data and a piece of acknowledgement information indicating an acknowledgement status of each data packet of a set of data packets already previously received by the first communication appliance during data packet transmission, transmitting the data packet formed from the first communication appliance to the second communication appliance, and re-transmitting an unacknowledged data packet using a different physical communication link than a physical communication link used for initially sending the unacknowledged data packet from the first communication appliance to the second communication appliance; wherein, when each data packet in the set of data packets from the data transmission have been received by the first communication appliance and the second communication appliance using a plurality of physical communication links, further transmitting a final data packet from the first communication appliance to the second communication appliance using all of said plurality of physical communication links concluding or terminating the data transmission.
