Abstract: The invention relates to a device, in particular a router, for bundling a plurality of Internet access lines into a virtual Internet access line for the purpose of providing the sum of the bandwidths of the plurality of Internet access lines for a transmission of data via the virtual Internet access line, wherein the device divides a data packet to be transmitted among a plurality of data packets for separate transmission via the plurality of Internet access lines, wherein the device is designed to calculate redundancy information and to transmit said redundancy information along, from which redundancy information lost data packets can be restored, such that packet losses on an Internet access line do not lead to packet losses on the bundled virtual line.

Abstract: The present invention relates to a system for transmitting a data flow (a) from a transmitter device (1) to a receiver device (2) via a network (3) with a packet-based transmission protocol, in particular via the TCP/IP-based internet, with the devices (1) and (2) being connected to the network via network access links (4,4?) and with a plurality of network access links (4,4?) for bundling being disposed on the side of the transmitter device and/or receiver device, with an auxiliary transmitter device (5) being interconnected between the transmitter device (1) and the network access link(s) (4) and with an auxiliary receiver device (6) being interconnected between the network access link(s) (4?) and the receiver device (2). The present invention also relates to a method of transferring a data flow via bundled network access links as well as to an auxiliary transmitter device and to an auxiliary receiver device and to a transmission and receiving method therefore.
