Abstract
In the transfer of information packets in a network the information (7) is transmitted by the sending terminal station (1A) provided with a destination address field (9). The destination address field (9) comprises references or codes of the input lines/output lines or connection lines which are to be used when the information packet is retransmitted from nodes (5) in the network. In the corresponding way each information packet is in a node provided with address information in a return address field (11) indicating the connection line or combined input line/output line on which the information packet arrived to the node (5). Thereby the information packet, in a simple way, is provided with a return address and it may be utilized by the receiving terminal station (1B) for instance for the transfer of a receipt message.
