Abstract

Systems for transmitting information from terminal systems (1) via access multiplexers (3) comprising virtual forwarder systems (5) to networks are made less complex by inserting at the terminal systems (1) virtual forwarder internet protocol addresses (35,64,66) into destination fields of internet protocol headers for heading the information and by inserting destination internet protocol addresses (36,37,38,65,67) into routing fields of the internet protocol headers. Both the terminal systems (1) and the access multiplexers (3) should be made capable of dealing with internet protocol headers of the internet protocol version-4 or the internet protocol version-6 or higher, which comprise a destination field and a routing field. The destination internet protocol addresses (36,37,38,65,67) in the routing fields allow distinguishment between different classes of services and/or applications used by the terminal system (1) simultaneously, without the access multiplexers (3) being obliged to unpack (parts of) the information and to detect (parts of) the information at higher layers.
