System comprising a terminal system, an access multiplexer and a network
First Claim
1. An access multiplexer for use in a system for transmitting information from a terminal system via the access multiplexer to a network coupled to the access multiplexer, which access multiplexer comprises a virtual forwarder system, wherein the access multiplexer further comprises:
- a sender for sending˜
to the terminal system, a virtual forwarder internet protocol address defining at least a part of the virtual forwarder system anda receiving means for receiving˜
from the terminal system, the information˜
to be transmitted to the network wherein the virtual forwarder internet protocol address is in a destination field of an internet protocol header of the information and a destination internet protocol address is in the internet protocol header, the destination internet protocol address defining a destination in the network coupled to said access multiplexer.

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.
