An access node () that is preferably a Flow-Aware Ethernet DSLAM configured to transmit Ethernet data frames between subscribers () and an aggregation network (). The access node comprises a first memory () for storing classification rules and a second memory () for storing flow rules. These rules are applied by a classification agent () and by a service agent () to information extracted from incoming data frames in order to infer flow awareness information of outgoing frames corresponding to these incoming data frame. In this way, the subscriber access network evolves to a multi-service architecture by replacing ATM with Ethernet for cost reasons. The concept of 'flow awareness' is applied to the present access node. With respect to known tunnel-based Ethernet DSLAMs, the present access node removes all dependency on correct encapsulation or labeling at the customer side and at the service provider side.

Systems for transmitting information from terminal systems () via access multiplexers () comprising virtual forwarder systems () to networks are made less complex by inserting at the terminal systems () virtual forwarder internet protocol addresses () into destination fields of internet protocol headers for heading the information and by inserting destination internet protocol addresses () into routing fields of the internet protocol headers. Both the terminal systems () and the access multiplexers () 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 () in the routing fields allow distinguishment between different classes of services and/or applications used by the terminal system () simultaneously, without the access multiplexers () being obliged to unpack (parts of) the information and to detect (parts of) the information at higher layers.
