Abstract
In a communication system a network switch (4) is coupled to an access network (1) in order to enable communication between a network (2) and terminals (13) connected to the access network (1). In the prior art communication system, the network switch needs to know the details of the access network, in order to be able to deliver information to the correct terminal. This requires that a dedicated network switch (4) is used which is substantially more complex than a standard network switch. To solve this problem, an access node switch (8) is used which deals with the access network specific details. Consequently a network switch (4) can be used which operates according to standard switching protocols.
Claims8
Communication system comprising a plurality of terminals which are connected to a network switch via an access network, the access network comprising an access node coupled to the terminals via a transmission network, the access node further being coupled to the network switch, characterized in that the access node comprises an access node switch and a plurality of network control elements, in that the access node switch is coupled to the network switch and to the plurality of network control elements, in that the transmission network comprises a plurality of sub-networks, and in that the network control elements are coupled to the plurality of sub-networks.
Access node coupled being connectable to a transmission network, and to a network switch, characterized in that the access node comprises an access node switch being coupled to a plurality of network control elements, in that the access node switch is connectable to the network switch and in that the network control elements are connectable to a plurality of sub-networks.
