METHOD AND SYSTEM FOR ADDRESSING AND ROUTING IN ENCRYPTED COMMUNICATIONS LINKS

摘要

The invention relates to a method and a system (11) for addressing and routing using encrypted communications links (1) in at least two different network layers (2, 3) of a network which are separated from each other by different routing layers. A first network layer (2) with the associated first routing layer is demarcated relative to a second network layer (3) with a second routing layer by means of at least one encryption device (4). In the at least two routing layers, a network topology of both network layers (2, 3) is worked out independently of one another and stored in corresponding routing tables (17). An interface (7) in the at least one encryption device (4) is provided with a unique assignment of addresses (8) of the second routing layer to addresses (8) of the first routing layer, in order to derive the topology of the second network layer (3) from the first network layer (2) efficiently.
