ADAPTIVE ROUTER ARCHITECTURE USING LOGICAL INTERNAL ADDRESSING

摘要

A method and a related router comprising a network interface, a logical addressing module and a forwarding element card. The logical addressing module is capable of maintaining at least one local table associating at least one card of the router with at least a portion of at least one service provided by the router. The forwarding element card is capable of receiving a packet stream on the network interface, detecting that the packet stream requires further treatment from a further card of the router and, upon detection, consulting the local table to find an identifier, to which the further card is linked, based on information found in the packet stream before forwarding the packet stream toward the further card.
