ABSTRACT:
A destination address retrieving system generates a retrieval key from a header information of a packet and performs a retrieval to an address information table based on the key and receives a returned value. If the returned value indicates the presence of any internal header, then the address retrieving unit further generates another retrieval key from an internal header information of the packet, for performing another retrieval to another address information table.
