<p>The present invention provides for an identifier distinguishing unit 14 serving to distinguish the identifier contained in a packet and a VC (virtual connection) search processing unit 13 which searches the identifier/VC management table 12 using that identifier as the search character sequence. A VC selecting unit 15 selects an ATM VC for use in transmission the basis of the ID information on ATM VCs resulting from the search and a cell formation processing unit 16 subjects the packet to ATM self format conversion processing. Also provided is a frame formation processing unit 24 which regenerates individual packets from packet information and a VC distinguishing unit 25 distinguishes the ID information on ATM VCs pertaining to each individual packet. An identifier search processing unit 23 searches the VC/identifier management table 22 using the ID information on ATM VCs as the search character sequence. An identifier assigning unit 26 assigns the identifier resulting from the search to the packet, and supplies that packet and so it becomes possible to comprehensively manage packets transferred across a plurality of packet networks having different identifier management policies.</p> |
