ABSTRACT:
Disclosed is an ATM switch which comprises: an ATM switch unit; a switch control unit for controlling the ATM switch unit; one or more circuit accommodation units for connecting the switch with one or more external ATM networks, respectively, and an IP routing process unit for routing IP packets in a form of ATM cells. In the ATM switch, the IP routing process unit may comprise: a cell storage unit having a plurality of memories; a distributing means for distributing the ATM cells received from the ATM switch unit to the plurality of memories while grouping the ATM cells into each of the plurality of memories in accordance with an IP packet to which each of the ATM cells belongs; sending means for sending all the ATM cells belonging to an identical IP packet when the all the ATM cells belonging to the identical IP packet have been stored in respective one of the plurality of memories; and means for converting VPI/VCI (Virtual Path Identifier/ Virtual Channel Identifier) of the all the ATM cells belonging to the identical IP packet.
