Patent ID: 7352754

Claim:
An ATM-based device comprising: a data transmitter including a transmission data storage unit configured to store data received from a calculation processing module; a cell generator configured to divide a message stored in the transmission data storage unit into a predetermined amount of data, to combine the data using Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI) information attached to the message to generate at least one ATM cell; and a cell transmitter configured to transmit the at least one ATM cell generated at the cell generator to an ATM switch; and a data receiver including a cell receiver configured to receive the at least one ATM cell switched by the ATM switch module; a memory controller configured to control storage of the at least one ATM cell received by the cell receiver to a corresponding cell buffer according to a cell buffer identifier; a memory configured to store the at least one ATM cell; a data restoring unit configured to retrieve the at least one ATM cell using the cell buffer identifier and to restore the message; and a receiving data storage unit configured to store the message restored by the data restoring unit.
