ATM switching system and cell control method

A method in an ATM communication apparatus for treating ATM cells including a plurality of ATM cells belonging to burst data, said method comprising the steps of:

• storing in a buffer memory, coupled to a plurality input and a plurality of output lines, ATM cells received from said input lines;
• and
• transferring ATM cells from said input lines to one of said output lines through said buffer memory in accordance with header information of each of the ATM cells, or discarding a series of ATM cells of burst data before storing said series of ATM cells of burst data in said buffer memory, said series of ATM cells beginning from a first ATM cell of the burst data, based on an amount of other burst data passing to said one of said output lines.
