Abstract
The present invention is to provide a cell discard control system for an ATM (asynchronous transfer mode) cell buffer capable of preventing useless cells which are not restored to an original packet from being transmitted to an ATM network and minimize a discarded number of packets which should not be discarded. It comprises a cell receiving section 11 having a packet identifier adding part 11a for adding a packet identifier for identifying being cellulated from the same packet for an input cell and a cell discard part 11b for discarding cells, a cell buffer 12 for buffering cells transferred from the cell receiving section 11, the cell transmitting section 13 for transmitting cells transferred from the cell buffer 12 to an ATM network and transmitting idle cells instead of discarded cell which have been discarded by a cell discard part 13a, and buffer controller 14 for detecting a packet identifier added to a cell being discarded due to over flow of the cell buffer 12 and instructing the cell receiving section 11 and the cell transmitting section 13 to discard cells having the same packet identifier being detected.
