ABSTRACT:
In a traffic control method and system for an ATM switching apparatus, which is adapted to control traffic by restraining inflow cells on the basis of an amount of cells remaining in a queuing buffer that receives a varying amount of inflow cells and outputs a constant amount of outflow cells, a residual cell amount in the queuing buffer is monitored at intervals of unit times. The cell variation amount of cells remaining in the queuing buffer is monitored per unit time. It is determined, on the basis of the residual cell amount monitoring result and the cell variation amount monitoring result, whether a residual cell amount after the lapse of a predetermined period of time exceeds a cell residue limit amount in the queuing buffer. Inflow cells to the queuing buffer are restrained when it is determined that the residual cell amount exceeds the cell residue limit amount.
