Abstract (en)

[origin: WO9634469A1] An ATM network switch includes a switch fabric (14), and a plurality of slot controllers (11) coupled to the switch fabric. Each slot controller has at least one external data link (12, 13), cell receiving circuitry (21) for receiving ATM cells from the data link and cell transmitting circuitry (22) for transmitting ATM cells outwardly on the data link. The cell transmitting circuitry of each slot controller includes traffic shaping circuitry (23) arranged to set, for each cell presented to the transmitting circuitry, a current onward transmission time where onward transmission at the input rate meets a predetermined flow rate criterion, and a delayed onward transmission time where onward transmission at the current time would cause the traffic on a VC to exceed a predetermined flow rate criterion. The traffic shaping circuitry includes a buffer (24) which stores each new cell at an address corresponding to the onward transmission time, and output logic (32 or 44) for outputting cells from the buffer at a time corresponding to the address thereof.
