ABSTRACT:
A flow control apparatus is connected to an ATM switch having a plurality of input ports and a plurality of output ports provided among ATM exchanges through transmission links. A buffer is connected to the input port and temporarily stores ATM cells output from the ATM switch, wherein the ATM cells are transmitted through the ATM switch to the output port connected to a next ATM exchange. A controller sets up the ATM switch wherein first-free information cells conveying the free-buffer information of the buffer input to the input port are transmitted to the output port connected to a preceding ATM exchange. The controller also controls transmission of the ATM cells from the buffer based on second free-buffer information cells transmitted from the next ATM exchange and traffic parameters for guaranteeing transmission quality.
