Abstract:
A traffic shaping method in an ATM network, comprising:a traffic shaping and controlling step of performing a traffic shaping operation on input ATM cells, and controlling a rate of ATM cells to be outputted from an ATM network apparatus; a converting step of converting an ATM cell's frame period, whose output rate has been controlled by the traffic shaping step, from internal operation-frames to external-operation frames; and a supervising step of supervising a transmission rate of the ATM cells outputted in the converting step; wherein the supervising step includes a step of supervising the output rate of the ATM cells, and when the average rate exhibits a drop, transmitting output rate information for use in the traffic shaping operation for causing the traffic shaping and controlling operation to be performed until the average rate rises to a maximum rate set in advance.
