TRAFFIC SHAPING FOR FRAME AND IP PACKETS IN AN ENTERPRISE SWITCH

摘要

An ATM switch for directing traffic flow of native ATM cell traffic and frame based packets between an input and an output port of the switch comprises a device for receiving native ATM cells and transporting the native ATM cells to the output port for output at a switch output rate; a device for receiving the frame based packets; a device for segmenting each received frame based packet into a corresponding plurality of ATM cells and transmitting the plurality of ATM cells to the output port at an ATM cell transmission rate; and a control device for controlling the ATM cell transmission rate to enable reduction of ATM cell loss at the output port and corresponding frame relay packet loss at the expense of packet delay.
