Abstract
An ATM system including a switch unit having a plurality of input/output ports and a plurality of interface units connected to the respective input/output ports of the switch unit, each of the interface units mutually generating an internal communication cell with information necessary for rate control of an ATM traffic added thereto, inserting the cell into a free band of a user traffic and sending the same to all the interface units through the switch unit to interchange rate control information between the respective interface units, thereby conducting rate control of an ATM traffic by which equal throughputs can be obtained among connections.
