Device to regulate the flow of ATM cells within an ATM packet switch
First Claim
1. A regulating device to regulate the flow of ATM cells within an ATM packet switch including a multiplexer associated with a specified number of input and output buffers and a control device to control the internal flows of ATM cells informing the input buffers of the state of congestion of the output buffers, said regulating device comprising means to convert the flow of sporadic point-to-multipoint cells, arriving at the input of the input buffers, into a regular flow of point-to-multipoint cells towards the multiplexer irrespective of the outgoing direction taken by the cells and independently for each input.
