ABSTRACT:
A method controls multicast cell access to a switching network with a reservation ring in an ATM (Asynchronous Transfer Mode) switch. The switching network distributes the multicast cell in one or more passes from an input channel to one or more output channels of the switch during a switch cycle. An arbitration session for a multicast cell begins by submitting an arbitration request identifying a set of destination output channels to the reservation ring. During an arbitration cycle, the output channels in the set of destination output channels are arbitrated for over the reservation ring. The arbitration request is reissued during later arbitration cycles until access to each of the destination output channels in the set of output channels is granted.
