ABSTRACT:
An Asynchronous Transfer Mode (ATM) switching device handles active and passive leaves. For a multicast connection being routed through the switching device, there is set up both a passive leaves queue (PLQ) for each physical output link and a leaf table for each leaf of the multicast connection. The leaf tables are added and removed for each connection on the fly as each leaf is added or removed. For a passive leaf of the multicast connection, the leaf table for the passive leaf is linked to an appropriate one of the passive leaves queues. However, upon reception of a cell from a switch core, the appropriate one of the passive leaves queues is activated by being linked to an activation queue (AQ). Thereafter a pointer is set, in an active leaves queue (ALQ), to the leaf table indicated in the appropriate passive leaves queue (PLQ). There is an active leaves queue for each physical output.
