摘要： A method is disclosed for facilitating multicast operation in a network in which a data unit is multicast from a root node to a plurality of leaves via a plurality of branching point nodes in response to feedback processed at each branching point node. At least one cell forwarding technique is selected from a plurality of cell forwarding techniques at the respective branching point nodes. The cell forwarding techniques facilitate multicast operation by controlling forwarding and discard of multicast cells. The forwarding techniques are realized via use of a ring buffer (35) in which cells are stored prior to forwarding. Manipulating head (37) and tail (39) pointers associated with the ring buffer (35) allows for a plurality of desirable forwarding techniques.
