Method and apparatus for multicasting in common memory switches |
摘要 |
<p>Methods, systems, and networks for tracking multicast cell copies in a switch. The switch includes a plurality of output ports each having an associated output port register, and a port memory controller for receiving a bit map on the enqueue of a cell into the switch. The bit map includes a bit for each output port register. The port memory controller writes to each output port register the bit from the bit map for that port register. The value of a bit in an output port register indicates whether a copy of the enqueued cell is to be transmitted from the output port associated with that output port register. <IMAGE></p> |
