A technique for forwarding multi-cast data packets in a communication network. Multi-cast packets are broadcast to every output port of the switch. The packet is thus buffered in each port. Then, all of the output ports, save those that are appropriate output ports for the packet, drop the packet. Accordingly, the output ports that did not drop the packet forward the packet to the network. A control packet that follows the packet may then instruct the ports regarding which ports are to drop the packet and which ports are to forward the packet. This technique has an advantage of efficiently handling multi-cast packets.
