A communication system comprises: a control apparatus that sets broadcast domains or multicast domains respectively for virtual networks configured in a physical network including a forwarding node(s), and sets, in the forwarding node(s), broadcast or multicast control information, associating a packet forwarding destination and a match condition including an identifier for identifying one of the broadcast domains or multicast domains; and the forwarding node(s) that performs a broadcast or multicast using the broadcast or multicast control information. A broadcast or multicast is implemented in an OpenFlow network without being constrained by the number of VLAN IDs, and with fewer flow entries. |
