Abstract
A method for providing IP multicast service using a VLAN in a network including an IP multicast/VLAN manager for supporting an IGMP and a GVRP, and multicast group members, includes: after generating an IP multicast group, allowing a sender to request the IP multicast/VLAN manager to search for at least one host joining the IP multicast group; allowing the IP multicast/VLAN manager to check whether the host supports the VLAN; and allowing the sender to transfer a packet through the VLAN if the host joining the IP multicast group supports the VLAN and allowing the sender to broadcast a packet though IP multicast if not.
