<p>An apparatus and method for transmitting multi-protocol label switching (MPLS) multicast packets over Ethernet are provided. The apparatus and method determine whether a received packet is an MPLS multicast packet; determine whether an address of the received packet exists in a database storing address information for MPLS multicast packet transmission; determine which node the MPLS multicast packet whose address exists in the database is transmitted to and allocating an MPLS label according to the address of the determined node; and map the allocated MPLS label to an Ethernet destination MAC address of the packet in order to realize simple switching by mapping an MPLS label, rather than a conventional IP address, to an Ethernet destination medium access control (MAC) address, thereby utilizing advantages of an MPLS network.</p> |
