Embodiment Construction
[0048]V-Switch technology is very suitable for carrying unicast and point-to-point services, but it is difficult to carry multicast, broadcast and multipoint-to-multipoint services. However, the existing Ethernet technology is based on MAC address learning and forwarding, and is relatively mature in carrying multicast, broadcast, and multipoint-to-multipoint services.
[0049] Therefore, the present invention proposes a method for the coexistence of the V-Switch function of the DRE device and the existing Ethernet function. The two technologies can be mixed in a network, and different services can be carried according to the advantages of the two technologies. Therefore, on the premise of maintaining the simplicity of V-Switch technology, the problem of carrying services such as multicast, broadcast, and point-to-multipoint in actual networking is solved.
[0050] For this reason, the present invention enables the interface of the V-Switch function of the DRE to work in two m...
