  • determining, by the master node, a virtual port corresponding to a virtualization packet;

    adding, by the master node, a first layer virtual local area network (VLAN) tag to the virtualization packet according to the determined virtual port corresponding to the virtualization packet;

    sending, by the master node, the virtualization packet to the egress AP remote from the master node according to the first layer VLAN tag;

    determining, by the egress AP, a remote network element port corresponding to the virtualization packet according to the first layer VLAN tag;

    removing, by the egress AP, the first layer VLAN tag from the virtualization packet; and

    sending, by the egress AP after the removing, the virtualization packet to a network device other than the virtual network element by using the remote network element port corresponding to the virtualization packet.
