A multiplex method of a virtual local area network (VLAN) switching (VS) tunnel includes the following steps. An ingress edge node of the VS tunnel maps a received customer data unit onto one virtual channel (VC) borne by the VS tunnel, and encapsulates the customer data unit into a VS tunnel Ethernet frame including a VS tag, a VC tag, and the customer data unit. The VC tag identifies the different VCs borne by the VS tunnel. An intermediate node of the VS tunnel switches the VS tunnel Ethernet frame according to the VS tag, and transports the customer data unit and the VC tag transparently in the VS tunnel. An egress edge node of the VS tunnel terminates the VS tunnel and the VC, recovers the customer data unit, and forwards the data according to the VC tag.
