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