    1010QinQ can be used to "tunnel" a particular VLAN of a "customer" network through a "service" network. This is a very important concept in GENI to allow multiple "customer" VLANS to be interconnected through the VLANS of regional service providers.

    1414In the image above VLAN A and VLAN B are two VLANs that span between "Network 1" and "Network 2". These networks can be at two separate sites.  VLANs A & B are tunneled through the "Intermediate network" using VLAN Q. This allows the customer network VLAN usage to be independent of the Intermediate Network while still allowing the customer VLAN traffic to transverse the intermediate network. The Intermediate Network has a "separate VLAN ID space" than the two other network sites. VLAN X could be the same VLAN ID as either VLAN A or VLAN B without any collision.
