    3333=== Layer 2 Tunneling ===
    34 QinQ allows campuses to tunnel an agreed upon VLAN ID through an intermediate network. The intermediate network can then use a different VLAN ID to control the topology. The regional or backbone networks may use Provider Backbone Bridging in addition to QinQ. Other layer 2 tunnel alternatives may be available through a regional network, such as MPLS.  Both Internet2 and NLR GENI core networks support QinQ tunneling, as do most regional research networks.

    3636=== Direct Fiber Connection ===
    37 Internet2 and NLR can also support direct fiber connections to their equipment at some GENI locations, which generally allows for higher layer 2 throughput and more flexibility for experimenters.  For example, campuses may arrange for direct fiber connections to Internet2 or NLR’s OpenFlow core networks.  Dedicated fiber connections generally have higher cost and lead times than other network options.
