Milestone CMU Lab: integration of node-CMU and CMU-Utah tunnels

Task 4: Data plane integration with ProtoGENI. Be able to run experiments that share packets between ProtoGENI central (for our purposes, the main Emulab cluster) and the wireless testbeds. Use Internet2 VLAN support to get packets from Emulab to our protoGENI control node (if feasible). Use IP-in-IP tunneling to get packets from the CMU control node to HomeNet nodes (these nodes, being residential, will not have access to Internet2 VLANs). Note this is ONLY the data-plane tunneling mechanisms, NOT the control mechanisms needed to establish it.

4a: Get CMU ProtoGENI node on I2 VLAN (2mo)

4b: Tunneling packets from Utah to CMU (depends on 3a): (4mo)

4c: IP-in-IP encap from CMU-Control to Homenet nodes (depends on node management): (6mo)

Integration of 4b and 4c: (7mo)

Linking Homenet nodes to experiments running elsewhere is a manual process documented at ​http://moo.cmcl.cs.cmu.edu/wiki/index.php/Homenet_Connectivity.
