    207211Details?
    208212How?
     213
     214
     215
     216== 4.  Configuration of VLAN Connections ==
     217
     218
     219=== 4.1 Ordering of VLAN Connections ==
     220
     221Ordering of VLAN connections is likely to proceed from the backbone out to the endpoints:
     222
     223a)  In a demo on 7/7/09, the ORCA/BEN project:
     224•       Used Sherpa to pre-configure VLANs through NLR
     225•       Pre-assigned VLANs through the Duke campus network
     226•       And then mapped VLAN tags near the endpoint nodes.
     227See http://groups.geni.net/geni/attachment/wiki/ORCABEN/071509c%20%20ORCA_BEN%20demo.pdf , Figures 6-2, 6-3 and 6-4.
     228
     229b)  In a suggested approach to connectivity specification at http://groups.geni.net/syseng/wiki/RspecConnectivity , it is suggested that:  “we give the backbone priority in selecting a network's VLAN ID and aggregates must map the ID within their local network by whatever means is most convenient for them. This way, the experimenter need only know what backbone the aggregate is connected to, and can design the network from there.”
     230
     231
     232=== 4.2 Static or Dynamic Connections Through Backbone ==
     233
     234a)  ProtoGENI (Emulab) uses pre-configured (static) VLANs on Internet2 GENI “wave”, between certain Internet2 Wave System nodes.   
     235See http://www.internet2.edu/waveco/ and http://www.protogeni.net/trac/protogeni/wiki/BackboneNode
     236
     237b)  ORCA/BEN project pre-configured (static) VLANs using NLR FrameNet service.  See http://groups.geni.net/geni/attachment/wiki/ORCABEN/071509c%20%20ORCA_BEN%20demo.pdf , Figures 6-2, 6-3 and 6-4.
     238
     239These were provisioned using Sherpa service. 
     240
     241ORCA plans to provide an interface into the Sherpa GCI by 2/1/10, which would allow VLANs in NLR to be dynamically setup.
     242
     243Dynamic setup would allow additional flexibility, with some complications.
     244
     245
     246=== 4.3 Connections Between Backbones ===
     247
     248 The iGENI (Starlight) crossconnect includes the Starlight L2 crossconnect service in Chicago, which connects to multiple backbone networks, both domestic and international, including NLR and Internet2.
     249
     250See http://www.startap.net/starlight/ENGINEERING/SL-TransLight_5.06.pdf
     251
     252See http://www.startap.net/starlight/NETWORKS/
     253
     254The Starlight service should be able to bridge connections between multiple backbone networks, allowing access to distant testbeds.  It may be able to bridge VLANs between NLR and Internet2, if allowed.
