GENI has compute and networking resources across the United States that experimenters can use to set up network topologies and to program them. In addition, GENI federates with other US and international testbeds the United States and outside, giving GENI users the ability to include in their slices resources from these testbeds.

 Status of GENI Resources |
An ExoGENI rack. Click on the figure to learn more about GENI racks.
These are the most widely deployed GENI compute resources. Each rack is a small cloud that makes virtual and bare machines available to experimenters. All GENI Racks have IP connectivity through the commodity Internet for control and management. They also connect on layer 2 to the GENI backbone network (national and regional research and education networks) that provides the programmable data plane.
here are three kinds of GENI Racks: InstaGENI from HP/University of Utah, ExoGENI from IBM/Cisco/RENCI and OpenGENI from Dell/Clemson.
GENI Wireless nodes.
GENI wireless nodes. Click on the figure for a diagram showing how they connect to base stations
These “yellow nodes” are available at sites with GENI 4G wireless basestations. Experimenter software on these nodes can configure base stations, send/receive traffic and make measurements.
GENI wireless sites also have Android handsets available for use in experiments.
Federated testbeds
Emulab, PlanetLab and iMinds testbeds. Click on the figure for a list of testbeds federated with GENI.
A number of US and international testbeds are federated with GENI and provide resources to GENI experimenters. Experiments can include resources from these testbeds in addition to those from GENI.
Internal connectivity of an OpenGENI rack. Click on the figure for information on networking and computing on GENI racks.
GENI racks have multiple worker nodes that are connected by an OpenFlow switch. Experimenters can set up topologies using compute and networking resources that live entirely within a rack. They can use OpenFlow to control traffic on links that pass through the rack switch.
National network backbone
Internet2 Advanced Layer 2 Service.
Internet2 provides backbone connectivity for GENI through its Advanced Layer 2 Service (AL2S). In addition to providing backbone connectivity, experimenters can provide OpenFlow controllers for the AL2S switches
Regional Research and Education (R&E) Networks
Map of LEARN, the Texas Regional R&E network. Click on the figure for a list of regional networks that are a part of GENI
Regional R&E networks connect GENI racks and other resources with Layer 2 connectivity to the Internet2 AL2S backbone network. Some regional networks host GENI racks and OpenFlow switches.
