Outline
GENI: Global Environment for Network Innovation
• GENI funding
– GENI Spiral-1 & Spiral-2 (2008-2012): Measurements, Measurements
(with Infinera DTN), Integration with LEARN through ORCA
– GENI Spiral-3 (TBA): GENI Rack Deployment on LEARN
• Future Plans
– GENI Rack Deployments
– University of Houston-LEARN DYNES
• Follow-up Workshop on GENI and Other Network Research on
LEARN
UH GENI (2008 – 2012)
UH Spiral-1 and Spiral-2 GENI Funding
• Spiral-1:
– Measurements
available on network
equipment (embedded
or internal
measurements)
– External measurements
– Physical layer emphasis
• Spiral-2:
– LEARN-Infinera DTN
agreement:
measurement handler
software
– Integration of LEARN
as a RON into GENI
substrate with VLAN
offerings - ORCA
Introduction to GENI ORCA
ORCA (Open Resource Control Architecture) Control Framework
• Control/configure network elements (switches,
routers, optical boxes) through SSH connections
– Resource Broker, Clearinghouse
– Measurement and Computational Services as Resources
• More on this coming up by Ilia Baldine from RENCI…
• ORCA handlers for ION interfaces will be available
summer’11
GENI-LEARN Integration
Phases of Deployment
• GEC9: An emulation network with Cisco 3400s
– QinQ demonstration
– Handler testing on emulation network
• Early Jan’11: Determination of VLAN assignments
and translation points
• Feb’11: Designation of campus and RON connection
points
• By GEC10: Ongoing deployment sequence: UH, Rice,
TAMU, and UT-Austin

VLAN Assignments
Translation Points and Interfaces
• NLR – LEARN: VLANs from NLR are mapped to
reserved range of VLANs on LEARN
• SETG (Southeast Gigapop) – LEARN: SETG
resources take VLANs from LEARN as a
distribution point to other institutions
• Institutions – SETG: Each institution has a pair
of VLAN id’s for data and management

GENI Spiral-3
GENI Racks Deployment on LEARN
• Participated in GENI racks (network
equipment and high-speed computation
resources) proposal with ORCA team at:
– TAMU
– Rice
– UH
• Requested funds to pay for LEARN bandwidth
• Awards to be announced by mid-2011
Future Outlook
LEARN and GENI
• LEARN, UH and Rice have been funded by the
Internet2 DYNES initiative (TAMU and others might
be added)
• ORCA-ION handlers – possible extension and added
flexibility of connections
• Performance measurements as resources on LEARN
• Follow-up workshop with more involvement of the
Texas-based high performance computing centers
and potential researchers and experimenters
