Where Internet2 is coming from
University-led
Partnership model• Abilene built & operated in partnership with Qwest, Cisco, Juniper,
Indiana University
Hierarchical network model• International – GTRN?• National – Abilene• State/Regional – CENIC/CALREN2, SURA/SoX• Metro/Campus
Gov’t Mission and University Split• ESnet, NREN, DREN – gov’t labs• Somewhat blurred: several gov’t labs connected to Abilene
– Reflects close ties between gov’t labs and U.S. univs.

Technical Outlook
Goal: support advanced/leading-edge/high-performance applications of the research and education community
Approach is technical direction that has pragmatic benefit to applications
• Illustration: Internet2 Quality of Service Work–Premium Service experience
• Raw HDTV/IP – single UDP flow of 1.5 Gbps (Seattle Washington DC over Abilene)

Technical/Economic
Unique window in time for fiber assets• Cause: fiber glut, bankruptcies and telcos in distress • Within a year, opportunity on national scale closes?• Hedge against a regression to ‘bad old days’ of monopolies
Technically, getting fiber means controlling the network down to layer 1 (0?)
• Would allow deployment of different wavelengths for differentiated networks (high perf advanced services, network research, more general EDU access)
• Path to doing optical switching when it makes sense
Technically and economically, we see this emerging chronologically from bottom of hierarchy to top

Optical network project differentiation
Distance scale (km)
Examples Equipment
Metro < 60
UW(SEA),
USC/ISI(LA)
Dark fiber & end terminals
State/
Regional
< 500 (LH)
(ULH: <2000)
I-WIRE (IL),
CENIC ONI,
I-LIGHT (IN)
Add OO
amplifiers
Extended

National Fiber Facility
Research and education community investment in national-scale fiber assets
• Discussions among a number of partners in US ongoing– “National Light Rail” – being led by members of Internet2
community – CENIC, the Pacific NorthWest Gigapop and other partners
– SURA – focused on specific bankruptcy opportunity
– UCAID is a participant in both efforts
• Once the national fiber footprint (~15,000 km) is obtained, significant investments in ULH optronics and ongoing maintenance/operations are required

Economic/Political Issues
Current Abilene infrastructure funded by universities
• With important initial seed money from NSF to universities
Expect to follow partnership model to extent possible for national fiber facility
• Corporate partnership essential for ongoing maintenance on fiber plant & co-location and next generation optronics
• Interestingly, optronics vendors now are becoming aware of the enterprise (non-carrier) market for their WAN gear
US government support critical• Cyber Infrastructure report from NSF
