2. 23 September 2015 Pan-Continental Perspective: Key Issues seen by Internet2 Guy Almes almes@internet2.edu Heather Boyles heather@internet2.edu Steve Corbató corbato@internet2.edu Guy Almes almes@internet2.edu Heather Boyles heather@internet2.edu Steve Corbató corbato@internet2.edu

3. 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.

4. 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)

5. 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

6. Optical network project differentiation Distance scale (km) ExamplesEquipment 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 Regional/ National  500 TeraGrid, NG Abilene, PLR Add OEO regenerators & O&M $’s

7. 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

8. 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
