2 Nordic Infrastructure for Research & Education Developments on Global Network Architecture for Research and Education - Erik-Jan Bos (per videolink from The Netherlands) Please NOTE: This is Work In Progress! 2nd TERENA Network Architects Workshop Praha, CZ November 13-14, 2013

3 So what started GNA work? No global NREN strategy coordination existed prior to 2012 Initiative by Internet2, CERNET, NORDUnet and Janet to organize strategic dialogue Goal: Seamless global service delivery for users in R&E Participants selection based on R&E stats, smaller group G20 CEO Forum

4 Global Network Architecture GNA: One of the four CEO Forum's Challenges, est. Geneva, Sep 2012 Vision: To describe an inclusive, collaborative Next Gen intercontinental R&E network infra with a 5 to 10 year horizon Initial document by Xing Li (CERNET) and Jim Williams (Internet2) GNA work

6 Work in Progress Two new groups established May 2013: Narrative group Exec Action Team Architecture group: Deadline: Jim Williams (I2) and EJB co-chairing Early December 2013 Interim Paper

7 GNA approach Green-field approach, leveraging: Existing and planned subsea cables Research and science installations Advanced R&E Networks + their BCPs Yielding: Powerful network substrate: Fat pipes (fiber or spectrum) Open Exchange Points Overlay networks Migration from current GNA

8 Transition: Current R&E bw Source: Mian Usman (DANTE)

9 GNA substrate (1) The transport Substrate: The basis for overlay networks Possible examples include: IP Routed interconnect Global peering service Point-to-point circuit service OPNs ONEs Testbeds Demo networks

10 GNA substrate (2) No big bang scenario: Slow start (low hanging fruit first) Gradual phasing in No-one left behind Steering the transport Substrate: First: Manual (horizon: 5 years) e.g. SA2 work important Later: Automatic (horizon: 10 years)

11 ANA-100G: GNA Pathfinder

12 GNA Next Steps Continue with the Architecture group: High-level, focused on long-term goals (5-10 yr) Looking at infrastructure and research trends, not just at technologies Coordinating funding in smart ways Exposing the GNA ideas to a broader audience, e.g. at GLIF Tech & the TERENA Network Architects Workshop: To test ideas with broader audience To solicit input
