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

 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 →

Work in Progress

 Two new groups established May

2013:

– Narrative group Exec Action Team → – Architecture group:

Jim Williams (I2) and EJB co-chairing

 Deadline:

– Early December 2013 Interim Paper →

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 →

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
…

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)

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
