Moving Towards aGLOBAL NETWORK ARCHITECTURE

GNA

2

Refining and Evolving the Global Network Architecture

GNA

Vision: To describe an inclusive, collaborative Next Gen intercontinental R&E network infrastructure with a 5 to 10 year horizon

Initial document by • Xing Li (CERNET) • James Williams (Internet2)

So what started work on the GNA?

Global REN CEO Forum Initiative:Internet2CERNETNORDUnet Janet

Goal: Seamless global ”services” delivery for users in R&E

Limited global NREN strategy coordination existed prior to 2012

Initiative by Internet2, CERNET, NORDUnet and Janet to organize strategic dialogue

Initial participant selection based on R&E stats, smaller group, ”G20” model

Addressing Common Challenges

GNA Evolution – not a new network

5

The GNA and the Global Network (GNet) are less about a physical network and more about defining a framework for national networks and exchange points to participate in a global network.

The GNet will be a collaboration or federation of existing networks/exchange points. The GNA will be the framework or set of rules that organizations agree to follow to participate in the GNet.

GNA – Architecture Group Direction

High-level, focused on long-term goals (5-10 yr)

Looking at infrastructure and research trends, not just at technologies

Develop three areas (Operations + Security; Technology +Topology; Services)

Use ANA-100G as a pathfinder project

Coordinating funding in smart ways via EAT

GNA – infrastructure approach

Greenfield approach... but leveraging:

Existing and planned subsea cables

Research and big science installations

Advanced R&E networks & their BCPs Yielding...

Powerful network substrate:

Overlay networks

fat pipes GREX (Global R&E eXchange) Provisioning and operational tools & systems

GNA – implementation

Slow start (low hanging fruit first)

Gradual phasing in

No-one left behind – national, regional, global consultation

Physical infrastructure: no big bang scenario

Transport substrate: progressive automation

First: Manual (horizon: 5 years) – e.g. GN3plus SA2+GLIF+SDN work

important

Later: Automatic (horizon: 10 years)

Engage the community

10

Engage other networking efforts:

Involve other efforts and ideas such as the developing ESnet international network, the NSF IREN planning and the EC Horizon 2020 efforts. And, of course, developments in the ME (eg. Fujairah AGE-OX, etc.)

Formally engage the community:At CANSAt the Internet2 Global SummitAt the TNC meetingAt APANAt SIG meetings….

How to participate!!!

13

We need your participation and feedback. The framework we are developing will only be as good as the intellectual input creating it.

For the GNA: You need a strong technical area of expertise (senior network architects) You need to be able to commit to working on GNA activities, attending GNA video conferences and a yearly(?) GNA face-to-face. You need a commitment of your time and financial support from your CEO. You need agreement from your NREN, as you will be representing your NREN.
