Provide

information about the creation/evolution of the GNA.

Explain how the

GNA will move forward.

So what started work on the GNA?

Global NREN

CEO Forum

Initiative:

Internet2

CERNET

NORDUnet

Janet

15 x CEOs.

Based on

”G20” model

Goal:

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

l  Limited/informal global NREN strategy coordination existed prior to 2012

l  Initiative by Internet2, CERNET, NORDUnet and Janet to organize strategic

dialogue

GNA –

Architecture Group Direction

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

Ø  Looking at infrastructure and research trends, not just at technologies

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

Ø  Use ANA-100G as a pathfinder project

GNA

15

GNA –

Communicate and consult broadly

Ø  e.g. APAN; I2 Global Summit; TERENA Network Architects

Workshops

Ø  TNC2014 May 2014 <DW>

Ø  APAN38 August 2014 <JGW>

Ø  CANS September 2014 <JGW>

Ø  GLIF Queenstown, Sept-Oct 2014

Test ideas with broader audience

Engage the community

16

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, the Chinese Internet development efforts.

Formally engage the community:

At CANS

At the Internet2 Global Summit

At the TNC meeting

At APAN

GNA – infrastructure approach

l 

Greenfield approach...

but

leveraging

:

Ø 

Existing and planned subsea cables

Ø 

Research and big science installations

Ø 

Advanced R&E networks & their BCPs

l 

Yielding...

Ø 

Powerful network substrate:

Ø 

Overlay networks

Ø  fat pipes

Ø  GREX (Global R&E eXchange)

GNA

18

GNA – implementation

Ø  Slow start (low hanging fruit first)

Ø  Gradual phasing in

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

Physical infrastructure: no big bang scenario

Transport substrate: progressive automation

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

ANA-100G : GNA pathfinder – production ready Q4 2014

WIX

21

The ANA-100G is interesting…but how does

that apply to CANS (US-China)??

CERNET/CSTNET participation in GNA

10G

1.  CERNET/CSTNET have internal 100G/10G backbones

2.  CERNET/CSTNET IX in BJ, HK and LA will participate in GNA via current 10G links

GNA Evolution – not a new network

24

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.

Some examples from Ops+Security

25

Federated Operations/Security Model Guiding Concepts

Develop a data/health template (management functions) to be

applied to all physical devices and services

Be minimally invasive. Strive for uniformity, but not at the expense

of participation

26

Some of the functions may have to be globally

organized, and made transparent to all, to create the

basis for a solid high-quality service. Other functions

just need to be organized locally, as they do not have a

global impact.

The following slide represents a picture of how this

might be structured.

How to participate!!!

29

We need your participation. The framework we are developing will only be

as good as the intellectual input creating it.

The GNA is a technical group. The EAT is a policy group.

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.

How to participate!!!

I am happy to answer questions about participation and to discuss

further the details and requirements. Stop me in the hallway or just

drop me an e-mail.
