Purpose

Provide information about the evolution of the GNA

Explain how the GNA will move forward

Solicit your input and participation


What started GNA?

Problem Statement

Limited global NREN strategy coordination

Initiative by Internet2(USA), CERNET(China), NORDUnet(Nordics) and

Janet(UK)

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

model currently ~15 x CEOs part of CEO forum

Goal: Seamless global service delivery for users in R&E


What is GNA?

GNA 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)

James Williams (Internet2)

GNA Architecture working group formed with participation from several

R&E networks

Co-chairs: Jim Williams and Erik-Jan Bos

Delivered paper for Dec 2013 CEO forum meeting. Work on the paper

carried out by network architects from AARNet, CERNET, DANTE,

ESnet, Internet2, Janet, NORDUnet, RedCLARA, RNP and SURFnet

GNA Approach


GNAR&E Intercontinental Bandwidth - Sept 2013


GNA Approach

Greenfield approach but leveraging:

Existing R&E Infrastructure and their BCPs

Existing and planned subsea cables

Research and big science installation as hubs

Yielding

Powerful network substrates based on:

– Fat Pipes

– Global R&E Exchange points

– Provisioning and operational tools & systems


GNA – Arch group direction

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

Looking at the infrastructure and research trends, not just at

technologies

Develop the three sub-groups (Ops, Tech and Services)

Use ANA-100G as a pathfinder project

Coordinating funding in smart ways via EAT


GNA – Communicate and Consult

Test ideas with broader audience

Solicit further input & guidance at international events:

APAN, Internet2 Global Summit, TERENA Network Architects

Workshops, GLIF, TNC, etc


GNA Implementation

No big bang scenario

Slow start (low hanging fruit)

Gradual phasing in (align spending for intercontinental bandwidth)

Substrate and Overlay Services: Progressive automation

First: Manual (horizon: 5 years)

Later: automatic (horizon: 10 years)


GNA Artist’s impression


ANA-100G

GNA Pathfinder


GNA Evolution


GNA Next Steps

The GNA or GNet is about defining a framework for NREN and

Exchange point to participate in global network

Gnet will be a collaboration or federation of existing networks/exchange

points

It is set of rules that organisation agree to follow to participate


GNA –Ops & Security

Federated Operations and Security Model

Develop a data/health template to be applied to all physical devices and

services

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

participation


GNA – Services

Overlay networks e.g. LHCONE

Point-to-Point Circuits

Dynamic circuits

Multi-point VLANs


GNA – Technology and Topology

The exchange point must be open and shouldn't impose any AUP

Must support the functionality needed to support the GNA network

services

VLAN Translation, etc

Must connect to at least one other GXP with link which doesn't impose

any AUP.


GNA Substrate & Overlay Networks

Examples of

overlay networks

over GNA:

IP Interconnect

Global Peering

Service

P2P Circuit

Service

OPNs

ONEs

Testbeds
