• 1. NREN Constituency
• NRENs started with universities and

research labs as main constituency

• For many NRENs this has been step-by-step

extended to schools, museums and other educational institutions

• Idea: A good and content-wise rich network

is good for other educational sectors as well

• However: The main NREN constituency

will be defined by the universities

Seite 4

• 2. NREN users / adv. applications
• Mainstream for a couple of years will be the

provision of the Internet service through the NREN for all users in the constituency

• A couple of specific groups from research

disciplines will however have to run advanced applications due to their demanding requirements or innovative approaches

• This will drive NREN developments in the

next years

GÉANT2 - “Big” Users (Examples)

• LHC
• 11 Tier1 sites

» 7 in Europe » 4 outside Europe (US, Canada and Taiwan)

• DEISA
• EVN (European VLBI Network)
• 15 sites

» 5 already connected

• MUPBED

• 3. Technology development
• (a) IP networks (NRENs plus Geant2) have

to be adapted to still growing needs

• (b) Optical technology is being introduced

NOW (in most NRENs and on the European level as well)

• Consequence 1: Bandwidth will no longer

be a scarce resource

• Consequence 2: VPNs are economically /

technically feasible solutions to special requirements such as Grid applications

GÉANT today - Services

• Best Effort IPv4/IPv6
• Multicast IPv4/IPv6
• Premium IP
• Less than Best Effort IP
• MPLS
• L2-VPN
• Martini L2-circuits, Juniper CCC

Seite 9

GÉANT2 - Service Plans

• Versatility to better facilitate E2E services
• Continue to provide quality IP transit services
• Tune existing IP service platform

– Optimise platform – Enhance resilience

• Offer “Enhanced MBS” [or “lightpath” service]

– “Wavelength” services for big users – Sub-wavelength services as well – Develop automated (“on demand”) provisioning and advance scheduling – Up to 10G

• Endeavour to be prepared to implement 40G

services

• 4. Basic building block: dark fibre
• Dark fibre is the basic element for any

bandwidth provision

• Technology for lighting the fibre is available

at reasonable prices

• If scenarios like LHC / VLBI /... are assumed

to contribute more and more to the networking demands then the consequence for NRENs and Geant-x (x>1) is clear: Get as much fibre as financially affordable

Cross-Border Fibre

• Within the lifetime of Geant2:

– # fibre NRENs will have increased – dense web of fibre within NRENs and across Europe, perhaps small links missing – new technical and economic opportunities

• ==> Geant2 must be technically and
• rganisational adapted to this evolving

structure

• Cross-border link should be seen as

complementary to traditional links

Seite 19

• 5. Policy Framework
• Most existing policy concepts are adapted to

Internet technology / economy

• New technical options like the IP-PoP

reallocation option need to be mapped into new policies on the network

• Cost distribution scheme
• EDA (European Data Exchange) ...

New policy concepts have to be develo- ped - however this will be relatively slow and more a complement rather than a revolution

Seite 20

Summary and Outlook (1)

• Constituency

Universities will remain to be the main NREN constituency for the next time

• User Community

„Big“ user communities will drive NREN developments in the next years

• Technology

Optical VPNs are economically / techni- cally feasible alternatives to special re- quirements such as Grid applications

Seite 21

Summary and Outlook (2)

• Dark Fibre as essential building block

Get as much fibre as financially affordable

• Policy Framework

New policy concepts have to be developed - however they will be complements rather than revolutionary

• issues. Basically cooperation oriented.
