GÉANT
• It’s the big fella’ !
• GÉANT:
– Gigabit speed
– Guaranteed bandwidth
– Geography expansion
– Global connectivity

TEN-155 Service
• Basic IP service
– 20 NRENs, 1 “RREN” covering 25 countries
– access capacities from 10 to 622 Mbps
• MBS (Managed Bandwidth Service)
– Guaranteed capacity
– ATM-based
– VPN capability: testing of new technologies
(native multicast, diffserv, MPLS, IPv6)
GÉANT – A Giant Step - [email protected] (4/16)
GÉANT - Targets
• Gigabit speed:
– Initial start: 2.5 Gbps in 8 locations in 2001
– Tens (or hundreds) of Gbps within 4 years
• Guaranteed services:
– Improved resilience
– End-to-end QoS
• Geographical coverage expanded
– All EU countries and accession states …
• ... connectivity to other global regions
– European Distributed Access (EDA)

GÉANT – Organisation
• NREN Consortium
– Long-standing
– Open-ended consortium
– NREN Policy Group: pricing and policy
• DANTE’s role:
– Coordinating Partner in the project
– Delegated responsibility for service development/
innovation, implementation and operation of the
network

GÉANT – an EC funded project
• Four year project with 25 NRENs (=24+1)
– Reaching 3000 to 4000 organisations!
• Project effective 1 November 2000
• 80 Meuro committed by EC
• Chance of further EDA funding
eg for US, Asia/Pacific, South America

GÉANT Services
• Production IP service
– including connection to non-EU research networks
•
•
•
•
•
Native multicast
Premium IP service
Guaranteed capacity
Virtual private networks
New services
– IPv6
– support for “disruptive” testing
(alternative to ATM CBR service)

GÉANT Hurdles
• Equipment
– at leading edge of what suppliers offer
» Optical transmission
» IP routers
– QoS support - nothing (yet) to replace ATM
• The dinosaurs: monopolistic remains
– changed by 1998 liberalisation in EU
– still applies in some countries
• Cost

GÉANT Procurement
• TEN-155 continues until 30 November 2001
• Tender response
– 44 tenders received (29 September 2000)
– 16 for pan-European connectivity
» Most offers based on wavelengths
– Over 4,000 circuits on offer!
– Targets will be met; 10Gbps is available

GÉANT Technology
• 2.5/10 Gbps as single wavelengths
– with SDH framing
– no access to optical level / (dark) fibre
» TEN-155 aggregate circuit length = 22,000 km
• IPv4 + IPv6 test network
• MPLS + diffserv support for QoS and VPN
GÉANT – A Giant Step - [email protected] (13/16)
Stepping to 10Gbps?
• Cost vs capacity
– 10Gbps in 8 countries …
» quadruples capacity
» adds less than 10% to cost
– Pushing 2.5Gbps as far as possible
• Technical

Simpler upgrade path
Technology risks

Outstanding Issues
• Service will be diverse (wavelengths and SDH)
• Guaranteed bandwidth and VPN capability needs
further development . . .
• . . . as does management of end-to-end capability
• Cooperation of NREN, MAN and campus network
operators is needed
GÉANT – A Giant Step - [email protected] (15/16)
Summary
• 10 Gbps now!
• Wavelength networks
– National and International
• Better geographical coverage
• Progress on global connectivity
• Challenging the vendors
• QoS/VPN will need your help!
