Transcript TEN-155: Europe moves into the fast lane II

GÉANT: deployment and development of
Networking for European Research

GÉANT
European Gbps Network for Research
• 10 Gbps in 8 locations, 9 circuits
• 2.5 Gbps in 7 locations, 12 circuits
• 3 providers: Colt, DeTe, Telia
• Connects 31 NRENs
• Connectivity to N.A (3x2.5Gbps)

European Coverage for
wavelengths
• Easy in UK, FR, NL, DE, BE
• Accessible in AT, CH, ES, IT, CZ, HU, SK, PL, SE
• Too difficult in GR, PT, SI
• Virtually impossible elsewhere
• Europe is still not uniform! Especially in the
access
Technology
• Nortel, Lucent DWDM equipment
• 10 Gbps wavelengths are presented as SDH (i.e
POS interface on routers)
• 2,5Gbps are a mix of wavelengths and
“transparent” SDH services (provide clocking),
presented as SDH
GÉANT Development
• Multicast, ipv6, monitoring
• Support for User groups
• Premium IP (MOICANE, LONG, AQUILA…)
• MPLS techniques for support of testbeds (6NET,
ATRIUM, DATATAG)
• How can “pure optical networking” help?
• beyond 10Gbps to hundreds of Gbps
• 40Gbps ?
• Multiple wavelengths ?
Beyond 10Gbps
• 40Gbps in pipeline on DWDM equipment
• Router equipment readiness unclear
• Business case for carriers unclear
• Not only 40Gbps, but higher utilisation of
spectrum on fibres
• more wavelengths (up to 160)
• at various capacities (2.5, 10, 40 Gbps)
• Goal is to have access to 100+Gbps by 2004
What next ?
• Manage backbone resources
• how do we handle more wavelengths, optimise routing
• Manage user requests
• circuit switched vs. packet switched
• granularity - how do we handle XMbps out of 10Gbps?
• how to cope with reduced EU coverage for user requests
(grids)?
• What are the network components that will help us
do this?
Thank You !
