Evolution From GN1 to GN2
  • Build on the GÉANT Pan-European IP RE network
    An international success story
  • Deploy GÉANT2, a new generation HYBRID Network
    backbone IP(v6) switched end-to-end provision
    across interconnected networks (over DARK FIBER
    among 15 countries growing)
  • Ubiquitous global services to users across NRENs
    beyond via IPv6 and manageable e2e lower layer
    paths (e.g. WAN GigEthernet Light-path
    switching)
  • Gaining improved understanding of user needs
    Grids/eScience
  • End-user support, user access to e2e
    provisioning, AAA, collaborative services,
    roaming
  • User basis Universities, Research Centers,
    Schools (?), eScience Initiatives (Grids),
    Digital Libraries

The GÉANT2 Optical Network
6
Revolution Global Hybrid Networking
  • The Internet enabled the ubiquitous global
    networked community based on IP services the
    Web
  • The Next Generation Hybrid Network will enable
    the global knowledge based society by providing
    advanced collaborative platforms via hybrid IPv6
    Manageable Layer 1-2 (Ethernet Light-path
    switching over Dark Fiber) Services
  • RE HPCN and Grid requirements motivated the
    design and deployment of GÉANT2 as a hybrid,
    Dark-Fibre (DF) network
  • GÉANT2 offers this new environment to European
    Researchers Educators and paves the way for
    global, ubiquitous advanced networking services
    (cyber-services)
  • The NREN - Grid /HPC communities test develop -
    tailor and deploy network-based services
    applications Collaborative platforms, security,
    AAA, roaming

GÉANT2 Global Connectivity
8
Global Connectivity Policy in GÉANT Distributed
European Access (DEA)
  • DEA concept dates back to the full IP world (ca.
    2000)
  • Homing to GÉANT PoPs with redundant Gigabit
    access
  • Alternatives
  • Interconnect via host NREN GÉANT PoPs (e.g.
    Austria - Ukraine)
  • Establish separate regional PoPs (e.g.
    EumedConnect)
  • Procure regional network anchored in GEANT NREN
    PoPs (e.g. SEEREN)
  • Cross-border direct links (e.g. Serbia Hungary
    Cross Border Fiber)
  • Satellite links (e.g. Turkey lt 2004)
  • Cost sharing issues
  • Accepted Usage Policies (AUPs)

9
Global Connectivity Policy in GÉANT2 (GN2 - SA4)
  • DEA needs redefinition in new HYBRID world (L1,
    L2 e2e switching L3 IP routing)
  • Global Connectivity Committee set-up by the NREN
    PC consisting of
  • David Foster (CERN), Vasilis Maglaris (NREN PC),
    Kees Neggers (SURFNET), Esther Robles (RedIRIS),
    Enzo Valente (GARR), Dany Vandromme (RENATER),
    Martin Wilhelm (DFN)
  • Goal Enable all scientists educators
    students (pupils?) with quality access to the
    Global Information Society
  • Via ubiquitous high speed, reliable IP routed
    internetworking amongst RE Networks world-wide
  • Complemented by the provision of e2e switched
    Gigabit connections to power users (for
    international eScience - Grid experiments, e.g.
    LCG)
  • Bridge the digital divides within Europe and
    globally
  • Assist formation of viable NRENs, if not existing
  • Assist formation of Regional Networks if
    necessary (e.g. EumedConnect)
  • Join forces with non-European NRENs (e.g.
    Internet2) to strengthen impact
  • Seek assistance from EU (DG INFSO, EuropeAid,
    Regional Funds), EIB, UNESCO ...

10
Evolution NREN Hot Potatoes
  • Assess NREN GÉANT requirements technology
    trends over the next 10 - 20 years (foresight)
  • Test deploy bleeding edge technologies (e.g.
    nx40 Gbps over DF) and adopt novel business
    models (e.g. DF ownership Cross-Border Fibre
    provisioning by neighbouring NRENs)
  • Coordinate between Next Generation Networking
    High Performance Computing towards a Global Open
    HPCN Architecture
  • Test deploy GÉANT - wide Security Monitoring
    (prerequisite for eScience / Grids, eSchools,
    Digital Libraries, eGovernment, eHealth )
  • Establish virtual collaborative environments
    (e.g. VRVS, Access Grid)
  • Enhance global connectivity (USA, Canada, China,
    Japan, Korea, South Africa, Latin America,
    SEEREN, EUMED North Africa, West Africa, India,
    )
  • Help to overcome digital divides
  • Promote NRENs GÉANT GÉANT2 as a European
    success story to End-Users National / EU
    Decision Makers
  • while at the same time
  • Keep-up the good work and meet new challenges in
    the eScience world (deploy hybrid optical
    technologies, provide e2e L1/L2 connectivity,
    update cost sharing models, test new business
    models )
  • Not a mission impossible!

Lessons in bridging Digital Divides - 1
  • Digital Divides encountered in European NRENs
  • Within EU nations (North South, Cities Rural
    Areas, IT knowledgeable IT novices within a
    Campus)
  • Outside the EU EumedConnect (North Africa),
    SEEREN (South East Europe) .
  • Regions with expensive telecom infrastructure
    (quasi-monopoly TELCOs)
  • Hard to lease fiber (dark of lit)
  • Political instabilities
  • But
  • Highly qualified human potential in the RE
    sector, especially in ICT ? brain draining effect
  • Acute needs for e-participation, e-learning

12
Lessons in bridging Digital Divides - 2
  • Positive attitude
  • Do not settle for expensive short term solutions,
    if possible (e.g. satellites)
  • Try to leap-frog in advanced solutions. Examples
  • Balkan dark fiber initiatives for NRENs
  • NRENs of new EU member states (Poland, Czech
    Republic .) are champions of optical
    technologies
  • Use wireless links (license free?) to complement
    fiber optic feeds (WiMAX)
  • Aggregate funds EU, National, International
    Assistance bodies
  • Respect national priorities 1 NREN per country,
    AUPs
  • Consider Regional Aggregations if cultural and
    economic factors allow (aka. SEEREN,
    EumedConnect, towards a NORDUNet US Regional
    PoPs paradigm)
  • Develop Federation amongst NRENs and/or Regional
    RE Networks, well connected and managed,
    partially funded by constituent NRENs (aka.
    GEANT, RedCLARA) - Governance?
  • Be integral part of the Global RE Networking
    Community
  • LESSONS APPLICABLE IN AFRICA?
  • YES, a not so distant dream
