RD Platforms

• NRENs - GÉANT2 provide cost effective e2e
  switched light path connectivity within the
  Dark Fiber Cloud (DWDM footprint)
• Global IPv4 IPv6 coverage and Hybrid
  networking services
• Network management, resiliency support
• e-Science (GRID) Virtual Organizations obtain,
  production quality hybrid networking, beyond
  leasing individual circuits, wave-lengths or dark
  fibers
• e-Infrastructures as equalizers, reduce the
  DIGITAL DIVIDES in Europe globally Big
  Science affordable via virtual e-Science
• NRENs - GÉANT2 stimulate Network Research
  enable novel concept evaluation - emulations in
  a global production environment via
  virtualization of facilities services

  model of cross-border fiber NREN arrangements
  (especially for circuit-switched monitoring,
  provisioning support of large e-Science
  initiatives)
