National Research Networks

• Science and Research have specific requirements
  to networking
• The general internet (Commodity Internet) in
  many cases cannot cover these requirements
• As a consequence, in nearly all countries
  National Research Networks (NRENs) have been set
  up
• To cover international requirements, a matching
  infrastructure is available

3
X-WiN Main Characteristics (1)

• Based on Dark Fiber (long term lease)
• Dual connected nodes with redundant fiber tracks
• (Almost) all nodes located on customer premises
• DWDM equipment dedicated to DFN, but owned,
  operated and serviced by Huawei (service contract
  with SLAs)
• Approx. 400 sites connected

4
X-WiN Main Characteristics (2)

• Dark Fibers to neighbour NRENs (Cross Border
  Fibers, CBF) PL, CH/IT, FR, NL
• Fiber Structure complemented by a few Managed
  Wavelength as shown on next slides
• DWDM equipment BWS 1600
• Carrier grade equipment
• Up to 1,6 Tbps (160 10 Gbps wave-lengths per
  fibre)
• Optical Protection feature

5
X-WiN Main Characteristics (3)

• Multiple ring structure with redundant fibre
  routing results in extremely high reliability
  ( 100 for IP Backbone)
• 0 packet loss in IP backbone, achieved by
  right-sizing of backbone capacity
• National point-to-point services can be provided
  with optical protection -gt no loss of
  connectivity in the event of fibre cuts
• 24 7 hotline

Services provided DFNInternet

• Main service DFNInternet
• General platform for TCP/IP based applications
  for worldwide access to National Research
  Networks (via GEANT2) as well as to the public
  internet (via private and public peerings and
  global IP transit)
• IP platform is centrally managed by DFNNOC (24
  7 hotline)

Services provided P2P Links I

• Many research projects only require connectivity
  between a limited number of sites, but at high
  capacity
• VPNs based on point-to-point wavelengths is the
  method of choice for these requirements
• Benefits
• Attractive price
• Full capacity available for project
• Increased reliability possible by use of cross
  border fibres

Conclusion

• For Research and Science in Germany, X-WiN
  offers the quality, reliability and coverage
  required by the most demanding projects
• All medium to large research facilities in
  Germany have been chosen to host a node of the
  X-WiN backbone, thus facilitating the provision
  of point-to-point links (no additional cost for
  local loops)
• NRENs provide the infrastructure for research
