  1. X-WiNA Network Infrastructure for Research Projects Martin Wilhelm DFN-Verein, Berlin wilhelm@dfn.de

  2. 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 -> no loss of connectivity in the event of fibre cuts • 24 * 7 hotline

  8. 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)

  10. 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

  11. Services provided: P2P Links • 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 by use of cross border fibres (fibre routes divers from GEANT2)

  13. 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
