X-WiNA Network Infrastructure for Research Projects
Martin WilhelmDFN-Verein, Berlin
Seite 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

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
Seite 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
Seite 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

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
