1. X-WiN A Network Infrastructure for Research Projects
Martin Wilhelm
DFN-Verein, Berlin

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

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
