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
