Deutsches Forschungsnetz Creates National Research and Education Network Based on Cisco IP NGN Architecture and Featuring the Cisco CRS-1


Cisco® today announced at the TERENA Networking Conference that it has been selected by Deutsches Forschungsnetz (DFN), Germany’s National Research and Education Network (NREN), to deliver the core routing platform for a new national backbone that will put the NREN at the forefront of innovation in Europe while delivering significant operational expenditure savings.

X-WiN is operated by the DFN Society (DFN-Verein) - a nonprofit association established by the research, development and education sector in Germany in 1984 and currently has 351 institutional members. The network supports German work in areas such as high-energy physics research and grid computing, and it is linked to the North American and European scientific networks ABILENE and GÉANT2, as well as the Distributed European Infrastructure for Supercomputing Applications.

“After analyzing the possible designs for our new network, we were satisfied that Cisco was able to add the most value and deliver the most innovative technology in the form of the Cisco CRS-1 Carrier Routing System,” said Jochem Pattloch, managing director of DFN. “Our intention is to reduce the operational expense of running a large number of gigabit routers. In upgrading to the CRS-1 we have been able to do that - as as well as putting in place a foundation that keeps us at the forefront of NREN innovation in Europe.”

Cisco 12000 Series Routers allow the existing G-WiN network to offer connection speeds of up to 10 gigabits per second. In X-WiN, these platforms will be completely replaced by a collapsed core design (where both distribution and core functions are provided within the same devices) based on the logical router capability of several Cisco CRS-1 Carrier Routing Systems. When they are linked using Internet Protocol (IP) over dense wavelength-division multiplexing, they would provide connections of up to 40 Gbps. X-WiN’s edge, meanwhile, will be based on Cisco 7600 Series Routers with shared port adapters that are compatible with the CRS-1 platform.

“With DFN we have been able to demonstrate how the CRS-1 offers unbeatable value for NREN deployments,” commented Yvon Le Roux, vice president of the public sector for Cisco in European markets. “It is capable of creating points of presence with a much greater port density at a very low cost, resulting in important operational cost savings combined with the potential to create much larger and faster networks.”

Cisco provides many leading NRENs with the tools and technologies to drive innovation and build the high-capacity, high-performance networks essential for the sharing of ideas, data and learning. To deepen the relationships with NRENs in Europe, Cisco has a dedicated team of research and development technical experts supported by a sales team that focuses solely on working with NRENs throughout the region.

The Cisco CRS-1 and its Cisco IOS® XR modular operating system are the result of Cisco’s proven 20-year track record in routing innovations through focused research and development programs. It provides carriers with high-performance core routing capabilities and rounds out Cisco’s existing carrier-class routing portfolio, which is ideally suited to deliver cost-effective IP services.
