Deutsche Telekom's T-Systems Interconnects Data Centers at 100 Gbps

T-Systems, Deutsche Telekom's corporate customer arm, has interconnected the data centers of the Dresden and Bergakademie Freiberg technical universities with a 60 km link using commercial 100 Gbps IP and optical technologies. The link uses a single 100G wavelength across Alcatel-Lucent's optical transport systems and IP Service routers.

Core elements of the 100G solution deployed between the technical universities of Dresden and Bergakademie Freiberg are the Alcatel-Lucent 1830 Photonic Service Switch, featuring 100G next-generation coherent technology, and the Alcatel-Lucent 7750 Service Router with 100G Ethernet interfaces.

In addition, Ixia assisted Deutsche Telekom in testing a pre-deployment 100 Gbps network link. Deutsche Telekom used Ixia's higher speed Ethernet (HSE) K2 test platform to generate and analyze full 100 Gbps line rate traffic. K2's routing and MPLS protocol emulation allows testing of control plane performance in parallel with layer 2-3 metrics such as real-time latency, inter-arrival time, packet loss, data integrity, and sequence checking. Ixia's K2 modules support unframed bit error ratio testing (BERT), allowing individual PCS lane BER test and error injection over a wide range of PRBS patterns, including support for PMD's in IEEE802.3ba draft standard.

The 100G technology is expected to improve the cooperation between research facilities and will be used to facilitate more advanced cloud service delivery options and pave the way for proliferation of collaborative multimedia applications. Researchers of both universities are using the installation to study the resource requirements of clustered virtual servers, Lustre wide-area file systems, network-attached storage and real-time video conferencing applications under heavy load.

"Research data centers, with their exceptional computing power and bandwidth demands, are excellent early adopters for this technological innovation", says Adolfo Hernandez, President of Alcatel-Lucent EMEA. "With Alcatel-Lucent's considerable experience in IP routing and optical technologies, and the timely availability of their commercial offerings, we are uniquely positioned to provide 100G across the IP and optical network for seamless, end-to-end high performance, even for the most advanced collaborative and cloud-based applications currently being developed."
