Internet 2 Adds More Bang for the Click

University of Nebraska-Lincoln is the first Internet2 member to take advantage of the Dynamic Circuit Network (DCN) as a part of its development trial.

At its fall 2007 members' meeting, Internet2 announced the completion of a new nationwide advanced network infrastructure. With an initial capacity of 100 gigabits per second (gbps) nationwide and a revolutionary DCN providing dedicated bandwidth-on-demand capabilities, the new infrastructure provides the potential to transform research-focused areas of study.

The meeting demonstrated the DCN's ability to support the networking demands of high energy physicists collaborating on the Large Hadron Collider (LHC) experiment. With one mouse click, Dr. Carl Lundstedt of UNL's Department of Physics and Astronomy set up a 10 Gbps dedicated circuit between the UNL campus and Fermilab in Batavia, Ill. The result was that the data traffic flowing across the shared IP network seamlessly switched over to the DCN and quickly transferred one-third of a terabyte of data (equivalent to the capacity of 40 standard DVDs).

"The LHC experimentation that our campus will be involved in over the next several years brought about an immediate need for us to explore new ways of networking that can support the intense short term demands of our researchers," said Dale Finkelson, network engineer with UNL Information Services. "Internet2's new Dynamic Circuit Network holds the promise of providing cost-effective, on-demand bandwidth that can easily handle these powerful requirements. Not only does the DC network provide a platform for our LHC needs, but it provides a pathway for our community to explore new applications and technologies."

Internet2 members in the science and engineering communities are using high-performance networking for interactive collaboration; distributed data storage and data mining; large-scale, multi-site computation; real-time access to remote resources; dynamic data visualization; and shared virtual reality. The science and engineering communities are also actively engaged in Internet2's middleware and network performance initiatives, among others.
