Internet2 Demonstrates Dynamic Optical Circuit Interoperability

At this week's SC07 high-performance computing conference in Reno, Internet2 participants are demonstrating interoperability of its Dynamic Circuit (DC) Network with multiple regional and international networks as well as an equipment provider. Dynamic optical circuits provide on-demand or scheduled dedicated point-to-point bandwidth.

The Internet2 Dynamic Circuit (DC) Network, unveiled earlier this year, is a nationwide optical circuit network that provides short term, on-demand access to dedicated bandwidth up to 10 Gbps to serve the most demanding network applications like those involved in high-energy physics research, telemedicine and radio astronomy.

The Internet2 demonstrations will showcase interoperability with ESnet, GEANT2 in Europe, the Great Plains Network (GPN), GRNET in Greece, HEAnet in Ireland, Merit Network, Northern Crossroads (NoX), a Nortel Network based in Ottawa, Canada, the PIONIER network in Poland, and the Phosphorus testbed at the University of Amsterdam via SURFnet's NetherLight GLIF Open Lambda Exchange in Amsterdam.

The interoperability of the Internet2 DC Network with other dynamic circuit networks is enabled by the Inter-Domain Controller (IDC) protocol developed in a collaboration by GEANT2, Internet2, and ESnet and is used widely in this community as the standard for interoperable dynamic circuit networking today. The University of Amsterdam is working to extend the protocol and other collaborators are expected to participate in further development as well.
