The Internet2 Dynamic Circuit Network (DCN) is a revolutionary, optical circuit network that provides dedicated bandwidth for the most demanding applications. Currently under development, the Internet2 DCN uses community-developed, standards-based technologies and protocols to provide on-demand, dedicated optical paths between endpoints. Just as the R&E community led the way decades ago in expanding the reach and capabilities of packet networking using the IP and TCP protocols, the new Internet2 DCN breaks new ground to provide the U.S. research and education community dedicated, customizable, on-demand bandwidth.
Dynamic Circuit Research (R&D) through Internet2 partners
“A key concept in the NSF’s Cyberinfrastructure vision is that network capacity should be available as a schedulable, on-demand resource—just like a supercomputer or radio telescope is today. The idea is that researchers, scientists, artists, or faculty can tap into deep bandwidth resources whenever and wherever they need it. We believe the new Internet2 Dynamic Circuit Network, which was developed through collaboration with our community, brings this important vision to fruition.”

DCN Pilot Project
To support the development, deployment, and use of innovative hybrid optical networking capabilities, Internet2 is initiating a no-fee trial of the Internet2 DCN. Interest is invited from any Internet2 Connector with a connection to the Internet2 IP Network. All interested Internet2 Connectors should send an email to email@example.com. Information about this project is included in recent presentations and relevant publications (see Quick Links). Here is a link to the most recent DRAFT document.
Internet2 Connector Status
Follow this link to a list of the Internet2 Network Connectors and their participation status in the DCN Pilot Project. For participating Connectors, contact people at the connector organizations are listed. Usage reports for participating connectors are available HERE.
Internet2 DCN Research
A variety of research projects are actively using the Internet2 DCN and other global DCN capabilities in their research. These include LIGO, e-VLBI, and UltraGrid/CoUniverse, among others. Here are links to several of these projects and their DCN-specific materials:
