OCN is an organization that coordinates and operates a high-performance communications network used by research institutions, laboratories, cultural institutions, and government-funded projects. It provides advanced networking, data transport, and collaboration services linking universities, national laboratories, museums, archives, and research centers. OCN supports large-scale data transfers, distributed computing, and multidisciplinary collaborations across continents.
OCN interconnects major research and educational institutions such as Massachusetts Institute of Technology, Stanford University, University of California, Berkeley, California Institute of Technology, Harvard University, Princeton University, University of Oxford, University of Cambridge, University of Tokyo, ETH Zurich, CERN, National Institutes of Health, Los Alamos National Laboratory, Lawrence Berkeley National Laboratory, Argonne National Laboratory, Brookhaven National Laboratory, Fermilab, Oak Ridge National Laboratory, NASA, European Space Agency, Max Planck Society, Wellcome Trust, Smithsonian Institution, British Library, Bibliothèque nationale de France, European Organization for Nuclear Research, Nanyang Technological University, Tsinghua University, Peking University, KAIST, Seoul National University, Australian National University, University of Toronto, McGill University, University of British Columbia, Instituto Tecnológico de Monterrey, Universidad Nacional Autónoma de México, São Paulo Research Foundation, Council of Scientific and Industrial Research, Indian Institute of Science, Indian Institutes of Technology, National Supercomputing Centre (Singapore), Barcelona Supercomputing Center, Centro Nacional de Supercomputación and others to facilitate data-intensive science. It enables collaborations spanning projects like Human Genome Project, Large Hadron Collider, Event Horizon Telescope, Square Kilometre Array, International Thermonuclear Experimental Reactor, LIGO, ALMA Observatory, James Webb Space Telescope, Hubble Space Telescope, Voyager program, Artemis program, Mars Reconnaissance Orbiter, and NOAA programs.
OCN traces its origins to early regional research networks and national backbone initiatives that emerged alongside projects such as ARPANET, NSFNet, JANET, SURFnet, GÉANT, Internet2, CANARIE, AARNet, and NORDUnet. Key historical milestones include upgrades to wavelength-division multiplexing infrastructure influenced by work at Bell Labs, AT&T, and Lucent Technologies and cross-border linking efforts involving European Commission research programs and National Science Foundation funding. OCN evolved through partnerships with supercomputing centers such as National Center for Supercomputing Applications, Pittsburgh Supercomputing Center, Texas Advanced Computing Center, San Diego Supercomputer Center, Sainsbury Laboratory, John von Neumann Institute for Computing, and investments by agencies like Department of Energy, Defense Advanced Research Projects Agency, European Research Council, Japan Science and Technology Agency, National Natural Science Foundation of China, and philanthropic organizations such as Gordon and Betty Moore Foundation, Bill & Melinda Gates Foundation, and Alfred P. Sloan Foundation.
OCN delivers services including high-bandwidth point-to-point links, wavelength services, virtual private circuits, and peering for research traffic between institutions like MITRE Corporation, RAND Corporation, Brookings Institution, Carnegie Mellon University, Columbia University, Yale University, and University of Chicago. It provides support for data replication used by projects such as GenBank, European Nucleotide Archive, Protein Data Bank, Dryad (repository), Zenodo, Figshare, and Internet Archive. OCN enables secure scientific workflows for collaborations involving World Health Organization, Centers for Disease Control and Prevention, European Centre for Disease Prevention and Control, Food and Agriculture Organization, International Monetary Fund, and World Bank research units, and supports content distribution for cultural partners like Metropolitan Museum of Art, Victoria and Albert Museum, Louvre, Prado Museum, Uffizi Gallery, and Tate Modern.
OCN’s infrastructure comprises fiber-optic backbone rings, dense wavelength-division multiplexing (DWDM) systems, optical amplifiers, and programmable switches from vendors and collaborators including Cisco Systems, Juniper Networks, Ciena, Infinera, Nokia, Huawei, Arista Networks, Mellanox Technologies, Broadcom Inc., and Intel Corporation. It interconnects with national research and education networks such as Internet2, GÉANT, CANARIE, SURFnet, AARNet, RESTENA, RedCLARA, REUNA, SANET, and regional exchange points like LINX, DE-CIX, AMS-IX, Equinix, IX.br, JPNAP and peering fabric within Amazon Web Services, Microsoft Azure, Google Cloud Platform, Oracle Cloud for hybrid cloud workflows. Edge services leverage high-performance data transfer tools and protocols inspired by GridFTP, Globus (service), Rsync, Aspera, BBcp, and research middleware from Open Grid Forum standards.
OCN is governed through a consortium model with representation from universities, national laboratories, cultural institutions, and funding bodies including National Science Foundation, European Commission, U.S. Department of Energy, Japan Science and Technology Agency, Canadian Tri-Agency, Australian Research Council, Research Councils UK, Deutsche Forschungsgemeinschaft, and regional ministries of science and technology. Funding derives from a mix of governmental grants, membership fees from institutions like Ivy League, Russell Group, Group of Eight (Australian universities), U15 Group of Canadian Research Universities, and contracts with projects such as CERN OpenLab, ELIXIR, Horizon 2020, Horizon Europe, PRACE, and philanthropic initiatives.
OCN supports research in high-energy physics, genomics, astronomy, climate modeling, computational chemistry, and machine learning for institutions like Los Alamos National Laboratory, CERN, European Southern Observatory, National Oceanic and Atmospheric Administration, European Space Agency, Joint Genome Institute, Wellcome Sanger Institute, Allen Institute for Brain Science, Janelia Research Campus, and Flatiron Institute. Applications include real-time data streaming for instruments such as Large Synoptic Survey Telescope, Square Kilometre Array, Event Horizon Telescope, and distributed analysis platforms like HTCondor, Apache Spark, Kubernetes, Slurm Workload Manager, and Hadoop ecosystems.
OCN engages in outreach with doctoral programs, summer schools, workshops, and conferences including Supercomputing Conference (SC), Internet2 Global Summit, TERENA Networking Conference, GÉANT Conference, International Conference for High Performance Computing, Networking, Storage and Analysis, NeurIPS, ICML, AAAS Annual Meeting, and collaborates with professional societies such as IEEE, ACM, American Physical Society, Royal Society, European Research Advisory Board, and National Academies of Sciences, Engineering, and Medicine to train network engineers, researchers, and data scientists. Educational partnerships extend to museums and libraries like British Library, Library of Congress, Smithsonian Institution, National Archives, and initiatives promoting digital preservation and open science.
