Japan's NICT, in collaboration with AARNet, CERN, GÉANT, and others, coordinated ten 100 Gbps network paths between Tokyo and Atlanta, creating a global experimental network for groundbreaking demonstrations at SC24.
A group of international research and education networks and organisations came together at the 2024 Super Computing conference (SC24) in Atlanta, Georgia USA in November, to drive groundbreaking advancements in high-speed data transfer and secure communications. Japan’s National Institute of Information and Communications Technology (NICT), in collaboration with AARNet, CERN, GÉANT, and many others, coordinated ten international 100 Gbps network paths connecting Tokyo and Atlanta—forming the foundation of a world-scale experimental network that powered a series of innovative demonstrations.
This collaboration enabled several key experiments, including the MMCFTP data transfer project by the National Institute of Informatics. Using ten 100 Gbps lines, the team set an ambitious target of 800 Gbps and achieved an impressive 466 Gbps, despite challenges such as traffic interference and limited full-channel availability. These insights pave the way for refining high-speed file transfer protocols in the future.
Another standout demonstration was by Osaka University and Shimane University, who showcased a terabit-scale anonymous communication protocol leveraging programmable P4 switches. Their innovative approach delivered nearly 588 Gbps throughput, even supporting a live 4K video stream—an achievement that earned them the prestigious SCinet Spirit of Innovation Award. This achievement highlights the potential of lightweight, high-speed privacy-preserving protocols to transform secure communications on a global scale.
Further illustrating the strength of international cooperation, Kyushu Institute of Technology and KDDI Research demonstrated a Floating Cyber-Physical System (F-CPS) designed for local data production and consumption. This system used secure, wireless communication and advanced packet filtering to transfer LiDAR point cloud data from Japan to the United States in real time. Although minor issues with wireless congestion were noted, the demonstration successfully underscored the potential of F-CPS technology in managing and safeguarding localised data.
SC24 provided the perfect platform for these groundbreaking demonstrations, setting the stage for future innovations in high-speed data transfer and secure networking.
