GLIF, the Global Lambda Integrated Facility, would like to announce the availability of new world maps that showcase the global research and education multi-gigabit optical network infrastructure owned by its participating organisations. GLIF is a virtual organisation (or facility) that consists of network providers, network engineers, computer scientists and computational scientists.
The new map features 60 participating networks representing 34 countries and multi-country organisations. GLIF itself owns no resources, so relies on its participants – from National Research and Education Networks, consortia, institutions and individual research initiatives – to share network resources, information and knowledge. In turn, this provides multidisciplinary research teams with shared cyberinfrastructure on which to cooperatively and collaboratively develop, test and implement new optical networking technologies, middleware and applications of global importance.
GLIF organisations that provide bandwidth have capacity in excess of what is required for production usage, which they make available to global research teams, pending availability. These optical networks interconnect and interoperate at GLIF Open Lightpath Exchanges (GOLEs) and Open Exchanges (OXs), creating a global advanced networking fabric that dynamically connects computing, storage, visualisation, and instrumentation facilities at collaborating sites around the globe. Note: The GLIF map does not show international capacity dedicated to production usage.
The GLIF 2017 map was created by Robert Patterson of the Advanced Visualization Laboratory (AVL) at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign (UIUC), using an Earth image provided by NASA with texture retouching by Jeff Carpenter, NCSA. Data was compiled by Maxine D. Brown of the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC). Support was provided by GLIF, NCSA/UIUC, UIC, and the State of Illinois.
