We will present the rapid progress, vision and outlook across multiple state of the art development lines within the Global Network Advancement Group and its Data Intensive Sciences and SENSE/AutoGOLE working groups, which are designed to meet the present and future needs and address the challenges of the Large Hadron Collider and other science programs with global reach. Since it was founded in the Fall of 2019 and the working groups were formed in 2020, in partnership with ESnet, Internet2, CENIC, GEANT, ANA, RNP, StarLight, NRP, N-DISE, AmLight, and many other leading research and education networks and network R&D projects, as well as Caltech, UCSD/SDSC, Fermilab, CERN, LBL, and many other leading universities and laboratories, the GNA-G working groups have deployed expanding virtual circuit and programmable testbed spanning six continents which supports continuous developments aimed at the next generation of programmable networks interworking with the science programs' computing and data management systems. The talk will cover examples of recent progress in developing and deploying new methods and approaches in multidomain virtual circuits, flow steering, path selection, load balancing and congestion avoidance, segment routing and machine learning based traffic prediction and optimization. Examples of results demonstrated at the Supercomputing 2022 conference (SC22) and under persistent development will be included.
