Internet2, Indiana University and the Clean Slate Program at Stanford University have formed the Network Development and Deployment Initiative (NDDI), a partnership to create a new network platform and complementary software, which together will support global scientific research in a revolutionary new way. Through substantial investments by each of the partners, the NDDI will yield a new Internet2 Network service called the Open Science, Scholarship and Services Exchange (OS3E). OS3E and the NDDI capabilities will be developed and interconnected with links to Europe, Canada, South America and Asia, through coordinating international partners like RNP in Brazil, CANARIE in Canada, GÉANT in Europe, and JGNX in Japan, with additional service partners to be identified.
