This document discusses how research and education networks can support remote collaborations. It provides examples of different types of data-intensive research that benefit from high-speed networks, including computational simulations, theoretical modeling, and empirical science projects. Specific examples highlighted include the Large Hadron Collider, telemedicine initiatives in Brazil, digital cinema, and science gateways. The key role of research networks in enabling access to instruments, repositories of learning objects and research data, identity federations, and remote conferencing is also summarized.
