The next generation of DOE large-science facilties, projects and programs have requirements that will drive extreme networking, in terms of sheer throughoputs as well as capabilities needed for remote visualizations. computational steering and instrument control. These network capabiltiies require quantum leaps in a number of technologies including provisioning, transport and application endowment. The research, development and testing activities for these network capabitlies can not be adeqautely supported by current testbeds and simulators.

The UltraNet is a research network funded by DOE Office of Science that provides a cross-country testbed consistinng of multiple wavelengths provisioned on-demand. It provides the capabiltiies of:
