The CASA Gigabit Testbed  achieved a record for data transmission across a wide-area network with rates up to 550 Mbits/second.

Between a Cray Y-MP at the Los Alamos National Laboratory (LANL) and a Cray C90 at SDSC, a path separating the computers by some 2,000 kilometers, about 2 Mbytes of sustained data in flight over the fiber-optic channel was required. The CASA Gigabit Testbed linked computers at LANL, SDSC, Caltech, and the Jet Propulsion Laboratory via multiple OC-3 SONET channels provided by US West, MCI, and Pacific Bell. Gateways developed at LANL linked up to seven OC-3 channels to HIPPI networks at each site. The record bandwidth was achieved by striping HIPPI local-area networks through the LANL gateway across seven OC-3 channels.
