among computers on the grid. For example, relatively slow-speed DSL and cable modem connections
are used by many of the experimental grid systems, such as the Folding@home project at Stanford
University. The system uses standard DSL and cable modem networks, which provide between 125
Kbps and 1 Mbps throughput, to connect over 20,000 PCs to form a grid computer. The higher-speed
grid systems are necessarily limited to MAN distances using conventional Internet connections or
WAN distances with much higher-speed network connections. For example, the Department of
Energy's Science Grid project is based on a 622 Mbps fiber network running a suite of software that
includes Globus grid software.
