USAN (University Satellite Network) is a discipline oriented
network serving organizations that do research in the atmos-
pheric and oceanographic sciences. Current members are the
Universities of Miami, Oregon State, Penn State, Maryland,
Wisconsin, and the Institute of Naval Oceanography, the
Naval Research Lab, and Woods Hole Oceanographic Institute.
The primary use of the network is for access to supercom-
puter facilities at NCAR. Secondary use is for access to the
Internet via the NSFnet node and other Internet gateways at
NCAR.
The network is an IP satellite broadcast network with a star
configuration with the center at NCAR. Incoming traffic is
broadcast at 56Kbits from each node on its own unique chan-
nel. Outbound traffic is broadcast at 224Kbits on a single
channel.
Membership in USAN is not restricted, however members must
share in the operating costs for the network.

Any IP host of any USAN member may access the network.
