- 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.
