- The NASA Science Network (NSN) is an IP network which sup-
- ports scientists and flight projects funded by NASA's Office
- of Space Science and Applications (OSSA). The network is
- used to provide remote access to such resources as scien-
- tific databases and supercomputing centers. The NSN main-
- tains hubs at several NASA centers which are interconnected
- in a partial mesh topology. These backbone sites use terres-
- trial circuits ranging in speed from 168 to 672 Kbps. From
- these hubs radiate numerous tail circuits; the majority of
- these tails are 56 Kbps, with a few at 9.6 Kbps as well.
-
- The NSN was designed to provide NASA's scientific communi-
- ties with a more general networking approach that would pro-
- vide full networking services in a vendor-independent
- environment. These services include file transfer and remote
- logon as well as email.
-
- NSN is a NASA-wide network managed by the NASA Science
- Internet Project Office (NSIPO) at Ames Research Center. It
- is used for NASA-funded space science research programs and
- flight projects.
-
- Users include NASA sites, and government facilities,
- research, and academic sites conducting NASA-funded
- research.

- In addition to NSN, the NASA Science Internet also operates
- SPAN, the Space Physics Analysis Network which utilizes DEC-
- net protocols. NSI maintains applications gateways that pro-
- vide connectivity between SPAN and NSN.
