SAFENET-a Navy approach to computer networking

The SAFENET (survivable adaptable fiber optic embedded network) standards which are being developed for use in US Navy computer-based systems, are described. There are two SAFENET standards. SAFENET I is based on the IEEE 802.5 LAN standard, while SAFENET II is based on the fiber distributed data interface (FDDI). The SAFENET physical topology is based on a dual counter-rotating ring architecture which provides many survivability features. The SAFENET program has been successful in defining a set of network profiles which will meet the requirements of Navy shipboard combat systems. These standards provide many advantages over current interconnection methods, including use of fiber optics, system survivability, and use of commercial standards.<
