Integration of Digital, Voice, and Video Data on a Multilevel Secure Fiber Optic Network

An advanced technology Local Area Network is being developed for application to military C³I systems. In addition to incorporating Multilevel Security controls, the network utilizes wavelength division multiplexed fiber optics to provide simultaneous transmission of digital, voice, and video traffic at data rates up to 150 Mbps. Interfaces to heterogeneous serial devices, work stations, and processors are being developed. User services embedded in the network include terminal connection, interprocess communication, file transfer, electronic mail, voice connection and conferencing, video distribution, and circuit switched stream data distribution. DOD standard protocols are embedded in the network. The network is designed to meet the DOD Computer Security Center´s Al multilevel security criteria. The IEEE 802.4 token bus protocol is used for network digital services. Initial performance demonstrations of this IR&D project have been completed. Full MLS functionality is projected for year-end 1985.
