Defense Advanced Research Project Agency Programs

Directed next generation mobile, wireless networking programs. Research and development focused on robust, automatically reconfigurable, internetworking capability (backbone node mobility; prioritized traffic control; predictive routing; and topology management) to support tactical users in rapid deployment and high-mobility scenarios. These next generation technologies, implemented in the UAV On Board Switch project will also provide assured access, mobile multimedia (voice, data and video) information requiring higher bandwidth than is currently available in the wireless domain.

Managed a Small Business Innovation Research project, which developed a low-cost, all-optical backbone network capable of interconnecting computers using a wide range of high performance protocols and allows for dynamic acquisition of fiber optic backbones.

Developed the communications infrastructure to support the Synthetic Theater of War Advanced Concept Technology Demonstration. Research and development focused on aggregating multicast groups and translating quality of service in an IP over ATM network. Demonstrated this system proof-of-concept, prototype and scalability in the largest distributed interactive simulation engineering demonstration of its kind.

Directed the Defense Simulation Internet (DSI), a worldwide real-time internetwork, consisting of 10 major backbone nodes, approximately 100 sites, 665 routers, network encryption units, and multiple levels of security. The DSI was the communications infrastructure for the first DOD demonstration of an operational linking of distributed, joint service constructive and live simulations with actual systems in a large-scale synthetic battle.
