Navy’s Automated Digital Network System (ADNS) serves as the WAN interface that connects mobile units to the tactical network over a satellite communication link. ADNS is a key component providing transport services to mission-critical network messages. This study develops a simulation test bed to investigate the performance of ADNS Increment III. Several test scenarios were developed for this study. The performance of video and audio applications is presented. Test results suggest that QoS is required at the core routers to improve the network performance.
Andy Peng joined Lockheed Martin-MS2 Tactical Systems as a systems engineer in 2005. He had been working on tactical network modeling and simulation related projects. In 2003-2004, Andy held a research intern position with Honeywell International while studying in M.S. program. The tasks involved paper research in modeling on-chip RF inductors and evaluating simulation tools. In 1999-2002, Andy held test, sustaining, and design engineering positions at Dell Inc. His primary job function was designing personal computers for different market segments. Andy Peng received B.S. degrees in electrical engineering and computer science from Texas Tech University in 1999, and the M.S. degree in electrical engineering from University of Minnesota in 2004. He is currently a Ph.D. student at University of Minnesota.
