The Advanced Technology Demonstration Network (ATDnet) is a high-performance networking testbed in the Washington D.C. area. It is intended to be representative of possible future Metropolitan Area Networks. Established by the Defense Advanced Research Projects Agency (DARPA) to enable collaboration among Defense and other Federal agencies, ATDnet has a primary goal to serve as an experimental platform for diverse network research and demonstration initiatives.
The ATDnet concept is to interconnect several agency sites with high-speed fiber optic transmission media and to overlay this media. Pair-wise and multiple party research initiatives and experiments are planned over the lifetime of the testbed. Experimental testing of the bitways and a diversity of service and applications experiments are intended to gain insight into the potential of this new performance level.
