The Defense Information System Agency (DISA) has managerial and engineering responsibility for a circuit-switched network currently known as the Defense Information System Network–Voice. This network was originally implemented in the 1960s and was known as the Automatic Voice Network. Throughout this time, DISA has used a network design and analysis model to reconfigure the network. This model was developed in the early 1970s, has been continually enhanced, and is used on a weekly basis to engineer and manage the network. Since 1975, it has been used to save the United States government approximately $1,400,000,000.00. In this paper, we present a chronology of its development, enhancement, and use.
