A Total AUTODIN System Architecture

This paper concerns data communications in the U.S Department of Defense. It includes a historical perspective on DoD common-user data systems: AUTODIN I, ARPANET, and AUTODIN II. It treats data communications on an end-to-end basis, including automation of communications center functions by the user. The Integrated AUTODIN System Architecture (IASA) project was defined by DoD to provide a total data communications system design on an end-to-end basis. The main results of this paper are based on IASA work and include the use of AUTODIN II as the IAS backbone, the integration of AUTODIN I and AUTODIN II, the definition of a new DoD program called the Inter-Service/Agency Automated Message Processing Exchange (I-S/A AMPE), the development of DoD standard protocols, formats and procedures, a brief description of the IAS security architecture, and a plan for internetting different networks via gateways and internet protocols. A plan for the future disposition of the ARPANET is included. The paper concludes with some speculative material on the long-range future of United States military data communications.
