Abstract

This paper presents a description of a discrete event simulation program developed to model the European AUTOVON (AUTOmatic VOice Network) of the Defense Communication System (DCS). AUTOVON is a telephone network characterized by a relatively small size, unpredictable and often fluctuating traffic loads, and a priority structure of calls and subscribers. The network is designed for survivability and proper operation in stress conditions. This paper briefly describes AUTOVON, indicates how a GPSS model was developed of the network, explains some of the logic flows involved in the model, and discusses several of the engineering and traffic control problems addressed by the simulation. And finally, the results generated by the simulation are presented. This simulation developed has not only provided valuable analysis aid for the present AUTOVON but also proved useful in designing the monitoring and control systems for the future AUTOVON.
