Real-time service integration of defense information system

Abstract

This study designs a reference model of the Defense REST API server based on the representational state transfer (REST) architecture style to present the most efficient, stable, and sustainable technical criteria for real-time service integration of defense information systems in Korea. The purpose of this component is to provide evidence to be stipulated as part of the Korean Defense Ministry's instructions and regulations, such as the Defense Interoperability Management Directive and the Interoperability Guide, and to support the development of the National Defense Interworking Technology and Interoperability. As the defense information system was subdivided and developed by the army, navy, air force, or business functions, interworking between information systems has become one of the most important factors. However, despite the need for advanced service integration and interworking, various interconnection service modules based on enterprise application integration (EAI), EAI hubs, and spokes were developed at a level that met local requirements (simple data transmission) without specific criteria for each network or information system. As a result, most of the interconnection modules currently in operation suffer from the absence of a technical spectrum, such as not meeting the military's demands for real-time interconnection and service integration, which increases with time. Therefore, this study seeks to identify the above problems by integrating the defense information system into one service and presenting a reference model of the defense REST API server to meet various real-time interworking requirements, analyze the technical basis, and pursue a model that fits military reality.
