Computer-Aided Acquisition and Logistic Support Gateway Development
Abstract
DoD is committed to applying the best in modern technology to improve transfer of weapon systems technical information among DoD organizations and weapon systems contractors. To foster the application of such technology, DoD established the CALS steering group. The CALS communications working group provides advice and assistance to the steering group on data transmission requirements and communications protocols. This report explores how near- and mid-term gateway technologies make possible direct data communications among diverse hardware configurations. These gateways will facilitate the location, collection, and analysis of data across heterogeneous computer systems and data networks. LMI recommends that CALS participants implement gateway capabilities in the following order: Open Systems Interconnection (OSI)/DoD gateway, Standard Generalized Markup Language (SGML), Computer Graphics Metafile (CGM) and raster graphics, access to high-speed data networks, Initial Graphics Exchange Specification (IGES), and Product Data Exchange Specification (PDES). The order is based on the multiple protocol suites on data networks, the need to start with relatively simple textual data and progress to more complex graphics and manufacturing data, and the requirement for higher data speeds before larger files can be sent quickly. Implementation of these gateway capabilities is a critical step in achieving the interoperability and standardization goals of the CALS program.
