SWIM Segment 1 Approach
Rather than developing a separate SWIM infrastructure, the program will provide Service Oriented Architecture (SOA)-based standards, guidance, and core capabilities software to National Airspace System (NAS) programs that will host the software on their existing hardware. SOA technology allows software applications to locate and interact with one another through information services that can be accessed without knowledge of the application’s underlying platform implementation. SWIM maximizes the use of current infrastructure and will be developed incrementally based on the needs of various data communities, maturity of concepts of use, and implementation phased segments that are sized to fit reasonable cost, schedule, and risk thresholds.
SWIM is being implemented in segments. In each segment an appropriate set of NAS applications will be developed and integrated into SWIM. Core services will be added as required to support the implementation capabilities associated with the segments. SWIM core services will enable systems to request and receive information when they need it, subscribe for automatic receipt, and publish information and services as appropriate. This will provide for sharing of information among diverse systems.
To define Segment 1, SWIM collaborated with Communities of Interest (COIs), groups of stakeholders that collectively possess the expertise to accurately describe how information is currently used in the NAS. COIs also provided information pertaining to future NAS information needs and helped analyze how to best fulfill those needs using a net-centric solution. COIs currently include Aeronautical Information Management (AIM), Flight and Flow Management (F&FM), and Weather; others will form as needed over time.
The COIs identified nine capabilities that SWIM Segment 1 will provide. Using SWIM provided SOA-based standards, guidance, and core capabilities software, SWIM Implementing Programs (SIPs) will be responsible for the implementation of the SWIM nine capabilities shown below. The nine capabilities will be provided by seven participating SIPs: En Route Automation Modernization (ERAM), Traffic Flow Management (TFM), Aeronautical Information Management (AIM), Terminal, Corridor Integrated Weather System (CIWS), Integrated Terminal Weather System (ITWS) and Weather Message Switching Center Replacement (WMSCR).
