FCS Network - Services Layer
Central to FCS (BCT) network implementation is the Services Layer, commonly referred to as System-of-Systems Common Operating Environment (SOSCOE), which supports multiple mission-critical applications independently and simultaneously. It is configurable so that any specific instantiation can incorporate only the components that are needed for that instantiation. It enables straightforward integration of separate software packages, independent of their location, connectivity mechanism and the technology used to develop them.
The Services Layer architecture uses commercial off-the-shelf hardware and a Joint Tactical Architecture-Army compliant operating environment to produce a nonproprietary, standards-based component architecture for real-time, near-real-time, and non-real-time applications. The Services Layer also contains administrative applications that provide capabilities including login service, startup, logoff, erase, memory zeroize, alert/emergency restart and monitoring/control.
The Services Layer framework allows for integration of critical interoperability services that translate Army, Joint, and coalition formats to native, internal FCS (BCT) message formats using a common format translation service. Because all interoperability services use these common translation services, new external formats will have minimal impact on the FCS (BCT) software baseline. The FCS (BCT) software is supported by application-specific interoperability services that act as proxy agents for each Joint and Army system. The Battle Command (BC) Application Layer can access these interoperability services through applicable program interfaces that provide isolation between the domain applications, thereby facilitating ease of software modifications and upgrades.
The Services Layer is the open architecture middleware of the FCS (BCT) Network; it provides a window to the Situational Awareness Data Base and enables the interactive functioning of the Applications Layer and the Network Manager. In addition, the Services Layer provides message translation services to achieve Joint, Interagency, and Multinational (JIM) interoperability.
FCS will employ an integrated computer system to host the System-of-Systems Common Operating Environment (SOSCOE), ensure common processing, support networking and employ consistent data storage/retrieval across all FCS platforms and applications. The integrated computer system consists of processors, storage media, dynamic memory, input/output devices, local area networks (LANs) and operating systems. A suite of seven computing system types have been identified to meet the various FCS platform-specific requirements for security, processing capability, computational capacity, throughput, memory, size, weight and power.
