Ada-based real-time network environment

The design of communications architecture to support Ada-based, real-time, distributed processing systems is described. An implementation of this architecture compatible with the open systems interconnection (OSI) seven-layer reference model is discussed. The foundation Ada real-time network environment (FARNE) is designed and implemented to provide a standard network communications interface to the distributed Ada applications such as those found in tactical systems. FARNE is also designed to support the low latency communication requirements commonly associated with the embedded/tactical systems. The development of FARNE has evolved through several iterations. It currently supports both Unix environment and the embedded processors. FARNE has been tested using optical and nonoptical media. The design and implementation of the FARNE are presented. Key conclusions drawn from results of extensive performance tests and plans for future implementations and enhancements are discussed
