Communications among multiple Ada programs is a must, either as an explicit link or as an invisible link hidden beneath a distributed Ada veneer. Unisys has defined two Ada package specifications for inter-program communications, that are derived from the requirements developed at the Third International Workshop on Real-Time Ada Issues (RTAW3). Unisys is implementing these packages on several embedded real-time testbeds, both as standalone capabilities for application developers and as the communication layer supporting a distributed Ada system. These specifications are proposed as a basis for a secondary standard for inter-program communication for Ada9X.This paper describes how these specifications match the RTAW3 requirements and the motivation for their features. Some details of the specifications are interspersed throughout the text, with a full specification contained in the appendix.
