Adapting the end-to-end flow model for distributed Ada to the ravenscar profile

This paper presents a proposal to develop High-integrity Distributed Real-Time (HDRT) systems by integrating the real-time end-to-end flow model with the Ravenscar profile. Although this profile is being widely used in the development of single-processor critical hard real-time systems, further research is required to apply this profile in a distributed environment. This work is built upon the endpoints pattern, a technique that we have used to integrate the end-to-end flow model into Ada's Distributed Systems Annex (DSA). We adapt our previous work to the requirements of the Ravenscar profile. Therefore, this paper gives a step forward and discusses the modifications needed to make a specific instance of the endpoints pattern compatible with Ravenscar.
