A GENERIC ARCHITECTURE FOR DISTRIBUTED, NON-STOP, MISSION AND SAFETY CRITICAL SYSTEMS

摘要

This paper gives an overview of a prototype architecture for distributed, non-stop, mission and safety critical systems developed in the MISSION research project. After outlining some of the issues involved in supporting these requirements at the systems software level, the paper describes the MISSION generic architecture from two perspectives. First, it discusses the visualization techniques used to handle the complexity of a large object-oriented system. Second, it describes the structure of the bottom architectural level, known as the smokestack model, which is composed of five firewalled subsystems interacting by means of a special MASC kernel.
