This paper proposes a communication middleware of distributed real-time application referencing AUTOSAR standard by requirements of real-time and flexible configuration mechanism. It has reusability, tailorability and configurability, can hide the difference of communication protocols and be used to different operation system and platforms. Application case analysis of a communication middleware show its feasibility. 【Key words 】Distributed Real-time Systems(DRS); middleware;
