Two main technologies for achieving reliable real-time distributed communications systems are described. One is the technology to prevent the influence of a fault in an autonomous distributed system from spreading to the whole system (called autonomous distributed system control). The other is a software structure based on distributed processing, the object-oriented approach, and layering for better maintainability and expandability (called OO software structure). For the autonomous distributed system control, several inter-subsystem communication methods are proposed and evaluated. This autonomous control method will lead to a highly reliable communications system with large capacity. For the OO software structure, experimental results from the implementation of a prototype system are given. Its distributed environment should lead to high reliability by extending the CHILL run-time routine (RTR). This software structure promises to provide service quickly, to reduce costs, and make the development of each layer's software independent.
