✦ Synopsis

Public switching systems are severely real-time and multiprocessing, very large, long-lived, and frequently modified. Programs that control switching systems therefore are required not only to have run-time efficiency but also to be easy to maintain and expand. This paper proposes a concurrent object model and an object-oriented switching program structure. The concurrent object model ensures simple and efficient real-time multiprocessing. Also, it allows logical switching components to be implemented as 'objects" in software, and the structure of the program coincides with the structure of the logical model. The program structure proposed here uses distributed call processing, which allows building-block structured switching systems. A prototype switching program confirmed the effectiveness of this approach and showed that the static and dynamic overheads are within the capacity of present VLSI technology.
