Use Cases for Distributed Real-time Software Architectures

Abstract

This paper describes how use cases can be applied to the architectural design of distributed real-time applications. In order to benefit from use cases in distributed real-time design, it is necessary to extend use cases, particularly in the design phase, when important design decisions need to be made. To achieve this, use cases are integrated with CODARTS(Concurrent Design Approach for Real-Time Systems) distributed design concepts. Three different types of architectural use cases are described, client/server use cases, subscription use cases and real-time control use cases. Different forms of message communication are associated with the different use case types. the software architecture of the distributed real-time system is achieved by composing it from the use cases.
