Specification and Description Language (SDL) is a formal object-oriented language for modelling real-time interactive systems. It is an International Telecommunication Union (ITU) standard. A software architecture is the structure of a program including a set of inter-communication components. These components are often independently executable super objects. We use the architecture design to answer questions such as how the super objects fit together and how to reuse them. We investigate the feasibility and benefits of using SDL to represent the dynamic aspect of the software architectures. It includes a methodology and an accompanying tool, Workflow-to-SDL-Transformation (W2S), for deriving software architectures in SDL from an originally informal use case flow definition. The focus of the research is in the telecom domain, many of which are real-time interactive systems. We applied our method to a partial telecom system. The experimental results are collected and presented. Our result shows the feasibility and benefits of representing the dynamic software architecture in SDL
