The paper "Specifying Distributed Software Architectures" by Jeff Magee, Naranker Dulay, Susan Eisenbach, and Jeff Kramer addresses the need for clear and sound design specifications at the architectural level of distributed systems. The authors introduce the Darwin notation, a declarative binding language designed to specify the high-level organization of interconnected components. Darwin supports both static and dynamic structures, with services facilitating component interactions. The language is operational, meaning it can be used to direct the construction of the desired system at runtime. The operational semantics of Darwin are described using the π-calculus, a calculus of mobile processes, which provides a model for the correctness of the Darwin elaboration process. The paper aims to provide a robust notation for specifying and constructing distributed software architectures, emphasizing the management of system structure and the ability to handle diverse interaction mechanisms.The paper "Specifying Distributed Software Architectures" by Jeff Magee, Naranker Dulay, Susan Eisenbach, and Jeff Kramer addresses the need for clear and sound design specifications at the architectural level of distributed systems.
