Message sequence charts (MSCs) are an appealing visual formalism often used to capture system requirements in the early stages of design. An important question concerning MSCs is the following: how does one convert requirements represented by MSCs into state-based specifications? A first step in this direction was the definition in [9] of regular collections of MSCs, together with a characterization of this class in terms of finite-state distributed devices called message-passing automata. These automata are, in general, nondeterministic. In this paper, we strengthen this connection and describe how to directly associate a deterministic message-passing automaton with each regular collection of MSCs. Since real life distributed protocols are deterministic, our result is a more comprehensive solution to the synthesis problem for MSCs. Our result can be viewed as an extension of Zielonka’s theorem for Mazurkiewicz trace languages [6,19] to the setting of finite-state message-passing systems.
