Abstract

We present GCCS, a graphical coordination language for hierarchical concurrent systems. GCCS, which is implemented in the Concurrency Factory design environment, represents a coordination model based on process algebra. Its coordination laws, given as a structural operational semantics, allow one to infer atomic system transitions on the basis of transitions taken by system components. We illustrate the language's utility by exhibiting a GCCS-coordinated specification of the Rether real-time ethernet protocol. The specification contains both graphical and textual components.
