Abstract

Coordination languages emerged for programming interaction protocols among components in component-based systems, in terms of connectors. One such language is Reo. Reo facilitates compositional construction of complex composite connectors out of simple primitive ones. Unlike the behavior of connectors in other coordination languages, the behavior of a connector in Reo may depend on whether its coordinated components are ready for Open image in new window . Such behavior is called “context-sensitivity”, and its formalization—a nontrivial problem—has received considerable attention from the community. In this paper, I study three common and historically significant primitives in Reo—context-sensitive LossySync, FIFOn, and LossyFIFOn—and prove that they have inconsistent informal semantics. Moreover, four major formal semantics of Reo do not correspond with its foremost alternative informal semantics.
