Abstract:
As a general framework, UNITY does not offer any specific facility for
the design of distributed systems. For such systems, distribution
aspects must be represented at a low level, resulting into intricated
models and proofs. To provide a more abstract view of distributed
systems, we propose two extensions to UNITY. The first one is an
observation relation which is integrated in UNITY semantics
to provide an abstract communication mechanism. The second one is a
mapping operator which accounts for the true parallelism of
distributed systems. The paper illustrates, through different
examples, how these extensions can be used to help the design of
distributed systems in UNITY.
