Abstract

As the complexity of software increases, there is a need to describe and evaluate the system structure or software architecture. The software architecture of a distributed system is particularly important when a system is allowed to evolve or be reconfigured during its execution, without major interruption. In this paper, we study the formalisation of evolving distributed software architectures and present a formal framework, based on Z, for the development of this type of software architecture. The paper also includes an example which shows how our framework can be applied to specify properties of evolving distributed software architectures.
