Abstract:
Several commercial software allow to model and simulate an architecture at the physical network layer. However, none of them allow to simulate the operating scheme of a distributed object architecture. The aim of this article is to propose a methodology
based on the DEVS formalism for the modeling and the simulation of distributed object architectures described at the formal specification layer. This methodology can be used in order to validate the approach before the real implementation. Our basic approach is to extend the classical {}``Waterfall'' software model with three different software description layers: the informal specification layer, the formal specification layer and the code layer. The first layer describes a software using a textual, human-readable approach. The second one describes a software using an approach combining, for instance an UML description and little pieces of code for some precise details of the implementation. Finally, the third layer describes a software only using code. We will see that this methodology occurs at what we call the second layer, e.g. the formal description layer.
