Abstract

This paper describes the use of Ada95/DSA as middleware for modeling network's entities into distributed objects which can be used for both distributed execution and simulation without transformation of the model. First, general issues of simulation of network's entities are briefly presented. Then, the paper shows how DSA features are used to abstract these entities in a manner as they can be executed or simulated on a cluster of workstations. The DSA based model of distributed simulation is built on a combination of two kinds of classes: the first one support general purpose of distributed objects computing and the second deal with the development of distributed network elements. To illustrate the feasibility of this approach, a partial implementation of classes that have been used to model routers running a subset of border gateway protocol (BGP) is presented.
