Abstract

Système de simulation de l'environnement d'un calculateur de système de commutation, comprenant un calculateur de simulation CPd du réseau de communication SN et des périphériques associés que le calculateur de système CPa doit commander et une interface SI interconnectant les deux calculateurs. Le calculateur de simulation est programmé pour simuler une charge de trafic dans le réseau de commutation complet selon la distribution de Bernouilli. Il peut mesurer la durée d'exécution de différents programmes par le calculateur de système, par exemple un programme de recherche d'itinéraire, dont la répétition permet de calculer le temps moyen d'exécution dans des conditions de trafic données. L'invention s'applique plus généralement à la simulation d'environnement de systèmes à temps réel.System for simulating the environment of a switching system computer, comprising a simulation computer CPd of the communication network SN and associated peripherals that the system computer CPa must control and an interface SI interconnecting the two computers. The simulation calculator is programmed to simulate a traffic load in the entire switching network according to the Bernouilli distribution. It can measure the duration of execution of different programs by the system computer, for example a route finder program, the repetition of which calculates the average execution time under given traffic conditions. The invention applies more generally to the simulation of the environment of systems in real time.
