Abstract

DANS UN SYSTEME DE RESEAU A BUS EN BOUCLE OU PLUSIEURS UNITES DE TRAITEMENT SONT CONNECTEES A UN BUS EN BOUCLE UNIDIRECTIONNELLE ET OU CHAQUE UNITE DE TRAITEMENT PRODUIT UN MESSAGE DE TRANSMISSION AVEC UN NUMERO DE NIVEAU QUI DESIGNE LA PRIORITE DU MESSAGE D'UTILISER LE BUS, CHAQUE UNITE DE TRAITEMENT DES NOEUDS, DANS LAQUELLE EST PRODUITE LA DEMANDE DE TRANSMISSION DU MESSAGE, TRANSMET AU BUS EN BOUCLE UNE DONNEE DE COMMANDE DU BUS COMPRENANT UN NUMERO DE NIVEAU DU MESSAGE QUI Y EST PRODUIT ET UNE DONNEE QUI REPRESENTE LA PRIORITE D'UTILISER LE BUS ATTRIBUEE A CHAQUE UNITE DE TRAITEMENT DE NOEUD POUR CE NUMERO DE NIVEAU. CHAQUE UNITE DE TRAITEMENT DE NOEUD COMPARE LA DONNEE DE COMMANDE DU BUS TRANSMISE DE CELLE-CI A UN NOEUD SUIVANT AVEC UNE DONNEE DE COMMANDE RECUE D'UN NOEUD PRECEDENT ET ENSUITE TRANSMET SEULEMENT LA DONNEE PLUS GRANDE ENTRE LES DEUX COMPAREES, DE FACON A S'ASSURER QUE SEULE UNE DONNEE DE COMMANDE DU BUS SE PROPAGE AUTOUR DE LA BOUCLE ET QUE LA PRIORITE D'UTILISER LE BUS EN BOUCLE EST ATTRIBUEE A UNE DES UNITES DE TRAITEMENT DE NOEUDS QUI A PRODUIT LA DONNEE DE COMMANDE MENTIONNEE CI-DESSUS.
