Abstract

SYSTEME DE STOCKAGE DE DONNEES DANS LEQUEL DES MESSAGES ISSUS DE PLUSIEURS SOURCES SONT INTRODUITS EN MEMOIRE DYNAMIQUE DANS DES FILES D'ATTENTE CONSTITUEES A RAISON D'UNE FILE PAR USAGER (TERMINAL AUQUEL LE MESSAGE EST DESTINE) ET PAR NIVEAU DE PRIORITE. UNE MEMOIRE AUXILIAIRE 2 COMPORTE UNE CELLULE DE COMMANDE ASSOCIEE A CHAQUE CELLULE DE LA MEMOIRE DE MESSAGES 7 ET CONTENANT UN MOT DE COMMANDE DONT UNE PARTIE INDIQUE L'ETAT LIBRE OU OCCUPE DE LA CELLULE DE MEMOIRE CORRESPONDANTE. APRES TRANSFERT D'UN MESSAGE D'UNE MEMOIRE TAMPON D'ENTREE 4 A LA MEMOIRE DE MESSAGES SOUS LE CONTROLE DE L'INDICATION PRECEDENTE, LE MOT DE COMMANDE FOURNIT DIFFERENTES INFORMATIONS NECESSAIRES A SON TRAITEMENT, NOTAMMENT L'IDENTITE DE L'USAGER DESTINATAIRE ET LE NIVEAU DE PRIORITE DU MESSAGE. APPLICATION PARTICULIERE AU SOUS-SYSTEME DE TRANSMISSION DE MESSAGES ENTRE LES CENTRAUX D'UN SYSTEME NUMERIQUE DE TELECOMMUNICATIONS.DATA STORAGE SYSTEM IN WHICH MESSAGES COMING FROM SEVERAL SOURCES ARE INTRODUCED IN DYNAMIC MEMORY IN QUEUES ESTABLISHED BY ONE QUEUE PER USER (TERMINAL TO WHICH THE MESSAGE IS DESTINED) AND BY PRIORITY LEVEL. AN AUXILIARY MEMORY 2 INCLUDES A CONTROL CELL ASSOCIATED WITH EACH CELL OF THE MESSAGE MEMORY 7 AND CONTAINING A CONTROL WORD OF WHICH PART INDICATES THE FREE OR OCCUPIED STATE OF THE CORRESPONDING MEMORY CELL. AFTER TRANSFER OF A MESSAGE FROM AN INPUT BUFFER 4 MEMORY TO THE MESSAGE MEMORY UNDER THE CONTROL OF THE PREVIOUS INDICATION, THE CONTROL WORD PROVIDES VARIOUS INFORMATION NECESSARY FOR ITS PROCESSING, IN PARTICULAR THE IDENTITY OF THE RECIPIENT USER AND THE PRIORITY LEVEL OF THE MESSAGE. SPECIAL APPLICATION TO THE SUB-SYSTEM FOR TRANSMISSION OF MESSAGES BETWEEN THE CENTRALS OF A DIGITAL TELECOMMUNICATIONS SYSTEM.
