Title (EN) ENHANCED COMMUNICATIONS NETWORK TESTING AND CONTROL SYSTEM
(FR) SYSTEME AMELIORE DE COMMANDE ET D"ESSAI D"UN RESEAU DE COMMUNICATION
Abstract: front page image
(EN)A network control and test system (10, 20) for application to data communications networks. In a first mode of operation, the system learns the network configuration automatically and builds a table describing the network configuration. In a second mode of operation, the system automatically monitors the status of the network and each of its component units, periodically polling the network for changes of status and updating the information in the network configuration table to reflect such changes. In a third mode of operation, selective sites in the network may be tested under control of the system at previously selected and entered times of day, at which times previously chosen tests are performed without the need for operator intervention. In a fourth mode, an operator can manually command the system to perform certain tests and control functions. A central site in the network includes the primary components of the system and each remote site includes a remote test module (34) which operates under the control of and in cooperation with the central site equipment. The central site equipment includes a three-tiered, partially distributed data processing system (12, 22, 24) having a semi-autonomous data processing system at each tier. Each of the tiers has predetermined functions and responsibilities. Extremely flexible and powerful operation is provided by this architecture.
(FR)Un systeme d"essai et de commande d"un reseau (10, 20) s"applique a des reseaux de communication de donnees. Dans un premier mode de fonctionnement, le systeme apprend la configuration du reseau automatiquement et construit un tableau decrivant la configuration du reseau. Dans un second mode de fonctionnement, le systeme controle automatiquement l"etat du reseau et chacun de ses composants, interrogeant periodiquement le reseau sur ses changements d"etat et mettant a jour l"information dans le tableau de configuration du reseau pour y refleter ces changements. Dans un troisieme mode de fonctionnement, des endroits ou points choisis du reseau peuvent etre testes sur commande du systeme a des moments du jour predetermines, durant lesquels des tests etablis anterieurement sont effectues sans qu"un operateur n"ait besoin d"intervenir. Dans un quatrieme mode, un operateur peut commander manuellement le systeme pour effectuer certaines fonctions d"essai et de controle. Un site ou emplacement central du reseau comprend les composants primaires du systeme et chaque site eloigne comprend un module d"essai a distance (34) qui fonctionne sous la commande et en cooperation avec l"equipement du site central. L"equipement du site central comprend un systeme de traitement de donnees a distribution partielle, a trois rangees (12, 22, 24) ayant un systeme de traitement de donnes semi-autonome a chaque rangee ou etage. Chacun des etages possede des fonctions et des responsabilites predeterminees. Cette conception permet d"obtenir un fonctionnement extremement souple et puissant.
