Abstract
Description
Procédé de liaison d'une machine de traitement de données à un réseau de transmission et automate de sélection du réseau.Method for connecting a data processing machine to a transmission network and network selection automaton.
Les télécopieurs sont des machines de bureau, de traitement de données, permettant de transmettre à un correspondant ou de recevoir de lui les données d'un support imprimé à travers un ou plusieurs réseaux de transmission, aujourd'hui en relativement grand nombre. Citons, par exemple, - le réseau téléphonique commuté RTC, - le réseau à intégration de services RNIS, - le réseau Internet, - les réseaux locaux LAN (Eternet, Internet), - les réseaux cellulaires de radiotéléphonie (GSM, ...).Fax machines are office machines, data processing, allowing to transmit to a correspondent or to receive from him the data of a printed medium through one or more transmission networks, today in relatively large number. We can cite, for example, - the PSTN switched telephone network, - the ISDN integrated services network, - the Internet network, - local area networks LAN (Internet, Internet), - cellular radiotelephony networks (GSM, ...) .
Les télécopieurs modernes peuvent être reliés directement ou indirectement à n'importe lequel de ces réseaux. Du fait de leur multiplicité, la demanderesse s'est posé le problème de leur exploitation, c'est-à-dire de leur choix pour transmettre à travers eux les données d'un support imprimé, dans le cas des télécopieurs, mais, de façon générale, toutes données d'une machine de bureau, de traitement de données, tels les ordinateurs personnels, agencée pour être reliée à l'un ou l'autre de ces réseaux.Modern fax machines can be connected directly or indirectly to any of these networks. Because of their multiplicity, the plaintiff posed the problem of their exploitation, that is to say of their choice to transmit through them the data of a printed medium, in the case of fax machines, but, of generally, all data from an office machine, data processing, such as personal computers, arranged to be connected to one or the other of these networks.
A cet effet, la présente demande concerne tout d'abord un procédé de liaison, à l'un des réseaux d'une pluralité de réseaux de transmission, d'une machine de traitement de données pour transmission de ses données à des correspondants, caractérisé par le fait que - pour chacun des réseaux, on établit une liste de paramètres, - au moment d'établir la liaison, on détermine les valeurs des paramètres, - on applique, à au moins une ligne de paramètres des réseaux, un algorithme de sélection et - on sélectionne l'un des réseaux auquel on relie la machine.To this end, the present application firstly relates to a method of linking, to one of the networks of a plurality of transmission networks, a data processing machine for transmission of its data to correspondents, characterized by the fact that - for each of the networks, a list of parameters is established, - when establishing the connection, the values of the parameters are determined, - an algorithm is applied to at least one row of network parameters selection and - one of the networks to which the machine is connected is selected.
Dans la mise en oeuvre préférée du procédé de l'invention, on établit des lignes de paramètres d'exploitation extrinsèques des réseaux, des lignes de paramètres d'exploitation intrinsèques des réseaux et des lignes de paramètres de correspondants attributifs de réseaux.In the preferred implementation of the method of the invention, lines of extrinsic operating parameters of the networks are established, lines of intrinsic operating parameters of the networks and lines of parameters of corresponding network attributes.
Dans ce cas, et n'appliquant l'algorithme de sélection qu'aux paramètres d'exploitation extrinsèques des réseaux, avant d'appliquer l'algorithme de sélection, on tente de reconnaître un paramètre attributif ou un paramètre d'exploitation intrinsèque et, en cas de reconnaissance, on inhibe l'application de l'algorithme et on sélectionne le réseau du paramètre reconnu auquel on relie la machine.In this case, and applying the selection algorithm only to the extrinsic operating parameters of the networks, before applying the selection algorithm, an attempt is made to recognize an attribute parameter or an intrinsic operating parameter and, in the event of recognition, the application of the algorithm is inhibited and the network of the recognized parameter to which the machine is connected is selected.
Avantageusement, l'algorithme de sélection est un algorithme de comparaison des valeurs de paramètre.Advantageously, the selection algorithm is an algorithm for comparing the parameter values.
L'invention concerne également un automate de sélection d'un réseau de transmission pour y relier une machine de traitement de données, pour la mise en oeuvre du procédé de liaison de l'invention, comprenant, autour d'un contrôleur commandant un port de sortie, un tableau de commande, avec un clavier de touches de saisie, une mémoire de stockage de paramètres de réseaux et d'adresses de correspondants et contenant une zone d'apprentissage.The invention also relates to an automaton for selecting a transmission network for connecting a data processing machine to it, for implementing the linking method of the invention, comprising, around a controller controlling a communication port. output, a control panel, with a keyboard for input keys, a memory for storing network parameters and addresses of correspondents and containing a learning zone.
L'invention sera mieux comprise à l'aide de la description suivante d'une mise en oeuvre du procédé et d'une réalisation particulière de l'automate de sélection de l'invention, en référence à la figure unique annexe représentant schématiquement l'automate.The invention will be better understood with the aid of the following description of an implementation of the method and of a particular embodiment of the selection automaton of the invention, with reference to the single annex figure schematically representing the automaton.
Dans la mémoire 2 d'un automate 1, on constitue une matrice 3 de colonnes de réseaux de transmission et de lignes de paramètres divisées en trois groupes de lignes
Premier groupe, lignes de paramètres d'exploitation extrinsèques
Ces paramètres concernent essentiellement la qualité de service,
c'est-à-dire, et notamment, la vitesse, le coût, la fiabilité, la
confidentialité de la transmission, la qualité de restitution; ces
paramètres varient considérablement dans le temps et d'un réseau à
un autre.In the memory 2 of a PLC 1, a matrix 3 of columns of transmission networks and of parameter lines divided into three groups of lines is formed.
First group, lines of extrinsic operating parameters
These parameters mainly concern the quality of service,
that is to say, and in particular, the speed, the cost, the reliability, the
confidentiality of transmission, quality of restitution; these
settings vary greatly over time and from network to network
another.
Deuxième groupe, lignes de paramètres d'exploitation intrinsèques
Comme exemples de paramètres de ce groupe, on peut considérer
la discrétion des émissions sur les réseaux cellulaires et, à
l'inverse, l'éclatement quasi-omnidirectionnel des transmissions
sur le réseau Internet.Second group, intrinsic operating parameter lines
As examples of parameters of this group, we can consider
the discretion of transmissions on cellular networks and, at
conversely, the almost omnidirectional bursting of transmissions
on the Internet.
Troisième groupe, lignes de paramètres attributifs de réseaux.Third group, lines of network attribute parameters.
Comme exemples de paramètres de ce type, on peut considérer
une adresse de correspondant incluant un caractère particulier tel
que @, impliquant une transmission par le réseau Internet, . une
transmission "Groupe 4", impliquant le réseau RNIS, ou e une
transmission "MAIL", impliquant une transmission vers une boite à
lettres du réseau Internet.As examples of parameters of this type, we can consider
a correspondent address including a special character such
that @, involving transmission via the Internet,. a
"Group 4" transmission, involving the ISDN network, or a
"MAIL" transmission, implying a transmission to a
Internet letters.
Outre la matrice des paramètres des réseaux, on crée également dans la mémoire de l'automate un annuaire de correspondants 4, avec leurs adresses, éventuellement mis à jour à chaque communication ainsi qu'une zone 5 d'apprentissage des réseaux complétée également à chaque communication et pouvant permettre une saisie plus rapide des paramètres extrinsèques et intrinsèques des réseaux aux moments de l'établissement des liaisons.In addition to the network parameters matrix, a directory of correspondents 4 is also created in the memory of the controller, with their addresses, possibly updated with each communication, as well as a zone 5 for learning networks also completed at each communication and can allow faster entry of extrinsic and intrinsic network parameters at the time of connection establishment.
L'automate 1 est également pourvu d'un tableau 6 de commande et de saisie des paramètres à retenir et à privilégier permettant soit une sélection manuelle de réseau, soit une sélection automatique sur un port de sortie 8, après détermination des valeurs des paramètres et application d'un algorithme de sélection.The automaton 1 is also provided with a control and input table 6 for the parameters to be retained and preferred allowing either a manual network selection, or an automatic selection on an output port 8, after determination of the values of the parameters and application of a selection algorithm.
Ainsi, et pour la sélection manuelle de réseau, l'opérateur peut actionner l'une des touches d'un clavier de touches 7 du tableau 6 correspondant respectivement aux divers réseaux. Thus, and for manual network selection, the operator can actuate one of the keys of a keyboard of keys 7 of table 6 corresponding respectively to the various networks.
Le tableau 6 permet la saisie de paramètres intrinsèques de réseau commandant la sélection du réseau sur le port de sortie 8.Table 6 allows the entry of intrinsic network parameters controlling the network selection on the output port 8.
En cas de sélection automatique, après détermination et saisie des valeurs des paramètres sur le tableau 6, le contrôleur 9 de gestion de l'automate, et en liaison avec tous ses autres organes, après éventuelle reconnaissance des paramètres intrinsèques et des paramètres attributifs, met en oeuvre l'algorithme de sélection stocké dans la mémoire 2 pour sélection subséquente du réseau sur le port 8.In the case of automatic selection, after determining and entering the values of the parameters in table 6, the controller 9 for managing the automaton, and in conjunction with all its other organs, after possible recognition of the intrinsic parameters and of the attributive parameters, implementing the selection algorithm stored in memory 2 for subsequent selection of the network on port 8.
L'automate comporte aussi, à titre d'éléments d'interface hommemachine, un écran 10 et une imprimante 11 reliés au contrôleur 9. The PLC also includes, as human machine interface elements, a screen 10 and a printer 11 connected to the controller 9.
