CA 2614159

According to the invention, connection information (vcxIndex) representing each connection (AE1...n) of the at least one communication device (KE1...n) to a multiplexer device (MUX) is stored in the multiplexer device, the connection information (vcxIndex) is allocated to the at least one communication network specific address (IP) of the at least one communication device (KE1...n) connected to the connector (AE1...n). A message (ARP-REQUEST) sent to the multiplexer device (MUX) is detected and at least one target address (ZA) contained therein is compared with the stored communication network specific addresses (IP). On determination of an at least partial match of the compared pieces of information (IP, ZA) the message (ARP-REQUEST) or information or initiating the communication relationship device is forwarded to the at least one connector (AE1...n) represented by the allocated connector information (vcxIndex). Advantageously, the range of the information broadcast over the communication network or the message receipt is reduced and the data security increased so that the broadcast information or messages can not be received by all users.

Selon l'invention, des informations de raccordement (vcxIndex) représentant le raccordement (AE1...n) du ou des dispositifs de communication (KE1...n) à un dispositif multiplexeur (MUX) sont stockées dans le dispositif multiplexeur, la ou les adresses (IP) spécifiques du réseau de communication et relatives aux dispositifs de communication (KE1...n) raccordés aux raccordements (AE1...n) étant associées à ces informations de raccordement (vcxIndex). Un message (ARP-REQUEST) transmis au dispositif multiplexeur (MUX) est détecté et au moins une adresse cible (ZA) contenue dans ce message est comparée avec les adresses (IP) spécifiques du réseau de communication stockées. Si les informations comparées (IP, ZA) coïncident au moins partiellement, le message (ARP-REQUEST) ou une information lançant l'établissement de la liaison de communication sont transmis aux raccordements (AE1...n) représentés par les informations de raccordement (vcxIndex) associées. De préférence, la taille des informations transmises par l'intermédiaire du réseau de communication ou le volume des messages sont réduits et la sécurité des données est accrue, les informations ou les messages diffusés ne pouvant plus être reçus par tous les abonnés.
