That is, multiple pieces of setting information are stored in the memory 21 of the SDN controller 15 in a state in which updates by the OTA master 30 are permitted. Therefore, each piece of setting information stored in the memory 21 can be updated appropriately in response to changes in the functions of the in-vehicle device 14 due to software updates, etc.

The transmission of the information such as the type may be used as the notification of the completion of the software update. In this case, in S25, only the information such as the type is transmitted from the OTA master 30 to the SDN controller 15.

  • the in-vehicle network 10 may be configured so that communication between the in-vehicle devices 14 occurs at a layer other than the data link layer. That is, the SDN controller 15 in the above embodiment may be configured as a device that controls the communication settings of each relay device in an in-vehicle network provided with multiple relay devices that forward messages.
  • the SDN controller 15 may be configured as any configuration having the function of a setting device that updates the communication settings of multiple communication devices installed in the in-vehicle network 10.

Abstract

Un contrôleur SDN (15) pour contrôler de paramètres de communication d'une pluralité de commutateurs SDN (12) qui sont installés dans un réseau embarqué (10) et effectuer un transfert de trame, comprend une mémoire (21) dans laquelle une pluralité d'éléments d'informations de paramétrage sont stockés. Le contrôleur SDN (15) effectue un traitement de sélection et un traitement de mise à jour lorsqu'un appareil embarqué (14), employé pour effectuer une communication de trame, est connecté au réseau embarqué. Le traitement de sélection est un traitement consistant à sélectionner l'un de la pluralité d'éléments d'informations de paramétrage sur la base des informations de type de l'appareil embarqué nouvellement connecté (14). Le traitement de mise à jour est un traitement consistant à mettre à jour le paramètre de communication de chaque commutateur SDN (12) sur la base des informations de paramétrage sélectionnées par le traitement de sélection.
