Abstract: A relay device is provided. The relay device includes: an acquisition unit acquiring data necessary for an upgrade processing from an upgrading tool, which performs the upgrading processing to an ECU connected to a vehicle-mounted network; a relay unit providing the data, via the vehicle-mounted network, to a target ECU which is subject to the upgrade processing; a suspend instructing unit transmitting, via the vehicle-mounted network, a suspend command which instructs the non-target ECU to shift to a suspend state in which a transmission of other data to the non-target ECU via the vehicle-mounted network is suspended in response to a start of the upgrade processing; and a cancel instructing unit instructing, via the vehicle-mounted network, the non-target ECU to cancel the suspend state when the upgrade processing is completed.
