A vehicular network is a closed network with known sources, destinations, and network connections that can be mapped in advance, and used to identify network resources needed to transmit a packet from a source to a destination. A network module can determine the source destination, and a priority of a packet based on the packet's content. Using the source and destination information, along with a network topology data, the network module can determine if two packets need the same network resources to be delivered to their destination. When the two packets do not use the same resources, there is no conflict, and the packets can be transmitted concurrently regardless of whether one of the packets has a higher priority than another packet. If there is a conflict, the network module transmits the packets based on the packets' priorities.

A power-supply control apparatus uses a margin setting unit to set the value of a margin that is added to a request voltage value VID 1 of an electronic device, which dynamically changes the operation voltage. A margin adding unit calculates a control voltage value VID 2 by adding the margin to the request voltage value VID 1 and outputs the control voltage value VID 2 to a power-supply apparatus. Therefore, the power-supply apparatus can supply a margin-included voltage value that is changed in accordance with a change in the operation voltage of the electronic device. Accordingly, it is possible to check the electronic device, which dynamically changes its operation voltage, by using a margin that is properly set.
