Abstract: Provided is a network monitor for a mobility network used in a mobility entity. The mobility network is formed of a source unit, a destination unit, and one or more repeaters. Each repeater includes a network monitor that receives, from the source unit, an announcement for a bandwidth reservation. The announcement includes a value of a first bandwidth requirement for the source unit to perform first data communication. The network monitor further determines a determination result of whether to reserve the first bandwidth by comparing the value of the first bandwidth with a range of values of a second bandwidth for the first data communication specified in a white list stored in a database. The network monitor reserves the first bandwidth for performing the first data communication depending on the determination result, and transmits, to the source unit, a reservation status of the first bandwidth.

Abstract: An in-vehicle relay device prevents an anomaly of a control command exchanged over networks having different transmittable data sizes in a frame. The in-vehicle relay device relays communication between multiple control devices in a vehicle over the networks to which the control devices are connected. The in-vehicle relay device receives control data from a first control network. The control data includes, in a frame, a plurality of control commands to be executed by at least one of the control devices. The in-vehicle relay device determines, as a first determination, whether types of the control commands included in the frame form a first combination that is preset as a combination of control commands that are executable simultaneously. The in-vehicle relay device thereafter determines, as a second determination, whether the control data is anomalous by using the result of the first determination, and outputs the result of the second determination.

Abstract: An abnormality detection apparatus for a mobility entity and for detecting an abnormality in a network system is provided. The network system includes a first network and a second network that use different communication protocols. A first communication circuit receives state information indicating a state of the mobility entity. The state information is acquired from the second network. A second communication circuit transmits and receives a first frame according to a communication protocol used in the first network. A memory stores an abnormality detection rule. A processor detects, based on the state information and the abnormality detection rule, whether a control command included in the first frame received by the second communication circuit is abnormal. In a case where the control command is abnormal, the processor prohibits the control command from being transmitted.
