    Abstract: An anomaly detection device for detecting anomaly in frames flowing through an in-vehicle network system includes: an obtainer that obtains one or more frames; a first holder holding a first rule defining a rule indicating that when a frame satisfies a first condition based on a source or a destination, the frame is to be transferred; a first frame controller that transfers the one or more frames in accordance with the first rule; a second holder holding a second rule defining a rule indicating that a frame satisfying a second condition is to be determined as being anomalous; and a second frame controller that performs, in accordance with the second rule, an anomaly detection process on each of the one or more frames transferred by the first frame controller. When an anomalous frame is detected, the second frame controller provides or stores a detection result.

    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 electronic control unit connected to a bus of a first network where first-type frames are transmitted following a first communication protocol and a second network where second-type frames are transmitted following a second communication protocol in an onboard network system. The electronic control unit sequentially receives the first-type and the second-type frames from the bus and the second network respectively, and stores in first and second reception buffers, respectively. The electronic control unit sequentially generates first-type data and second-type data by referencing the contents of the first reception buffer and the second reception buffer, and stores the first-type and second-type data in first and second transmission buffers, respectively. The first-type data is traveling control data for a vehicle, and the second-type data is other data. The first-type or second-type data that is priority type data is transmitted with priority.

    Abstract: A hub is connected to first and second networks where first-type and second-type frames are transmitted following first and second communication protocols. The hub sequentially receives each of the first-type and second-type frames, and stores data in first and second reception buffers. If the destination of data stored in the first and second reception buffers is the first network, the hub stores the data in a first transmission buffer. If the destination is the second network, the hub stores the data in a second transmission buffer. If the first transmission buffer is a priority transmission buffer, the hub transmits first yet-to-be-transmitted data in the first transmission buffer with priority. If the second transmission buffer is the priority transmission buffer, the hub transmits second yet-to-be-transmitted data in the second transmission buffer with priority.
