  • Publication number: 20230245559
    Abstract: A server receives video data from a moving body. A traveling speed control apparatus controls a traveling speed of the moving body. A quality monitoring unit monitors video quality of the video data received by the server. A speed upper limit calculation unit calculates, by using the video quality and a monitoring required condition of the video data, a maximum value of a traveling speed satisfying the monitoring required condition as an upper limit value of a traveling speed of the moving body. A speed control unit controls a traveling speed of the moving body to be equal to or lower than the calculated upper limit value.

  • Patent number: 11653255
    Abstract: A control apparatus (40) determines a control value to be supplied to a node (604) in a communication network so as to achieve a setpoint of Quality of Service (QoS) performance required by a traffic flow transferred through the communication network. This control value causes the node (604) to adjust allocation of network resources to the traffic flow. The control apparatus (40) corrects the control value to be supplied to the node (604) on the basis of a control delay between the control apparatus (40) and the node (604) and on the basis of a trend in changes in a traffic-related parameter. It is thus, for example, possible to contribute to stabilizing control for guaranteeing QoS performance required by a traffic flow even when there is a non-negligible control delay.
