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.

Abstract: In order to provide a control apparatus achieving an efficient control of network using a machine learning, a control apparatus includes a learning unit and a control unit. The learning unit learns an action for controlling the network. The control unit controls the network by setting a control parameter to an apparatus included in the network based on an action obtained from a learning model generated by the learning unit. The control unit decides the control parameter based on an influence of the action obtained from the learning model on a state of the network.

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.
