Title: DEVICE AND METHOD FOR COMMUNICATION NETWORK
Abstract:
A control device (40) determines a control value to be provided to a node (604) in a communication network so as to achieve a target value (setpoint) for the QoS performance required by a traffic flow transferred over the communication network. The control value causes the node (604) to adjust the allocation of network resources to the traffic flow. Furthermore, the control device (40) corrects the control value to be provided to the node (604) on the basis of a change trend of a parameter related to traffic and the control delay between the control device (40) and the node (604). Due to this configuration, the present invention can contribute, for example, to stabilizing control for guaranteeing the QoS performance required by a traffic flow, even in the presence of a control delay of a magnitude that cannot be ignored.
