Abstract
A control apparatus () determines a control value to be supplied to a node () 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 () to adjust allocation of network resources to the traffic flow. The control apparatus () corrects the control value to be supplied to the node () on the basis of a control delay between the control apparatus () and the node () 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.
