Abstract
In a control system for controlling a network providing a service by using a virtual network function, the control system includes: a QoS estimation unit configured to estimate QoS at a current time of each flow in the network on a basis of observation information of the network; a QoS degradation detection unit configured to determine whether or not there QoS degradation flow is present on a basis of an estimation result by the QoS estimation unit; and a control determination unit configured to determine a control content and an execution timing thereof by solving an optimization problem with minimizing a total of degradation amounts in a time range from the current time to future for all flows as an objective function when the QoS degradation flow is determined to be present by the QoS degradation detection unit.
