Abstract

Prevent DCS control nodes from becoming overloaded. [Solution] A control node 10 of an embodiment has an execution unit 131, a selection unit 133, a determination unit 136, and a request unit 137. The execution unit 131 executes an assigned task. The selection unit 133 selects one of the assigned tasks when the magnitude of the load on the control node exceeds a threshold. The determination unit 136 determines whether the task selected by the selection unit 133 is a real-time process. If the determination unit 136 determines that the task is a real-time process, the request unit 137 requests a control node other than the control node to execute the task among multiple control nodes, and if the determination unit 136 does not determine that the task is a real-time process, the request unit 137 requests a server to execute the task.
