There is provided a network control device capable of surely distributing a content even when a relay function of one of the nodes contained in a network stops, without affecting the process in nodes below the node and while improving the re-liability of the network system itself. When controlling a node contained in a network system including a server and a plurality of nodes constituting a plurality of hierarchies and connected to one another, wherein a content is distributed from the server to the respective nodes, it is checked whether a content relay function in a node located at the uplink with respect to the node in the content distribution has stopped. When the stop of the relay function is detected, control is performed so that the consumption speed of the content accumulated in the lower node in the process executed in the node is smaller than the consumption speed before the relay function has stopped.
