CONNECTION MODE CONTROL DEVICE, CONNECTION MODE CONTROL METHOD, AND CONNECTION MODE CONTROL PROGRAM

摘要

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 N contained in a network system NS including a server Sand a plurality of nodes N constituting a plurality of hierarchies and connected to one another, wherein a content is distributed from the server S to the respective nodes N, it is checked whether a content relay function in a node located at the uplink with respect to the node N 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 N in the process executed in the node N is smaller than the consumption speed before the relay function has stopped.
